Water Themometer A temperature meter is an instrument that uses different principles to measure the temperature or temperature gradient of an object (or space). Common is a pointer bimetalal thermometer with a dial that directly measures gas, liquid, and steam. Widely used in machinery, shipbuilding, petrochemical, metallurgy, electric power, light industry and research sectors. Operating principle of the temperature meter With spiral temperature element made of hot double metal to measure temperature, temperature element in the protective tube, one end is fixed end, the other end is a free end, free end connected to a fine axis, shaft end equipped with pointer, when the temperature changes, temperature element temperature, the free end around the fixed end, and drive the pointer rotation, thus displayed on the dial.
