Process Controllers
Process Controllers
Process controllers, or PID controllers, are electronic devices used to measure a process variable and make adjustments to keep that variable within a set range or at a desired setpoint. Controllers are used in industry to regulate temperature, pressure, force, flow rate and much more.

Process controllers use embedded software and a wide variety of functions to make precise adjustments using advanced feedback control. PIDs continuously take measurements from sensors and make adjustments to the final control element to maintain the desired setpoint. Alarms notify operators of any undesired measurements or results.

Most controllers also have a display, and can provide display parameters based on hardware configuration, masking irrelevant parameters if necessary. This way, operators only need to adjust the setpoint and alarm, then launch self-tune.

PXU PID Controllers Series Image
Red Lion's PXU line of PID controllers is the perfect solution for your basic control requirements. The PXUís capabilities cover applications requiring simple on/off control all the way to full PID control. Featuring one of the industryís largest displays, the PXU is easy to read from a distance. Available in various sizes, 1/16, 1/8 and 1/4 DIN and packaged in a space saving design, the PXU can be installed into enclosures with a reduced depth to save space and money.
The PXU offers a dual line display with four digits on each line. Status indication of alarms, control, and temperature enhance the display functionality. The front panel provides IP65 protection.
One of the outstanding features of the PXU is the universal input capability which allows them to operate with pressure transducers, flow meters, current transducers, RTDs and thermocouples. Input selection is easy using the front panel push-buttons, or Red Lionís Crimsonģ 2 software.
Programming the PXU is easy using the RS-485 communication option. Using the award-winning Crimson 2 software, simple check boxes or numerical entries makes short work of programming multiple units. In addition to programming, the RS-485 port can also be used to collect the process values from the PXU and remotely display that information.
The PXU offers alarms and may be configured to suit a variety of control and alarm requirements. From its large display to the universal input the PXU is the perfect solution for your next control requirement.
