Tips: Thermowell of thermocouple
To extend service life of thermocouple and protect it from chemical and mechanical damages, thermode (including insulating bush) is generally enclosed within thermowell so as to protect, fasten and support thermode. Materials which are used for thermowell should have favorable gas tightness to prevent external medium from permeating into the thermowell. With enough mechanical strength, it can resist bending and pressure; it has physical and chemical properties are stable, thus it will not corrode thermode. Moreover, in environment of high temperature, it has favorable property of high temperature resistance and anti-seismic property. And selection of thermowell generally depends on temperature measurement range, length of the heating zone, environmental atmosphere and lagging requirements of temperature measurement.
