Radial bimetallic thermometer

1、 Product Overview

The radial bimetallic thermometer combines two metals with different coefficients of linear expansion, with one end fixed. When the temperature changes, the thermal expansion of the two metals is different, which drives the pointer to deflect to indicate the temperature. This is the radial bimetallic thermometer, with a temperature measurement range of -80~600C. It is suitable for temperature measurement in industries with low precision requirements. Bimetallic sheets, as a temperature sensing element, can also be used for automatic temperature control.

2、 Main features

On site temperature display, intuitive and convenient; Safe and reliable, with a long service life; Multiple structural forms can meet different requirements.

3、 Working principle

Radial bimetallic thermometers are composed of bimetallic sheets wound in a circular curved shape. When one end expands due to heat, it drives the pointer to rotate, and the working instrument displays the corresponding temperature value.
