Select the maximum difference between the thermal resistance of the thermocouple is a temperature range of choices, is a measure of the low temperature heat resistance temperature sensor, the temperature is generally measured in -200 ~ 800 ℃, and the thermocouple is measuring the temperature of the thermal resistance of the temperature sensor waterproof Price generally measure the temperature at 400 ~ 1800 ℃ retail waterproof thermal resistance, the choice if the measured temperature at about 200 ℃ thermal resistance measurement should be selected, if the measured temperature at 600 ℃ should choose K-type thermocouple waterproof thermal resistance, If the measured temperature at 1200 ~ 1600 ℃ should choose S-type or B-type thermocouple. First, the nature of the signal, the thermal resistance is the resistance itself, temperature changes, the resistance of a positive or negative change in resistance; whereas the thermocouple is induced voltage changes, he vary with temperature, although .. all contact Thermometer wholesale waterproof thermal resistance, but they have different temperature range, thermocouples used in the high temperature environment, such as platinum and rhodium platinum and rhodium 30 --- 6 (B type) measurement range of 300 degrees ~ 1600 degrees, short-term can be measured 1800 degrees. Waterproof thermal resistance retail _ _ waterproof thermal resistance force measuring instrument lowest since the force measured by Shanghai Automation Instrumentation Co., Ltd .. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) strong, credible, in Shanghai Zhabei District, flow meters and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the force measured since the instrument into the brilliant and you work for a better future!
