Thermal resistance is not only widely used in industrial temperature measurement three-wire RTD wholesale, and was made standard benchmark instrument. However, due to the temperature range of his making his application subject to certain restrictions, the thermal resistance measurement principle is based on the resistance value of the conductor or semiconductor changes with temperature change characteristics. The advantages are many, you can also remote electrical three-wire RTD prices, high sensitivity, stability and strong three-wire RTD, interchangeability and accuracy are better, but the need for power motivation, not able to measure the instantaneous change in temperature . RTD and thermocouple choose the biggest difference is the temperature range of choices, low thermal resistance is a measure of the temperature sensor to measure the temperature is generally -200 ~ 800 ℃, which is a measure of the high temperature thermocouple temperature sensor three-wire RTD retail generally measure the temperature at 400 ~ 1800 ℃, the choice if you measure the temperature at about 200 ℃ thermal resistance measurement should be selected, if the measured temperature at 600 ℃ should choose K-type thermocouple, if the measured temperature at 1200 ~ 1600 ℃ on should choose S-type or B-type thermocouple. Three-wire RTD supply, Qinghai three-wire RTD, the lowest since the instrument measuring the force provided by the Shanghai Automation Instrumentation Co. measured. 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!
