The higher the precision of the bimetallic thermometer is better?

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. Using the environment is different, also different to the requirement of the precision of the bimetallic thermometer. So the higher the precision of the bimetallic thermometer is better? The answer is, not necessarily. In order to our common one. Level 5 and 1. To see a level 0. That we are each table 1 requires precision. 0? The answer is no, because in normal use, the precision of the bimetallic thermometer of general family expenses to 2. Level 0, only used in industrial equipment on the precision of the bimetallic thermometer sometimes only request 1. Level 0.
