Prompt, accurate flow detection rate and response
Case Study
2400 series Feedforward control is excellent for chemical dosing
applications
Customer Challenge
The 2400 process controller is very suitable in the treatment of waste water,
petrochemical processes and other additive dosing applications because any
possible disturbance to the levels of chemicals added are detected before they can
affect the ongoing process.
Solution
Feedforward is a method for detecting disturbances in the upstream flow and
forwarding this information to the controller so that it can change the output before
the disturbance affects the downstream ratio.
So, in the diagram shown, the upstream flow rate from the flow meter (FT) forces an
immediate change to the output of the controller (OP) and so causes an immediate
change in the Dosing Pump speed.
This Feedforward method is ideal for any process that is subject to upstream
disturbances. This type of disturbance is invariably found in either liquid or gas
systems.
Customer Benefits
• Feedforward control can avoid the slowness of integral feedback control because
the disturbances are measured and accounted for before they have time to affect
• The dosing rate immediately tracks any changes in flow rate and so prevents any
possibility of over or under dosing
Typical use of technology
• Liquid Level - Boiler Drum Level
• Chemical Dosing - Paint Mixing, Brewing,
• Industrial Distillation – Brewing, Petroleum Refineries, Petrochemical, Chemical
Plants, and Natural Gas Processing Plants.

2100 series 5 Mode Timer feature enables cost effective temperature and
process control
Customer Challenges faced in the food beverage industry
Global market forces are driving the continual evolution of the food and beverage
industry. Consolidation, changing consumer preferences and increasing government
regulations are dramatically impacting manufacturing and business strategy. In this
fiercely competitive marketplace, consistent high quality and cost effectiveness are
critical to meet consumer demand.
Solution 2100 Controller
Eurotherm acknowledge these commercial pressures and our products ensure
simple cost effective process control. Even one of our simplest, compact controllers
has useful cost effective features.
The 5 mode timer in the 2100 temperature process controller may be used to
control batch operations, e.g. food production, ovens, sterilisers, fryers. An ideal
application would be single dwell at the end of either a controlled ramp rate or
natural approach to setpoint without the need for an additional timing device.
Available Timer Operation Modes are:
• Dwell and Switch Off
• Time from Cold and Switch Off
• Delayed Switch On
Benefits
• This maintains a target temperature at the end of a ramp rate without the need for
an additional device, thereby simplifying the process
• Easy operation with customised interface that presents only the parameters that
the operator needs to see. All other parameters can be locked away under
password protection.
Typical use of technology
• Small Ovens, Fryers, Sterilisers, Incubators

2400 controller 8 segment program, repeatable and simple to change
Customer Challenges faced in Autoclave and Environmental Chamber applications
Many applications need their process values (i.e. Temperature, Pressure, Flow etc) to
be varied with time.
Amongst other applications Autoclaves are used for Sterilisation and for Vacuum
Forming. In these applications there are invariably a number of ramps, and dwell
times required to ensure that the material has been adequately processed.
In Environmental Chambers programmed profiles are generally run repeatedly for
some time and this is a method that is used to produce accelerated ageing. This
process is therefore very useful for determining the likely longevity of a product
before it fails.
Solution 2400 Controller
• The 2400 series process controller offer setpoint programming as an option. The
program is stored as a series of segments which can be ramps, dwells, steps etc.
• All 2400 programmer/controllers have an 8 segment program as standard, and
can optionally have up to 20 off 16 segment programs each with 8 digital events.
The digital events are used to control other ancillary equipment at pre-
determined segments in the program. For instance; it may switch on a vibration
table at some stage in the process.
• All of these features make the 2400 programmer/controller ideal for Furnaces,
Environmental Chambers, and Autoclave applications.
Customer Benefits
• Minimises the need for extra equipment which becomes costly to install and
maintain, time and space saving
• Offers high integrity, repeatable processing thus increasing yield consistency and
high product quality
Typical use of technology
• Autoclaves – Steam Sterilization of medical, pharmaceutical and laboratory
equipment
• Environmental chambers –test the effects of environmental conditions such as
accelerated aging on industrial products, materials, biological items and
electronic devices
• Industrial furnaces – Heat Treatment, Glass Furnaces, and Lehrs

In 2000 Series controllers it is possible to use the PDS communication link to
send a setpoint from one controller to a network of slave devices - providing
the economical creation of multi-zone temperature control solutions.

Modbus RTU
Modbus Master
The 2000 Series uses industry standard protocols
such as Modbus RTU, DeviceNet or Profibus DP
to communicate with supervisory systems and
PLCs over EIA232, EIA485 (2 wire) or EIA422 (4
wire). This carries the information and overall
control into the supervisory system while
maintaining local access to the local equipment
ensuring overall plant integrity in all situations.
Communication
Sometimes it is desirable to control a process using two separate inputs to
derive the PV (process value). This could be based on a highest wins, lowest
wins, some function of the two inputs, or switching between the two inputs at
some pre-determined point in the process.
For example, an application could consist of a thermocouple for measuring up
to 800°C and a Ratiometric Pyrometer for measuring the range between
700°C and 1,400°C.
Typically when the temperature is below 740°C the thermocouple provides
the PV and, when between 740°C and 780°C the controller switches gently
from the thermocouple to the Pyrometer which provides the PV up to 1,400°C.
Derived inputs
Using Eurotherm setpoint retransmission over PDS
communications it is possible to use two 2400 controllers
as a cascade control system with the output of the first (or
master controller) forming the setpoint of the second (or
slave controller).
Eurotherm advanced algorithms enable the use of either
setpoint or PV feedforward to limit the slave setpoint - for
example ±10% of the master setpoint or PV.
Cascade control
From a simple ramp and dwell to a 16 segment
program with event outputs, the 2000 Series provides a
powerful platform for setpoint profiling. Programs can
be edited from the instrument HMI and for the 2400
instruments, using iTools Setpoint Program Editor.
iTools configuration software enables you to store and
clone controller configurations, as well as commission
your process control system. This facility significantly
reduces installation and commissioning time while
improving the security of the process. The Eurotherm
advanced customer sensor linearisation tool also
provides for the download of special sensor response
characteristics to the controller.
Reduced installation and
commissioning time
Easy setpoint programming
From fixed build to modular construction, the
Eurotherm flexible 2000 Series offers a truly versatile
solution to all your requirements.
