How to choose suitable bimetallic thermometer according to installation environment?

Bimetallic thermometer field widely used, install environment also each are not identical, the requirement for the shape of the bimetallic thermometer is much, so there will be a radial, axial, universal three connection mode. So how to choose suitable bimetallic thermometer according to installation environment? As shown, the radial and axial bimetallic thermometer is the biggest difference is not the same as the header and thermal connection direction. Considering the reading is convenient, choose according to installation environment bimetallic temperature time, make sure the convenient reading after the installation is complete. 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.
