Metal heat resistance and temperature resistance value can be expressed in general price armored thermal resistance, i.e., Rt = Rt0 [1 + α (t-t0)] wherein, Rt is the resistance when the temperature t by the following approximate relation; Rt0 corresponding temperature t0 (usually t0 = 0 ℃) resistance value; α is the temperature coefficient. Resistance versus temperature for the semiconductor thermistor Rt = AeB / t where Rt is the resistance when the temperature t; A, B a constant depending on the structure of the semiconductor material. Principle resistance thermometer is the use of a conductor or semiconductor resistance varies with temperature this feature. The main advantage of the thermal resistance thermometers are: high accuracy, reproducibility is good; there is a large measurement range, especially in the low-temperature; Easy to use armored thermal resistance sales in automatic measurement, but also to facilitate long-distance measurement. Similarly, the thermal resistance is also flawed, at high temperature (greater than 850 ℃) measurement accuracy is not good; impatience susceptible to oxidation and corrosion. _ The main armored force measuring thermal resistance since the instrument armored thermal resistance _ armored thermal resistance measured by the Shanghai Automation Instrumentation Co., Ltd .. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) is the Shanghai Zhabei District, flow meters leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Since the force measuring device leadership with the staff warmly welcome all inquiries negotiations to create the force measuring instrument since a better future.
