Description
Product introduction
WSS series bimetallic thermometer is a kind of on-site measuring instrument for low and medium temperature. Bimetal thermometer can directly measure the temperature of liquid, steam and gas medium in the range of - 80 ℃ to + 500 ℃ in various production processes.
Main features
Display temperature on site, intuitive and convenient; It is safe and reliable with long service life;
Various structural forms can meet different requirements.
working principle
Bimetallic thermometers are based on bimetallic sheets that are wound in a circular bending shape. When one end is heated and expanded, it drives the pointer to rotate, and the working instrument will display the corresponding temperature value.
