What is the use thermometer to protect casing

Thermometer protecting casing is set outside temperature measuring element, can also be pre-installed in the inconvenience of disassembly device with pressure, resist the measurement medium pressure and corrosion effect, make the thermocouple, heat resistance, bimetallic thermometer instrument can work normally. In order to use the different way, a thermometer to protect of the commonly used material is copper and stainless steel casing. Thermometer casing protection is very big, it can protect the thermometer, with explosive, anti-corrosion, high temperature, high pressure, easy to burn the measurement of risk factors, such as medium, the thermometer can not directly contact, then protect the casing are evident. Use a thermometer to protect casing is to protect the inside of the temperature measuring element, is convenient to repair. It can effectively protect the bimetallic thermometer work effectively. Thermometer to protect casing's biggest advantage is easy of bimetallic thermometer replacement, don't need to stop the machine to replace, the safety of installation workers can have very good protection effect.
