Universal process controllers are general devices used to control one or more aspects of a process.


Understanding Universal Process Controllers

Universal process controllers (UPC) may control one or more variables of a process, including:

Additionally, environmental controllers may control multiple variables, including temperature, pressure, and humidity, to maintain a stable environment for comfort or testing purposes.



For detailed universal process controller specifications, including controller type, form factor, inputs, outputs, and standards compliance, please see the Temperature Controllers Selection Guide.


Related Products & Services

  • Batch Controllers

    Batch controllers maintain the correct size of a discrete batch of process material, such as the volume of a liquid. They are often interfaced with sensors such as load cells, or with volumetric flow meters.

  • Humidity Controllers

    Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms.

  • Level Controllers

    Level controllers monitor, regulate, and control liquid or solid levels in a process.

  • Pump Controllers

    Pump controllers monitor flow and/or level variables, and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off, or more advanced controls for pump speed, output pressure, etc.

  • Specialty Process Controllers

    Specialty industrial process controllers are used in unlisted, specialized or proprietary applications.

  • 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.

  • Web Tension Indicators

    Web tension indicators measure and report tension parameters in web or other flat-sheet production processes. Some types of web tension indicators have control functionality as well.
