Bimetallic thermometer insertion depth and heat tube length is the same?

As a professional manufacturer thermometer, sometimes after receiving customized bimetallic temperature time, will get not clear of the bimetallic thermometer inserted depth and heat tube length. Many people will think this is a meaning, both we can talk about the bimetallic thermometer inserted depth and the relationship between the heat pipe. Generally speaking, the insert depth of the bimetallic thermometer from thermal pipe end, at least 40 mm, special temperature range ( 0 - 50C） You will need to 50 mm, that is, more than 50 mm length is ok. In addition, also want to consider the installation of bimetallic thermometer, said pipe using bimetallic thermometer, for example, if the connection pipe installed on the base or flange, etc. , to count the length of these parts are. So we will say in the description of the bimetallic thermometer inserted depth teeth ( Install the teeth or accessories) Or don't even teeth. If insert depth of tooth XXmm, insert depth = the length of the heat pipe + the length of the teeth; If the insertion depth is not even the teeth, insert depth = the length of the heat pipe. Bimetallic thermometer working principle is to 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. It can be directly measured various - in the process of production 50℃- + 500 ℃ within the scope of liquid, steam and gas medium temperature. Also very convenient to use, as long as the heat tubes inserted into the tested medium.
