Bimetallic thermometer 1 precision. 0 s and 1 s. 5 which good?

Bimetallic thermometer with high cost performance got the favour of all walks of life. But, due to the different industry is different to the requirement of the precision of the bimetallic thermometer. So, bimetallic thermometer 1 precision. 0 s and 1 s. 5 which good? The answer is good. Why do you say that? We all know that the principle of the 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. Thus the heat element will affect the precision of the bimetallic thermometer. 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. 0 is ok, only used in industrial equipment of precision of the bimetallic thermometer sometimes only request 1. 0.
