What Is The Difference Between A Thermocouple And A Bimetal Thermometer?

Oct 16, 2021

The bimetal thermometer is actually very similar to the thermocouple. Because of the difference in temperature measurement, it is more suitable for field detection in medium and low temperatures, measuring the temperature of liquid vapor and gaseous media in the range of -80℃-+500℃ in various production processes.

The high temperature in the industry is the use of thermocouples. Of course, the low temperature is the most suitable bimetal thermometer. The main component of the bimetal thermometer is a multilayer metal sheet composed of two or more metal sheets laminated together, using two different types The principle that metals expand differently when the temperature changes. It is based on a bimetallic sheet wound into a circular curved shape. When one end is heated and expanded, it drives the pointer to rotate, and the working instrument displays the temperature value corresponding to the thermoelectric potential. The main component of an industrial bimetal thermometer is a multilayer metal sheet composed of two or more metal sheets laminated together.

Bimetal thermometers are still widely used in China and similar products are also very large. Bimetal thermometers have axial type, radial type, universal type and other meter head models. The length of the bimetal thermometer probe can be selected according to the customer Need to be customized.

It is widely used in instrument chemical industry, metallurgy, textile, food and other industries. The bimetal thermometer is an on-site detection instrument for measuring low and medium temperatures. It can directly measure the temperature of liquid vapor and gaseous medium in the range of -80℃-+500℃ in various production processes. The on-site temperature display is intuitive, convenient, safe and reliable, and has a long service life; the core-pulling thermometer can be maintained or replaced in a short time without stopping the machine. Axial type, radial type, 135o type, universal type and other varieties are complete, which are suitable for various on-site installation needs.
