Single Loop Controllers

If a system requires a single control loop or discrete devices then a single loop controller can be used to control a thermal or process machine. These instruments can range from the very basic - single, manual, setpoint changes, through to sophisticated profilers which have the capability to execute multiple setpoint changes over a specified period of time.

Single-loop controllers are also often referred to as front-of-panel (FTP) controllers. These controllers provide a clear display on the front of the controller which is used to set up the controller and make program changes.

Multi Loop Controllers

Multi-loop controllers are generally mounted behind the panel and programmed using a proprietary software program on a PC which downloads settings to the multi-loop temperature controller.

Using a multi-loop controller rather than multiple single loop controllers can have many benefits such as reduced installation costs due to having one common connection point, resulting in less wiring and minimizing panel cut outs. Another advantage is controllers can be changed without powering down the system. This process, known as hot-swapping, significantly reduces machine downtime.

Limit Controllers

Limit devices are used in process control applications where independent limit switching for over or under temperature is required. If the pre-set temperature limit is exceeded then the output switches to shut down the system.

A limit controller is often used in conjunction with a loop controller. It will generally accept a variety of inputs such as thermocouple, RTD, or process inputs, then allowing for high or low temperature inputs to be set. Limit controllers are used in a variety of applications, particularly industrial ovens and furnaces applications as well as by the life science industry.

Process Indicators

The range of indicators provided by West Control Solutions can be used to display temperature as well as other process information such as pressure, flow and humidity.

The indicators are available in a variety of panel format sizes. Most application requirements can be met by the flexible options available. All indicators in the West Control Solutions range have UL approval.

Some indicators can also retransmit current process data to other field devices.
