Thermocouple (thermocouple) temperature measurement instruments commonly used in distribution sheathed thermocouple temperature measurement devices, which directly measure the temperature, and the temperature signal is converted into thermal EMF signals by electrical instrument (secondary instrument) into the measured medium temperature. Often due to the shape of various thermocouple needs sheathed thermocouple very different picture, but their basic structure is substantially the same as the factory sheathed thermocouple, usually from the main part of the hot electrode, insulating sleeve protective tube and junction boxes and other components, usually display instruments, recording instruments and supporting the use of electronic regulator. 1.5 Insulation resistance (insulation resistance) to heat the thermocouple having a pair of electrodes, the thermal resistance of the electrode finger and the protection tube between values; For thermocouple having a plurality of pairs of hot electrodes, also refers to the resistance between the electrodes of each of the heat value . 1.6 thermal response time (thermal response time) when the step change in temperature, change in the output of the thermocouple to the time corresponding to the step change to a predetermined percentage of the desired, generally τ expressed. Sheathed thermocouple production, Henan sheathed thermocouple, measuring force since the instrument class quality provided by the Shanghai Automation Instrumentation Co. measured. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) strong, credible, in Shanghai Zhabei District, flow meters and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the force measured since the instrument into the brilliant and you work for a better future!
