The WSS series bimetallic thermometer is a field detection instrument for measuring medium to low temperatures. Bimetal thermometers can directly measure the temperature of liquid, steam, and gas media within the range of -80 ° C to+500C in various production processes
The bimetallic thermometer is a thermal Bimetal wound into a spiral thread as a temperature sensing device and installed in 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. Install a pointer on the free end axis. When the temperature changes, the free end of the temperature sensing device rotates accordingly, driving the pointer on the fine shaft to produce an angle change. The corresponding temperature can be indicated on the dial according to the connection direction between the bimetallic thermometer dial and the protective tube. The bimetallic thermometer can be divided into four types: axial type, radial type, 135 ° directional type, and universal type
Bimetallic thermometer
1. Axial bimetallic thermometer: the pointer plate is vertically connected to the protective tube
2. Radial bimetallic thermometer: parallel connection between pointer plate and protective tube
3. 135 ° directional bimetallic thermometer: the pointer plate is connected to the protective tube at 135 °
4. Universal bimetallic thermometer: The connection angle between the pointer and the protective tube can be adjusted arbitrarily. Bimetal thermometers have different installation and fixation forms: movable external threaded pipe joints, movable internal threaded pipe joints, fixed threaded joints, sleeve threaded joints, sleeve flange joints, and fixed flanges.
