Radial and universal bimetallic thermometer

Bimetallic thermometer 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. Common bimetallic thermometer are radial bimetallic thermometer, axial bimetallic thermometer and universal type of bimetallic thermometer. As shown, the radial and universal bimetallic thermometer is the biggest difference is not the same as the header and thermal connection direction. Universal type bimetallic thermometer is compatible with the radial bimetallic temperature and axial bimetallic thermometer features. So the price also will be slightly more expensive. As to what should choose which one, still need to use the environment and comprehensive consideration of cost performance.
