Bimetallic thermometer

WSS series bimetal thermometer is an on-site detection instrument for measuring low and medium temperature. The bimetal thermometer can directly measure the temperature of liquid, steam and gaseous media in the range of -80℃~+500℃ in various production processes.

Principle structure

The bimetallic thermometer uses a hot bimetallic piece wound into a thread as a temperature sensing device, and it is installed in a protective sleeve. One end is fixed, called the fixed end, and the other end is connected to a thin shaft, called Free end. There is a pointer on the free end spool. 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.

Selection instructions

According to the connection direction of the bimetal thermometer dial and the protective tube, the bimetal thermometer can be divided into four types: axial type, radial type.
①Axial bimetal thermometer: The pointer plate is connected vertically to the protection tube.
②Radial type bimetal thermometer: The pointer disc is connected in parallel with the protection tube.
