Temperature and Heat Control Devices

A temperature controller (heat controller) is a device that compares the temperature read from a probe with the setpoint and switches a heater or cooler on and off; it is selected by sensor input type, on-off or PID operating mode, output type, supply voltage and housing dimension. It is used to hold process temperature at the setpoint in plastic and packaging machines, industrial ovens and cooling systems, and to adjust room and fan coil temperature in buildings. The subgroups include analog-adjustable devices, digital devices operating on-off and PID, and humidity and temperature controllers; Siemens room and fan coil thermostats are listed directly on this page. Panel-mount devices are available from GEMO, Enda and Tense in housings such as 48x48 mm, 72x72 mm and 96x96 mm, and room thermostats are available in surface-mounted and flush-mounted versions. On-off models are preferred for jobs where oscillation around the setpoint is acceptable, and PID models for processes with narrow tolerances. Probes that match the sensor input of the device are in the Temperature Probes category.

How to choose Temperature and Heat Control Devices

A temperature controller (heat controller) is a device that compares the temperature read from a probe with the setpoint and switches a heater or cooler on and off; it is selected by sensor input type, on-off or PID operating mode, output type, supply voltage and housing dimension. It is used to hold process temperature at the setpoint in plastic and packaging machines, industrial ovens and cooling systems, and to adjust room and fan coil temperature in buildings.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
