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, and the measured resistance value is greater than 20MΩ were qualified. Or 250V shake table measuring thermal resistance between the resistance of each pole and greater than 20MΩ. In making the shake table to measure are forbidden to access both ends of the poles on both sides of the thermal resistance shake table to avoid breakdown RTD Pt100 RTD retail, the thermal resistance is damaged. 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 Pt100 RTD distribution, 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 fine wire bifilar Shanghai Automation Instrumentation force measured on an insulating material made of skeleton made of | Pt100 RTD Business | Guangdong Pt100 thermal resistance provided by the Shanghai Automation Instrumentation Co., force measurement. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) located in Zhabei District Luochuan Road 638. Scraps and development in the wave of market economy, the current force measurement since the instrument has a high profile in the flow meter, and enjoys a good reputation. Force measurement instrument made from the entire network business alliance certification, marking our service and management level has reached a new height. Force measurement instrument from the staff willing to work with all people of insight and common development, for a better future.
