Why do you want to know the precision of the bimetallic thermometer?

Bimetallic thermometer specification is various, a variety of shapes, industrial equipment, also has a home. Usually require high precision industrial equipment, and the precision requirement of household bimetallic thermometer is relatively not that high. But we in the production of bimetal thermometer is precision need to be marked, the reason is: the precision of the bimetallic thermometer is used to calculate the maximum absolute error of a parameter. The permissible error of the maximum absolute error = | | | = | X precision range, for example, the bimetallic thermometer measurement range of 0 ~ 300 ℃ accuracy of 1. Level 5, margin of error for 300 x1. = + / - 5% 4. 5 c 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.
