All stainless steel bimetallic thermometer threaded connections

All stainless steel bimetallic thermometer is a round shape into threaded heat bimetallic strip as thermal devices, and put it in the stainless steel protective tube, one end is fixed, known as the fixed end, the other end connection on a thin shaft, a 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.
