What Is a Process Control System And Its Types Including Eurotherm 3200

Primarily a process control system watches over the manufacturing environment and controls the process or flow electronically on the basis of various set-points fetched by the user. The devices used in a process control system are known as programmable logic controllers. It can be used for controlling machines with discrete parts such as motor starters, limit switches etc. If you wish to keep a check on analog devices, distributed control systems are considered as the front runners.

These controllers can be divided into 2 basic categories:
1.Single Loop Controllers
2.Multi-Loop controllers

Single loop controllers find major usage in many industrial establishments like power plants, oil refineries, chemical plants, petrochemical plants, and more. Basically, a single loop controller obtains crucial parameters like temperature, flow rate, pressure, temperature from sensors and transmits corresponding instructions to control elements like valves for further maintenance. Single loop controllers are extensively used in the industry these days to control small plant facilities and serve as back-ups to distributed control systems.

When there is more than one control loop within a system, multi-loop controllers are used. Generally mounted on panels these controllers are programmed using a typical proprietary software program that downloads settings to the multi-loop temperature controller using communications.

Once you’ve understood the process controllers in entirety, you can look online to purchase top-grade process controllers like 3208 Eurotherm, Eurotherm Efit, Eurotherm 3200 that suit your requirements.

Eurotherm 2132i and 2704: The Highlights

Using a Eurotherm temperature controller works wonderfully when you have to stabilize the heat in a system, after a target temperature has been finalized. Though all of these devices follow either the open-loop control or a closed-loop control, there are certain features that are unique for every individual model. And that is what makes these devices ideal for a variety of places and purposes. The mechanism for each model differs so that one can pick those that are best suited for the target purpose.
Eurotherm 2132i:
This is basically a combined alarm and indicator unit measuring 48x24x103 mm. It ensures a very accurate indication and alarming of temperature and process measurement. There is a universal input system supported by a total of three alarm set points, 1 logic output/input and 2 relay output systems. Besides, it also has a customizable operator interface.
Eurotherm 2704:
This model measures 96x96x150 mm and has a dot matrix display. The design is modular which means that it has good 5 I/O slots. Apart from that, it supports the order of up to three loops. It is ideal for use in digital communications and programming. This is a very advanced controller that works at a convenient supply voltage which can be chosen as per the requirement.

Some Recognized Features Of Eurotherm 2416

Eurotherm 2416 is a versatile temperature controller, known for its high stability and self adaptive tuning in a 1/16 DIN size (48x48x150mm). The 2416 features a modular hardware construction that can accept up to three plug-in I/O modules and one communication module. Fully configurable on-site, these controllers can be availed in versions with a simple 8 segment setpoint profile. They are also available in more powerful versions to run one 16 segment program or store 4 programs of 16 segments. Below are some of the additional features of Eurotherm 2416:

Precise control

An advanced PID control algorithm ensures stable ‘Straight-line’ control of the process. A one-shot tuner does both sets up the initial PID values and calculates the overshoot inhibition parameters. Moreover, an adaptive tuner is provided to handle process with continually changing characteristics.

Customised operation

The process value and set point are visible on a custom LED display. Tactile push buttons are added to ensure positive operation. Access to other parameters is easy to understand, and can also be customized to display only those parameters that need to be adjusted. You can also lock other parameters under password protection. A front panel auto/manual button is also provided to ease the functionality.

Digital communications

Eurotherm 2416 comes with either EIA485 2 wire or 4 wire or EIA232. It is also available with industry-standard protocols, including Modbus®, Eurotherm Bisync, and SPI.
