PID Thermostats

A PID thermostat is a digital temperature controller that continuously adjusts the power delivered to the heater by responding to the difference between the measured temperature and the setpoint with proportional, integral and derivative calculations. It is used in processes where temperature must be held within a narrow tolerance, such as plastic machines, industrial ovens and packaging systems. In this category, GEMO, Enda, Tense and GMT devices are available in housings such as 48x48 mm, 72x72 mm and 96x96 mm, with J, K, S, R, T type thermocouple and PT100 inputs and relay or SSR outputs; models with a built-in timer relay and step-programmed models are also available. Select a PID temperature controller by sensor input type, relay or SSR output, supply voltage, housing dimension and RS485 Modbus need. Models with auto-tune calculate the PID parameters automatically; models with an SSR output do not switch the load directly, they drive an external solid state relay. A standard PID thermostat is not a profile controller; it holds a single fixed setpoint, and a step-programmed model or a profile controller is needed for a ramp and soak program.

How to choose PID Thermostats

A PID thermostat is a digital temperature controller that continuously adjusts the power delivered to the heater by responding to the difference between the measured temperature and the setpoint with proportional, integral and derivative calculations. It is used in processes where temperature must be held within a narrow tolerance, such as plastic machines, industrial ovens and packaging systems.

  • 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.
