1, the working principle of heat resistance of almost all of the conductor and semiconductor resistivity are temperature changes with its own change, and there is a certain value, this physical phenomenon is called "thermal resistance effect." If we can find or have known thermal resistor temperature change of correspondence between the electricity can be measured by measuring the resistance value of the instrument, the purpose of measuring the temperature. Using the temperature measuring element made of this principle is called thermal resistance or thermistor, RTD is uniformly thin metal wire double wound RTD on the skeleton made of insulating material is made of the temperature change converted into a resistance change element of wear thermal resistance quote, usually leads to resistance signal is transmitted to the computer control means or by other primary instrument. Installation of industrial thermal resistance at the production site, there is a certain distance between the control room and, therefore thermal resistance leads have greater influence on the measurement results. Guangxi wear thermal resistance, Shanghai Automation Instrumentation force measurement, wear thermal resistance retail force measured by the Shanghai Automation Instrumentation Co., Ltd. "Industrial thermocouple, RTD, transmitters, flowmeters, intelligent instruments, actuators' preferred measure of the Shanghai Automation Instrumentation Co., Ltd. (www.licesh.com), the company is located: Zhabei District, Shanghai Luochuan Road 638 No, for many years, since the force measuring instrument to provide customers with the best quality service, contact: Hua powder. Welcome to the new and old customers call, letter, visit the guide, business negotiations. Force measurement since the instrument expect to be your long-term partner!
