A Wide Variety of Models
Peak hold / bottom hold display
Analog voltage output incorporated
as a standard
Since a linear analog voltage output
(1 to 5 V) is incorporated, the sensor is
ideally suited for real time monitoring or
for remote control in combination with
an analog controller (ultra-compact
digital panel controller CA2 series, or
digital panel controller CA series).

MODE
Confirmation of chip component suction
The light weight type does not disturb
the movement of the suction head,
even if it is mounted close to the head.
Verifying placement of frame
High pressure is attained when the
frame is exactly seated. Hence, the
pressure change when the frame is
exactly placed is detected.
Controlling clamping force
The clamping force can be changed to
suit the workpiece by controlling the
supplied air pressure.
Detecting tap breakage
Two opposed nozzles are supplied air at
different pressures. If the tap breaks, the
pressure at the lower pressure side nozzle is
affected by the air of the higher pressure side
nozzle. This change in pressure is detected.
Inspecting orientation of glass sheet
The orientation of the glass sheet can
be recognized by detecting the change
in vacuum due to presence / absence
of indentation.
Controlling edge of winding film
With bifurcated nozzles placed on both sides
of the film, the position of the winding film is
recognized as right-shifted (high pressure),
OK (middle pressure), or left-shifted (low
pressure).

The peak value or the bottom value of
the varying pressure can be displayed.
This function is convenient for finding the
pressure variation range or for deter-
mining a reference for pressure settings.
Analog bar display
Pressure changes can also be dis-
played in an analog fashion using LED
bars. Hence, sudden pressure changes
can be recognized at a glance.
LED bars indicate the pressure level in steps
of 10 % F.S., regardless of the pressure unit.

• This product is not a safety sensor. Its use is not
intended or designed to protect life and prevent
body injury or property damage from dangerous
parts of machinery. It is a normal pressure
detection sensor.
•
The DP2 series is designed for use with non-
corrosive gas. It cannot be used with liquid or cor-
rosive gas.
•The DP2 series is a CE conformity product complying with
EMC Directive. The harmonized standard with regard to
immunity that applies to this product is EN 61000-6-2
(Note) and the following condition must be met to conform
to that standard.
Conditions in use for CE conformity
Condition
• If setting is impossible even with pressing the MODE key,
verify whether the key-protect function is enabled. Please
note that pressing down on the MODE key for an
extended moment will enable the key-protect function as
soon as the key is released.
• If using the window comparator mode, set the pressure
value so that there is a difference of 3 digits, or more,
between Set Value 1 (P-1) and Set Value 2 (P-2). No
output will be possible with a 0 to 2 digit difference.
Operation
Wiring
The analog voltage output does not incorporate a short-
circuit protection circuit. Do not directly connect a power
supply or a capacitive load.
•Make sure that the power supply is off while wiring.
•Verify that the supply voltage variation is within the rating.
•If power is supplied from a commercial switching regulator,
ensure that the frame ground (F.G.) terminal of the power
supply is connected to an actual ground.
•In case noise generating equipment (switching regulator,
inverter motor, etc.) is used in the vicinity of this sensor,
connect the frame ground (F.G.) terminal of the equipment
to an actual ground.
•Do not run the wires together with high-voltage lines or
power lines or put them in the same raceway. This can
cause malfunction due to induction.
•
The sensor should be connected less than 10 m 32.808 ft
from the power supply.
Note: The EN 50082-2 that previously applied to the products for conforming to
EMC Directive was replaced by EN 61000-6-2 starting April 1st, 2002.

•In the Set Value 1, 2 modes, pressing
the key changes the set value to the
low pressure side in case of positive

vacuum side in case of vacuum pres-
sure type sensor.
•
In the sensing mode, if the key is
pressed continuously for 4 sec. or more,
the display shows bottom hold value.
•Each press of the key changes the selected
mode to sensing mode, Set Value 1 (P-1) set
mode and Set Value 2 (P-2) set mode.
•In the sensing mode, if the key is pressed
continuously for about 3 sec., key-protect can
be set / released.
•In the sensing mode, if the mode selection
key is pressed while pressing the increment
key ( ), the initial setting mode is obtained.
In the sensing mode, if both the keys are pressed
simultaneously, zero-point adjustment is done.

Conversion procedure
Conversion table for pressure units
Conversion of pressure units
•In the DP2 series, the conversion
to different units is automatically
done on changing the setting of
the pressure unit. However, this
conversion can also be obtained
by multiplying the values by the
coefficients given in the table on
the right.
•
For example, if 2 kPa is to be expressed
in kgf/cm
2
,
since 1 kPa1.01972102 kgf/cm2,
2 kPa becomes
21.01972102c0.020 kgf/cm2.
Setting of key-protect
Key-protect function
• Key-protect is a function which prevents any unintentional
change in the conditions which have been entered in each
setting mode by making the sensor not to respond to the
key operations.
• In the sensing mode, press key continuously
for about 3 sec. and release it immediately when
is displayed.
• Key-protect is set and the sensor returns to the
sensing mode.
MODE
Others
• Use within the rated pressure range.
• Do not apply pressure exceeding the pressure with-
standability value. The diaphragm will get damaged and
correct operation shall not be maintained.
• Do not use during the initial transient time (0.5 sec.) after
the power supply is switched on.
• Avoid use of standard type, flat type and light weight type
of sensors in places where steam and dust is excessive.
• Take care that the sensor does not come in direct contact
with water, oil, grease, or organic solvents, such as,
thinner, etc.
• Do not insert wires, etc., into the pressure port. The
diaphragm will get damaged and correct operation shall
not be maintained.
• Do not operate the keys with pointed or sharp objects.

PRECAUTIONS FOR PROPER USE
Setting of pressure lead direction
•The pressure lead direction can be changed by
dismantling the pressure port attachment and changing
the mounting direction. The tightening torque of the
hexagon-socket-head bolt (length: 9 mm 0.354 in or less)
should be 0.29 Nm or less.
Note: Make sure to close any unused pressure port with the hexagon-
socket-head plug supplied as accessory.
Piping
•When connecting a hexagon-socket-head plug or coupling
to the pressure port, hold the hexagonal part of the
pressure port with a 12 mm 0.472 in spanner and make
sure that the tightening torque is 9.8 N m or less. Also, in
order to prevent any leakage, wind a sealing tape on the
coupling when connecting.
However, sealing tape is not required for North American
type (DP2-F) using NPTF
1
/
8
coupling. (Sealing tape is
required if NPT
1
/
8
coupling is used.)

PRECAUTIONS FOR PROPER USE
Piping for pressure measurement inlet port
•When connecting a coupling to the pressure measurement
inlet port, hold the pressure port attachment with a
spanner and make sure that the tightening torque is
9.8 Nm or less. Also, in order to prevent any leakage,
wind a sealing tape on the coupling when connecting.
Piping for atmospheric pressure inlet port
•
If there is a possibility of water
entering into the sensor
enclosure through the atmo-
spheric pressure inlet port,
connect a tube to the atmo-
spheric pressure inlet port
through a M5 coupling and
extend the other end of the
tube to a safe place. In this
case, ensure that this end of
the tube does not get clogged.
Fitting of front cover
•Insert the bosses on the front cover into the guide holes at
the bottom of the pressure port attachment, and push in
the direction of the arrow to fit the hook.
When removing the front cover, release the hook first.
