Thermal resistance is not only widely used in industrial temperature measurement, and is made of 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 three-wire RTD Main, you can also remote electrical sensitivity Middle wire RTD price stability, interchangeability and accuracy are better, but the need for power motivation, not able to measure the instantaneous temperature changes. 4. Acceptance Criteria 4.1 temperature element protection tube with the main device the size of the repair should be checked, it should also make occasional checks, temperature measurement devices should overhaul after acceptance to meet the following criteria. 4.1.1 temperature element should not have cracks, delamination, abrasion, surface should be smooth, wiring resistance markers should be clear, temperature measurement devices should verify eligibility, and there is verification certificate of authenticity. 4.1.2 junction box seals should be intact, not due to thermal resistance of bipolar terminals short circuit conditions. 4.1.3 Terminal screws should be intact three-wire RTD wholesale, threads should not have damage, terminals should be clean, there should be attached to the oxide layer. 4.1.4 overhaul after the temperature element should have equipment signs, signage content should be clear. Three-wire RTD price, the lowest since the instrument measuring force, Zhejiang three-wire RTD measurements provided 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.
