The temperature regulator is an essential part of the entire control system, and the entire system must be analyzed to select the appropriate equipment. The following elements should be considered when choosing a regulator:
1. Input sensor type (thermocouple, RTD) and temperature range
2. Required output type (electromechanical relay, SSR or solid state relay, analog output)
3. Necessary regulation algorithm (on and off, proportional, P.I.D.)
4. Number and type of outputs (heat, cool, alarm, limit)
