There are a number of inputs in controllers. The type of the control process will always determine the type of input of sensor that is involved. The common input sensors used in these controllers include resistive thermal devices and thermocouples. Other inputs may include linear ones such as mV and mA. There are a number of thermocouple types that can be used in these controllers, the most common ones include J, K, T, S, R, B and L types.

The use of temperature and process controllers is not limited to one particular industry. Heating and cooling applications need to be controlled in a number of industries, each of whom makes use of these controllers. Some of the common uses of these controllers are in industries such as injection molding machines, plastic extrusion, thermo forming machines, food processing, blood banks, food storage and packaging machines.
