The bimetallic thermometer should be inserted into the measure how deep

Bimetallic thermometer is widely used in industrial equipment, its working principle is to use different expansion coefficient of two kinds of metals ( Or alloy) Piece together form a thermal components, generally made spiral wound, its end ( The free end) Equipped with a pointer. When the temperature changes, the thermal component of curvature change, free end rotation, drive the pointer indicates the temperature value on the dial. According to the needs of the working principle and installation environment, can be made into radial bimetallic thermometer, axial bimetallic thermometer and universal type of bimetallic thermometer. When use is needed to insert the measured medium heat pipe. So exactly how deep insertion are suitable? A general way, the entire heat tubes inserted into all good, that is right, but from the perspective of a thermometer manufacturers of professional, should be two-thirds of the heat pipe can be inserted into the liquid to be tested. Why do you say that? Because the temperature is at the bottom of the internal thermal components, only by immersion temperature sensing element, the measured medium to measure the temperature accurately.
