Check the insulation coefficient 2.2 Thermal resistance temperature sensing element 2.2.1 Check the insulation factor must be greater than 20MΩ, were measured using a multimeter power block thermal resistance between the two electrode wiring insulation resistance of the resistor housing Pt100 RTD picture, and the measured resistance values ??greater than 20MΩ qualified. Or 250V shake table measuring thermal resistance between the resistance of each pole and greater than 20MΩ. In the shake table to make measurements on both sides of both ends of the non-polar access Pt100 RTD shake table of thermal resistance, heat resistance in order to avoid breakdown , the heat resistance is damaged. Installation Note 1, the thermal resistance should be vertically mounted in a horizontal or vertical pipe should be installed with a protective casing main Pt100 RTD to facilitate maintenance and replacement. 2, the temperature measuring pipe, the pipe element length should be the center line (namely the protection tube insertion depth should be half the diameter). 3, when the temperature of the moving coil meter installation Pt100 RTD offer, hole size should be appropriate for a nice install. 4, the high temperature areas using high temperature cables or high temperature compensation line. 5. To select a different measuring element depending on the temperature. Select the thermal resistance of less than 400 ℃ general measure temperature. 6, the wiring should be reasonable and beautiful, hands instructed to correct. Gansu Pt100 RTD | Shanghai Automation Instrumentation force measurement | Pt100 RTD force distribution 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!
