Do you know about bimetal thermometer?

Bimetallic thermometer temperature sensing element is two pieces of expansion system made of different metal stitch welding together. Bimetallic strip after heat due to the expansion of the two sheet metal bending length is not the same. The length and width of the linear expansion of the higher the temperature the greater the difference, thus draws the greater the bending Angle, the bimetallic strip are made into spiral tube, this is the working principle of bimetallic thermometer. Bimetallic thermometer is a kind of measuring instrument in the field of low temperature detection, temperature measuring range is commonly - 80~600℃。 Easy to use, strong and durable. On many occasions to replace industrial glass liquid thermometer. Can be widely used in petrochemical, electric power, medicine, building materials, metallurgy industry, etc. The bimetallic thermometer connection location of the indicating device and testing components can be divided into: radial type ( Straight type) , axial type ( Angle) , universal type ( Adjustable Angle) 。 Bimetallic thermometer can be used in any high temperature occasion need it, it adopts the SS304 stainless steel shell can not only make it adapt to the high temperature environment, but also for liquid, gas, such as erosion, water environment is easy to damage has a strong protective effect, its wear resistance, corrosion resistance performance, suitable for all kinds of harsh harsh environment, and can ensure the accuracy of temperature measurement, the precision for & plusmn; 1. 5%, for industrial measurement is a very accurate numerical, and has strong thermal response function, thermal response time usually need only 40 seconds, compared to other heat test instrument, is very fast and useful. So, in industrial production and manufacturing, bimetallic thermometer is the most widely used, because it can resistance to high temperature of 600 c, general won't reach the temperature of the thermometer. So the bimetallic thermometer thermometer became the first choice from all walks of life.
