Level controllers monitor, regulate, and control liquid or solid levels in a process. There are three basic types of control functions that level controllers can use. Limit control works by interrupting power through a load circuit when the level exceeds or falls below the limit set point. A limit controller can protect equipment and people when it is correctly installed with its own power supply, power lines, switch and sensor. Advanced or non-linear control includes dead-time compensation, lead/lag, adaptive gain, neural networks, and fuzzy logic. Level controllers can be used for either liquid or powder or other dry material applications.

Humidity Controllers
Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms.
pH Controllers
pH and ORP controllers monitor and can control the pH (acidity or alkalinity) and/or the ORP (oxidation reduction potential) of liquids involved in a testing or process application.
Pressure Controllers
Pressure controllers accept input from pressure sensors, transmitters, gauges, and other devices and subsequently control adjustment to the pressure to maintain or achieve the desired pressure level.
Temperature Controllers
Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level.
Universal Process Controllers
Universal process controllers constitute a broad area of control devices that may be employed in the monitoring and control of many different process variables, including temperature, pressure, flow and other values.
Web Controllers
Web controllers maintain control functionality over processes with web or sheet rollers.  Control functionality includes maintaining tension of the web, centering on the track, and material feed rates.
