Gas boiler parts temperature sensor thermocouple B2204A thermocouple is an electrical device consisting of two different conductors forming electrical junctions at differing temperatures. A thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type of temperature sensor.Thermocouples are used in homes, offices and businesses as the temperature sensors in thermostats, and also as flame sensors in safety devices for gas-powered major appliances.Product DescriptionNameGas boiler parts temperature sensor thermocoupleModelB2204BrandBngasCable materialCopperLength600mm, 900mm, 1200mm or customizedVoltage≥30mvFixing methodScrewedTechnology parameter(1) Thermal potentialHeat characters: the temperature of thermocouple on flame is 600-700 and the heat potential should≥15mvCool characters: the temperature of thermocouple on flame is 600-700. The heat potential should be≤1.5mv when 1.5min if it heated for 5min and then cut off the power.Work temperature: the top temperature is lower than 700 and the other parts higher than 125(2) Inner resistanceAccording to its type and length and the tolerance is in ±10% as is requested.
