Stainless Steel Bimetal Thermometer

Short Description:

Product Detail

Product Tags


Bimetal thermometer is used for measuring medium and low temperature field detector. A meter can be used to directly measure the temperature of gases and liquids. Compared with the glass mercury thermometer, it has the advantages of non-toxic, easy to read, firm and durable.

Structure Principle

Bimetal thermometers for temperature measurement are through the system internally, by the double metal material made of spiral spring type bimetal sheet to achieve temperature sensing. Its bimetal material is composed of two indivisible metal sheet, because the thermal expansion coefficient of the two metal sheet is different, so it will have different degrees of extension deformation under the temperature change. This extension deformation is proportional to the temperature. One end of the metal sheet is fixed and the other end is fixed with the indicating shaft, so as to drive the indicating shaft to rotate and indicate the corresponding temperature value on the dial when the metal sheet is extended and deformed.

■Bimetal thermometer when measuring temperature sensing tube is immersed in the measured medium must be longer than the length of the sensing element, generally greater than or equal immersion length 75mm,0-50 degree range immersion length must be greater than120mm,to ensure the accuracy of measurement.
■|f the measuring medium is affected by pressure, it is necessary to select connector thread for sealing form.
■When measuring corrosive media, please pay attention to the material selection requirements.
■For other requirements, it must be confirmed by company technical department.
