Steps for selecting a pressure switch
The deciding factors in the selection of a pressure switch for use on control circuits1 depend on the
requirements of the application. Consider the following requirements to help determine the
appropriate catalog number for your application.
1. Setpoints: Do you want to control/monitor one setpoint or two?
• One setpoint: xed differential • Two setpoints: adjustable differential
2. Fluids: What uids do you want to control?
• Hydraulic oil, air, fresh water ≤ 70 °C (158 °F) • Steam
• Hydraulic oil, air, fresh water ≤ 160 °C (320 °F) • Corrosive uid ≤ 160 °C (320 °F)
• Sea water ≤ 70 °C (158 °F) • Viscous uid ≤ 160 °C (320 °F)
• Sea water ≤ 160 °C (320 °F)
Ensure that the wetted parts of the switch are compatible with the system uid.
3. Pressure range: What pressure range does the system experience?
Note: Select pressure settings that fall within the middle 80% of the pressure range. The pressure
applied during a normal cycle should never exceed the maximum range value listed for the switch.
Pressure surges should be less than the maximum allowable pressure listed for the switch.

See the modication table on page 8/91 for available modications for 9012 and 9016G
pressure switches. (Form designations are added to the end of the part number of the standard
device for these products.) Some examples are:
• Pilot light
• Prewired receptacles
• External range adjustment
• Range scale window
• Special factory pressure settings
• Pressure connections
When switches must be factory set and only one setting is identied, specify whether this setting
is on rising or falling pressure. See “Special factory setting specied (If indicating only one
special setting, specify whether this setting is on increasing or decreasing pressure.)” in the
modication table on page 8/91.
11. System response time
• If system response time is critical, select a switch with a volumetric displacement that is
compatible with the overall system. See the table below .

Terminology
Measuring range
The measuring range (MR) of a pressure sensor corresponds to the difference
between the upper and lower values measured by the load cell. It ranges between 0
and the pressure corresponding to the size of the sensor.
Operating range
The operating range of a pressure transmitter corresponds to its measuring
range. Within this range, its analog output signal varies between 4 and 20 mA or 0
and 10 V, and is proportional to the measured pressure.
The operating range of a pressure or vacuum switch is the difference between
the values of the minimum low setpoint (PB) and the maximum high setpoint (PH).
Precision
This includes linearity, hysteresis, repeat accuracy, and setting tolerances. It is
expressed as a percentage of the measuring range of the load cell (%MR).
The linearity is the maximum deviation
between the real transmitted curve and
the ideal curve.
The hysteresis is the maximum
deviation between the rising pressure
curve and the falling pressure curve.
The repeat accuracy is the maximum
drift encountered at varying pressures
under given conditions.
The setting tolerances are the
manufacturer's tolerances with regard
to the zero point and sensitivity
(gradient of output signal curve from
pressure transmitter).
Temperature drift
The precision of a pressure sensor is susceptible to variation due to the operating
temperature.
Zero point drift, proportional to the
temperature, is expressed as %MR/°C.
Sensitivity drift, proportional to the
temperature, is expressed as %MR/°C.

Terminology (continued)
Switching point on rising pressure (PH)
This is the upper pressure setting at which the output of the electronic pressure or
vacuum switch changes state on rising pressure.
Switching point on falling pressure (PB)
This is the lower pressure setting at which the output of the electronic pressure or
vacuum switch changes state on falling pressure.
Differential
This is the difference between the switching point on rising pressure (PH) and the
switching point on falling pressure (PB). The low point can be set at the values
indicated on the operating curves shown on the product pages.
Switches with xed differential
Depending on the switch, either the high or low operating point is adjustable, and
the other operating point follows. The window is xed.
Switches with adjustable differential
An adjustable differential allows independent setting of both operating points.
Spread
For dual-stage switches, the spread indicates the difference between the two
operating points on rising pressure (PH2 and PH1) and, for vacuum switches, the
difference between the two operating points on falling pressure (PB2 and PB1).
Differential-pressure sensing
Switches for differential-pressure sensing measure the difference between two
pressures.
Size
Pressure transmitters and pressure switches
This is the maximum value of the operating range.
Vacuum transmitters and vacuum switches
This is the minimum value of the operating range.

Setting point
Accuracy (switches with setting scale)
The tolerance between the point at which the switch actuates its contacts and the
value indicated on the setting scale. Where very high setting accuracy is required
(initial installation of the product), it is recommended that you use separate
measuring equipment (pressure gauge, etc.).
R
Repeat accuracy
This is the variation in the operating point between several successive operations,
or the tolerance between two consecutive switching operations.
F
Drift (F)
The tolerance of the operating point throughout the entire service life of the switch.

