Bimetallic thermometer precision represent?

Bimetallic thermometer is used widely in our life, different areas are not the same as to the accuracy requirement, then you know what the precision of the bimetallic thermometer stand for? Under normal circumstances, the precision of bimetallic thermometer is & other; The accuracy of the bimetallic thermometer measurements & throughout; , is a thermometer in value is consistent with the measured temperature variables of true value. In industrial measurement, the accuracy of the often said with a precision instrument, precision is the maximum error of the reference to remove & other; ± ” Number and & other; %” Number. Precision measuring instrument is one of the important indicators of quality, our country industrial instruments into 0. 1, 0. 2, 0. 5, 1. 0, 1. 5, 2. 5, 5. 0 seven grades, and logo on the meter scale or nameplate. Accuracy level customarily called precision level. Bimetallic thermometer, for example. Precision grade is it permissible error of the dial scale value by it's percentage, its accuracy level the greater the number of permissible error of dial scale limit value is larger. Range, the greater the same precision level, it measured the absolute value of the temperature the greater the margin of error. We produce the precision of the part of the bimetallic thermometer is divided into 1. 5 and 1. Two kinds of 0. 1. Level 5 and 1. Level 0 respectively under normal use, the the permissible error of the thermometer was range & plusmn; 1. 5 and & plusmn; 1. 0%
