About Temperature Controllers

Temperature controllers accept inputs from temperature sensors or thermometers, and output a control signal to keep the temperature at the desired level. Temperature controllers use several different control techniques. Limit control establishes set points that, when reached, sends a signal to stop or start a process variable. Linear control matches a variable input signal with a correspondingly variable control signal. Feedforward control does not require a sensor and provides direct control-compensation from the reference signal. Proportional, integral and derivative (PID) control requires real-time system feedback. PID control monitors the error between the desired variable value and the actual value, and adjusts the control accordingly. Fuzzy logic is a control technique in which variables can have imprecise values (as in partial truth) rather than a binary status (completely true or completely false). Temperature controllers that use advanced or non-linear controls such as neural networking, adaptive gain, or emerging algorithms are also available.  


Products & Services Related to Temperature Controllers
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.
Flow Controllers
Flow controllers monitor and maintain proper humidity levels in environmental test applications, or in other areas such as food storage or electronic room regulation.
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 Industrial Process Controllers
Specialty industrial process controllers are used in unlisted, specialized or proprietary applications.
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.
