What role does the bimetallic thermometer sheath?

Bimetallic thermometer, now is the indispensable industrial production field indicating temperature measuring instrument, applicable occasions can vary, so the protection of the bimetallic thermometer tube ( Sheath) Is essential. The bimetallic thermometer protecting tube ( Sheath) What is the role? The so-called protection tube ( Sheath) , just as its name implies is to protect the thermometer. With explosive, corrosive, high temperature and high pressure, easy to burn the measurement of risk factors, such as medium, the thermometer can not directly contact, then the effect of protecting tube are evident. In order to protect the inside of the temperature measuring element, is convenient to repair. If the material is corrosive, high temperature, high pressure, easy explosion risk factors such as, easy to burn, you must add protection casing. Also is the first in a pipe or container welding screw type or flange installation casing pipe installation, install the bimetallic thermometer in again. If the measurement is the conventional material such as air, inert gas or water, there is no need to protect casing, directly installed on the joint line, you can also save money. Through the above simple narrative, we understand that protecting tube ( Sheath) For the role of the bimetallic thermometer is very big, can protect the inside of the temperature measuring element, if the bimetallic thermometer is broken, is very convenient for maintenance.
