Bimetallic thermometer can fine-tune alignment?

Bimetallic thermometer is a professional measurement of low temperature field temperature thermometer. According to the installation environment using environment is different, the bimetallic thermometer can be refined classification. The operation principle of the bimetallic thermometer 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. Bimetallic thermometer, buyer knows that, in the rule parameters have a is & other; Whether you need the adjustable screw & throughout; And the function of the adjustable screw is when bimetal temperature measurement error, we can through the adjustable screw to adjust, so can a certain alignment? The problem depends on the specific circumstances, if it is a professional personnel with professional testing equipment, we can certainly put it alignment. But if we are not professional under the condition of constant temperature measuring equipment, adjust themselves, are typically hard to alignment.
