A bimetallic thermometer is an on-site detection instrument used to measure low to medium temperatures. Bimetallic thermometers can directly measure the temperature of liquid, vapor, and gas media within the range of -80 ℃ to+500 ℃ in various production processes.

Bimetallic thermometers are used in the chemical and petrochemical industries; Power engineering; Food sector; Mechanical manufacturing and general factory construction.

The advantage of bimetallic thermometers is that they display temperature on site, which is intuitive and convenient; Safe and reliable, with a long service life and fast readings, it has received unanimous praise from a wide range of users. Today we will learn about the difference between radial and axial bimetallic thermometers:

Axial bimetallic thermometer: The pointer plate is vertically connected to the protective tube.

Radial bimetallic thermometer: The pointer plate is connected parallel to the protective tube.

In order to meet the needs of actual production and meet the characteristics of different equipment, you can choose axial or radial bimetallic thermometers according to your needs. Their temperature sensing tube length and screw thread can be customized according to customers;

It should be noted that during the storage, installation, use, and transportation of bimetallic thermometers, collision with the protective tube should be avoided as much as possible, and the protective tube should not be bent or deformed. During installation, it is strictly prohibited to twist the instrument housing.

The principle and structure of radial and axial bimetallic thermometers are the same. They use a threaded bimetallic strip as a temperature sensing device and install it inside a protective sleeve. One end is fixed, called the fixed end, and the other end is connected to a thin shaft, called the free end. A pointer is installed on the free end axis. When the temperature changes, the free end of the temperature sensing device rotates accordingly, driving the pointer on the thin shaft to produce an angle change, indicating the corresponding temperature on the dial.