Maximum allowable pressure
The maximum value of an accidental pressure surge of very short duration (a few
milliseconds).
Maximum permissible accidental pressure
This is the maximum pressure (excluding pressure surges) that the sensor can
occasionally withstand without permanent damage.
Maximum allowable pressure per cycle (Ps)
The maximum pressure level per cycle that the switch can withstand for optimum
service life.
Surge
A surge is a high rate of rise in pressure, normally of short duration, caused by
starting a pump or by opening and closing a valve. Depending on frequency and
duration, surge can reduce service life. Extremely high rates of rise in pressure can
be damaging even if they are within the limits of the maximum allowable pressure.
Destruction pressure
Also called burst pressure, the destruction pressure is the pressure value which, if
exceeded, is likely to cause serious damage to the sensor—such as leaking,
bursting, or permanent damage.
Load resistance of pressure transmitters
The supply voltage and load resistance of a pressure transmitter must be selected
according to the following formula:
R load = U supply – U supply min. (U supply min = 11 V for XMLE and 17 V for XMLF)

Function
Pressure and vacuum switches control or regulate pressure or vacuum levels in
hydraulic or pneumatic systems. They transform the pressure change into a digital
electrical signal when the preset operating points are reached.
Switches for control circuits
Switches with control-duty rated electrical contacts, designed for control of
contactors, relays, power valves, PLC inputs, etc.
Switches for power circuits
Switches with power electrical contacts (1, 2, or 3 pole) designed for direct switching
of single-phase or three-phase motors (pumps, compressors, etc.).
Pressure switch operating principle
Fixed Differential: Detection of a Single Threshold
Fixed differential switches have
a single adjustable setting point
(either PH or PB). The
differential between the high
and low points (PH–PB)
depends on the construction of
the switch. It is not adjustable.
–– Adjustable value
--- Nonadjustable value
PH = High point
(on rising pressure)
PB = Low point
(on falling pressure)
Example: Contact
schematics of XMLA
Adjustable Differential: Regulation between Two Thresholds
Adjustable differential switches
have setting points for both the
high point (PH) and the low
point (PB). Both of these points
can be independently adjusted.
–– Adjustable value
PH = High point
(on rising pressure)
PB = Low point
(on falling pressure)
Example: Contact
schematics of XMLB
Dual-Stage: Detection of Two Thresholds
Dual-stage switches allow two distinct levels of control to be monitored with one
device. Each stage allows detection of a single threshold with a single setting point
(xed differential). Both these points can be independently adjusted. However, for
both stages, the differential between the high point and the low point (PH1–PB1 and
PH2–PB2) is xed and depends on the construction of the switch.
–– Adjustable value
--- Nonadjustable value
PH = High point
(on rising pressure)
PB = Low point

Vacuum switch operating principle
Detection of a single threshold
The switches for detection of a single threshold (xed differential) have a single
adjustable setting point (PH). The differential between the high and low points (PH–
PB) depends on the inherent characteristics of the switch. It is not adjustable.
–– Adjustable value
--- Nonadjustable value
PH = High point
PB = Low point
Example: Contact
schematics of XMLA
Regulation between two thresholds
The switches for regulation between two thresholds (adjustable differential) have
both a high point setting (PH) and a low point setting (PB). Both of these points can
be independently adjusted.
–– Adjustable value
PH = High point
PB = Low point
Example: Contact
schematics of XMLB
Detection of two thresholds
The dual-stage switches, for detection at each threshold, have an adjustable high
point setting for each stage (PH1 and PH2). Both of these points can be
independently adjusted.
For both stages, the differential between the high point and the low point (PH1–PB1 and
PH2–PB2) depends on the inherent characteristics of the switch. It is not adjustable.
–– Adjustable value
--- Nonadjustable value
PH = High point
PB = Low point
Example: Contact schematics of XMLD
Maximum allowable accidental pressure
The maximum accidental pressure of XML switches is equal to at least 2.25 times
the switch size.
If accidental overpressures occur and their duration is less than 50 milliseconds, the
pressure damping device incorporated in the XML switches (sizes 10 bar and
greater) reduces the effect.

Selecting the switch size
After establishing the type of switch required for the application (single threshold
detection or regulation between two thresholds), the selection of its size depends on
the following criteria:
b the differential: difference between the high point (PH) and the low point (PB),
b the maximum pressure allowable per cycle,
b repeat accuracy, precision and minimum drift.
Selecting a xed differential pressure switch for detecting a
single threshold
Main criterion: minimum differential
Example: for a selected high point (PH) of 7 bar
XMLA010•••••
Differential = 0.5 bar
XMLA020•••••
Differential = 1 bar
XMLA035•••••
Differential = 2 bar
Select an XMLA010••••• (the lowest size)
Main criterion: tolerance to overpressures
Example: for a selected high point (PH) of 12 bar
XMLA020•••••
Allowable accidental overpressure = 45 bar
XMLA035•••••
Allowable accidental overpressure = 80 bar
Select an XMLA035••••• (the highest size)
Main criterion: repeat accuracy, precision and minimum drift
Example: for a selected high point (PH) of 18 bar
As a general rule,
avoid working at
the upper or lower
limits of the
operating range.

