The bimetallic thermometer can fine tune?

Bimetallic thermometer according to the using environment is different, can be divided into household bimetallic thermometers and industrial bimetallic thermometer. They work is working principle is to use different expansion coefficient of two kinds of metals ( Or alloy) Piece together form a thermal components, generally made spiral wound, its end ( The free end) Equipped with a pointer. When the temperature changes, the thermal component of curvature change, free end rotation, drive the pointer indicates the temperature value on the dial. The bimetallic thermometer can fine tune? From the point of view of principle, bimetallic thermometer can be fine-tuning. But in actual operation depends. Such as the ordinary household bimetallic thermometer, generally do not need to fine tune, because it USES the environment of a single, accuracy is not high also, With industrial bimetallic thermometer is not the same, some equipment in strong motion state for a long time, we are asking for devices of the bimetallic thermometer calibration, regularly to ensure the accuracy of temperature measurement. When we found that the temperature measurement is allowed to, you can use a word screw gently touch the screw behind the bimetallic thermometer pan, fine-tuning. Major premise is, of course, the bimetallic thermometer belongs to adjustable style, so when buying must show is adjustable.
