Introducing our range of universal thermocouples, 30MV 60 SEC. They are used for sensing the temperature of gas pilot burners and are used in conjunction with ignitors.
What and how are gas thermocouples used?
Gas thermocouples are a safety device; they will only allow the main gas valve to open if it detects a millivolt signal. This is done with the sensor tip getting hot via a pilot flame. The millivolt signal caused the magnetic plunger to energise open to allow gas flow when this gets hot.
