Thermowells are important components in all temperature measurement applications. They can be installed and used with thermocouples, thermal resistors, bimetal thermometers, etc. Thermowells can separate corrosive, high-temperature, high-pressure, and large-flow media from temperature sensors. At the same time, users can also replace sensors during work.
The Thermowells we supply at Sino-Inst are available in a variety of styles and materials to meet various application requirements. Usually, casing is mainly divided into welded type, threaded type and flange type.
