Purchase of bimetallic thermometer?

Bimetallic thermometer is 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 is a kind of measuring instrument in the field of low temperature detection, it can be directly measured various - in the process of production 80℃- + 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 measured medium, installation can be fixed on the pipeline, so buy bimetallic thermometer need to pay attention to what? In addition to the accessories material, insert depth is also very important. Insertion depth is too long can cause can't install or waste; Insertion depth is too short, cannot accurate measurement. In fact, the 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 50 mm, that is more than 50 mm length 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.
