The factors influencing insertion depth of the bimetallic thermometer have?

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. Bimetallic thermometer is mainly the temperature of the measurement of low temperature field, so widely used in all kinds of industrial equipment. Today let's say what are the factors influencing the bimetallic thermometer inserted depth of? Influence WSS series bimetallic temperature insertion depth factors there are two. The first is the range of measuring temperature, because the measuring temperature range determines the double the length of the metal sensors ( Double metal sensors installed in the bottom of the heat pipe) 。 In general, from heat tube end, at least 40 mm, that is the length of more than 40 mm is ok. The second has to do with WSS series bimetallic thermometer installation, for example, the said pipe with WSS series bimetallic thermometer, or if the connection pipes installed base flange, etc. , to count the length of these parts are.
