WSS double-metal thermometers with thermocouple and temperature transform,transmissionapparatus are the kind of transducer which can display and transmit electric signal temperature on thespot. It can not only indicate the temperature but also transmit the signal of the thermocouple anddouble wire system temperature transform,transmission apparatus. As a newthermometer, it canwidely use in many industries such as metallurgy, petrochemical，electric power, spinnery, foodnational defence，etc    Thermocouple，double-thermometer or temperature transform,transmission apparatus isincorporate    Be fit for perennially work in execrable environment    Remote transmission of the electric signal has high precision and stability. Also it can transmitthe double wire system form way    Improve the antterference performance on the process of long distance transmissionAccuracy Grade: 2.5,1.5 level.Temperature range: -60 °C ~ + 500 °C
