Measuring the temperature of the liquid pipe with what?

Instrument to tell everyone: measuring the temperature of the liquid pipe recommend using bimetallic thermometer. Because of the bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. So this kind of thermometer thermometer is also called pipes. Because of different pipe length and diameter? So the bimetallic thermometer heat pipe diameter and length can be customized by the client. Commonly used pipe the heat pipe diameter of the thermometer:? 6毫米,6。 35mm，8mm,9mm,10mm,12mm。 The length of the 50 - 2000 mm is optional, you can choose according to the requirements to the corresponding pipe size thermometer. Structure bimetallic thermometer is the round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, called the free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial.
