thermocouple is one part of gas safety protection system .
1) Electric potential:(600~650°C)≥8 mV
2) Resistance(room temperature):setting value ±15%
3) Principle of opeartion:Thermocouple with temperature switches internal, In the working such as the gas oven non-working area temperature more than temperature switches rated temperature, at this time temperature switches will automatically cut off power supply, to have safety protection.
