The bimetallic thermometer with a magnet

Bimetallic thermometer with magnet is our commonly used surface thermometer at ordinary times, also called magnet thermometer. Surface thermometer is to rely on the principle of the double metal heat bilges cold shrink principle of sensors to work, by contact spring or magnet at the bottom of the thermometer to measure the metal surface and reading. This type of double metal surface thermometer can range from - 40 c to 500 c, the precision can be in for some using occasions for accuracy is not high, can yet be regarded as a money and cheap thermometer of beauty. Surface thermometer magnets have double magnet thermometer, single magnet thermometer, spring has the single spring thermometer, you can choose according to the requirements. Surface thermometer used in pipelines, chemical equipment, used to measure the surface temperature, special thermometer is pipes. Surface thermometer use note: cannot adsorption on the stainless steel material, must pay attention to surface temperature sensor is installed, it will determine the surface temperature measurement of accurate or not. Spring loaded surface thermometer again to pay attention to when using the length of the spring and the diameter to be fixed. In addition, when using, pay attention to clean up and check, regularly test the measured values.