The difference between the operating

for each stage. This point is not adjustable,
so the value of the differential is xed. It is
the inherent differential of the switch
(contact differential, friction, etc.) for each

Example:
stage 1 =

For stage 2 (segment GH):
Operating point on rising pressure (PH2) is
20 bar (set value at which contact 2

Application and general information
9012 pressure switches can generally be used in any application where electrical
contacts must open or close in response to a system pressure change, within the
electrical and pressure ratings of the switch. Pressure switches are used in a wide
variety of applications such as the following:
b compressed air systems b stamping presses
b HVAC equipment b automatic grinders
b chillers b welders
b pumping systems b process equipment
b machine tools b molding machines
Pressure switches typically perform one of the following two functions:
Monitoring the pressure in the system. The switch can be used either as an interlock
that sequences operations in an automatic system, or to give an audio or visual
signal, typically an alarm of an undesired condition, at predetermined pressures. A
switch with a xed differential is generally used in these applications.
Controlling the pressure in the system by starting and stopping a pump or a
compressor at predetermined pressures. A switch with an adjustable differential is
usually needed in these applications.

Diaphragm life
The elastomer diaphragms used on 9012G switches can withstand high speed
cycling and wide pressure changes. They can tolerate operating speeds up to 200
cycles per minute with no negative impact on the life of the diaphragm.
Diaphragm life is affected by pressure medium compatibility. Standard diaphragms
on 9012G devices are nitrile in zinc-plated steel anges. Also available are Viton
uorocarbon and ethylene propylene diaphragms, as well as Type 316 stainless
steel anges.
The diaphragm can withstand wide pressure changes on each operating cycle.
However, the pressure applied to the diaphragm during the normal operating cycle
should never exceed the maximum value listed in the Range column in the catalog
listing. Regularly cycling the pressure above this value reduces life considerably. If
signicant surges are common, or if pressures are higher than those listed in the
Range column, consider using a piston device.
Piston life
For long piston life, the pressure medium should be ltered to keep foreign matter
such as dirt and chips out of the piston assembly. 9012G sealed piston devices are
not recommended for use on dry gas media, since this usage could cause some
leakage past the seal. Depending on the gas, the media pressure, and the rate of
operation, the amount of leakage could render the switch inoperable. (Note,
however, that some weepage of the media is necessary to lubricate the seals. This
small amount of weepage does not indicate a problem.)
Surges
One of the most destructive conditions for a pressure switch is hydraulic surge. A
surge is a high rate of rise in pressure, normally of short duration, caused by starting
a pump or by opening and closing a valve. Extremely high rates of rise in pressure
can be damaging even if they are within the limits of the maximum allowable
pressure.
To limit the effect of surges, the switch should be mounted as close to an
accumulator and as far from the pump or quick acting valve as possible. The 9012G
piston-actuated switches have a 0.020 in. pressure orice to help reduce the effects
of minor surges. 9012G diaphragm-actuated switches have a 0.060 in. pressure
orice. A restrictor with a small orice placed in the line between the switch and the
pump or valve will further help to protect the switch. Using a surge snubber such as
the 9049A26 or A26S will also protect the switch.
Vibration
Among other things, excessive vibration can cause contact bounce, chatter, or
premature contact transfer, especially when system pressure is near the operating
point of the switch. Remote mounting of the switch is the best way to avoid problems.
Use on steam
Switches should not be applied directly on steam exceeding 15 psig. However, with
steam capillary tubing installed between the pressure connection and the switch,
steam pressure up to 250 psig can be applied—provided this does not exceed the
maximum allowable pressure rating of the switch or the maximum temperature rating
at the actuator. Refer to the instruction bulletin supplied with the device.
Dual-stage operation
The 9012G dual-stage pressure switches provide two distinct levels of control from
one device. These switches are most commonly used where dual functions are
required, or in sequencing applications such as alarm-shutdowns.
Differential-pressure operation
The 9012G pressure switches for differential-pressure sensing can monitor changes
in the difference between two pressures. These unidirectional devices signal that a
predetermined pressure difference was reached, resulting from a widening or
narrowing of the difference between two pressures.

