Temperature sensor in Refrigerators/freezers

Refrigerators and freezers became part of daily life and found space in every house to preserve food and perishables. The refrigerator thermistor is a very critical component that act as mind along with the electronic control system. In cooling chambers, the sensor sends the signals when temperature rises above or go below to the set points and activate/stop the compressor. In an evaporator, the sensor is used to sense the set point again at which the defrost cycle begins thereby controlling the occurrence of frosting of ice on the coils.

Temperature sensor in Refrigerators

So in short the temperature sensor (NTC thermistor) plays a vital role in overall performance of the refrigerator/ freezers; It has to be precise, reliable and fast in response and that’s why Thermosen NTC thermistors are the first preference for global OEM’s.
