High quality gas fireplace temperature sensor thermocouple
Our company manufactures thermocouple for many years.
Thermocouple and magnet valve compose a flameout safety protector which widely used in gas
appliance, such as gas cooker, gas oven, gas stove, gas heater and so on.
There are different styles and sizes. We also can make according to drawings and requests of
Thermocouple and magnetic valve composegas safety protection devices, thermocouple is a
transducercan provide the power, magnetic valve is a controller.
When thermocouple tips is heated by fire, cold and heat generate thermoelectric power due to
temperature difference, to form closed loop current and make magneticvalve actuation,opening
When the flame is out owing to unexpected reasons, thermocouple rapidly lose potential, magnet
valve lose suction under the action of spring, so close gas path, and play a safety protection role.
the heat potential should≥15mv
The heat potential should be≤1.5mv when 1.5min if it heated for 5min and then cut off the power.
according to type and length and the tolerance ±10%
according to request of customers