Piston- vs. diaphragm-actuated devices
Whether to select a piston or diaphragm device depends on several criteria:
b maximum allowable pressure
b range and differential
b surges
b medium (whether hydraulic or pneumatic)
Maximum allowable pressures for piston devices are much higher than for
diaphragm devices. Most diaphragm devices have a maximum allowable pressure of
850 psi or less, whereas all piston devices have a maximum allowable pressure of
10,000 psi or more.
Range and differential for diaphragm devices are lower than for piston devices.
Many applications call for a low differential, such as 20 psi. This may exclude piston
devices, which have a minimum differential of 60 psi or more.
Surges are a part of every hydraulic system. While many are small and have only a
small effect on the switch, some are signicant and can potentially destroy a
pressure switch. Diaphragm devices are the most sensitive to surges and are most
easily damaged. Piston devices are more tolerant of surges and last longer in the
same application.
Hydraulic systems, which typically use oil-based media, are more demanding
applications than pneumatic systems. Pressure switches used in hydraulic
applications typically experience higher pressures, have wider pressure variations,
and produce more surges, since the medium does not compress. Pneumatic
systems, which typically use air, place fewer demands on a system, since these
applications typically experience lower pressures and the medium can compress,
cushioning the effects of surges. Table 1 offers basic guidelines for determining the
selection of a piston- versus a diaphragm-operated pressure switch.

Operating points (set points)
Pressure switches have two operating points:
b Increasing pressure (rising pressure)
b Decreasing pressure (falling pressure)
These operating points are also called the set points of the switch.
Differential
The differential is the difference in pressure between the rising and falling pressure
points. It can be adjustable or xed.
Range
The range refers to the pressure limits within which the operating points (settings)
can be adjusted. The range of the 9012G pressure switch is tied to the decreasing
pressure operating point. Adding the differential to the decreasing pressure
operating point determines the increasing pressure operating point.

Differential
Fixed differential
To determine the operating range on rising pressure for a xed differential switch,
add the differential to the decreasing pressure operating point. For example, to
determine the range on increasing pressure for a 9012GDW5 switch:
b Range on decreasing pressure = 3 to 150 psi
b Fixed differential = 6.0 ± 0.8 psi
b Range on increasing pressure = 9 ± 0.8 to 156 ± 0.8 psi
Adjustable differential
For adjustable differential switches, add the minimum differential to the low end of
the range and the maximum differential to the high end of the range. For example, to
determine the range on increasing pressure for a 9012GAW5:
b Range on decreasing pressure = 3 to 150 psi
b Adjustable differential = 6.0 to 30 psi
b Range on increasing pressure = 9 to 180
During the normal operating cycle, system pressure should never exceed the upper
limit of the range when using a diaphragm-actuated switch. This greatly reduces the
life of the diaphragm. For optimum life, operate the switch in the middle 80% of the
range.
Maximum allowable pressure
Maximum allowable pressure is the pressure to which a switch can be subjected
without causing a change in operating characteristics, shift in settings, or damage
to the device.
System pressure surges may occur during machine startup or from valve operation.
Surges are not normally detrimental to the life of a switch if the surge is within the
maximum allowable pressure rating of the switch. Diaphragm-actuated switches
should not be subjected to more than 10 surges per day. More frequent surges
greatly reduce the life of the diaphragm.

Differential-Pressure Operation
Pressure switches for differential-pressure operation are used to monitor the change in the difference between
two pressures. The 9012G differential-pressure switches are unidirectional devices and are used in applications to
signal that a predetermined pressure difference has been reached as a result of a widening or increasing difference
between the two pressures. They can also be used in applications to signal that a predetermined pressure
difference has been reached as a result of a narrowing or decreasing difference between the two pressures.
NEMA 4, 4X, and 13 devices are suitable for use in Class I, Division 2, Groups A, B, C, and D hazardous locations
or nonhazardous locations only.

Dual-Stage Operation
The 9012G dual-stage pressure switches are designed for use in applications where two separate pressure
operations must be controlled by a single pressure monitoring device. These controls are most commonly used
where dual functions are required or in sequencing applications such as alarm shutdowns. The spread between
the two stages is adjustable, but the differential between the high (rising) and low (falling) operating points of each
stage is xed.
NEMA 4, 4X, and 13 devices are suitable for use in Class I, Division 2, Groups A, B, C, and D hazardous locations
or nonhazardous locations only.

9016GAW Switches for Sensitive Control Applications
9016GAW vacuum switches have double throw contacts. Normally open and normally closed circuits allow the
use of these controls for standard or reverse action applications.
Standard controls can be mounted from the front using the bracket provided. Two mounting screws are required for
rm attachment to any smooth, at surface. Allowance must be made for ange projection.
Controls with the Form F modication include two mounting feet with 9/32” mounting holes on 3–3/4 in. centers.
The Range and Differential adjustments are accessed by removing the front cover.
■ Maximum allowable positive pressure: 100 psig.
■ Diaphragms are oil resisting, nitrile butadiene rubber (Buna-N).
■ For electrical ratings and temperature limitations, see table on page 8/83.
■ For dimensions and modications, see page 99.
