Bimetal Thermometers

Professional Bimetal Thermometer Solutions

A bimetal thermometer is a mechanical temperature measuring instrument that operates without external power, making it ideal for industrial applications where reliability and accuracy are paramount. As a leading bimetal thermometer supplier in UAE, we provide precision instruments that utilize the thermal expansion properties of two different metals to deliver accurate temperature readings.

Bimetal Thermometer Working Principle

The bimetal thermometer working principle is based on the differential thermal expansion of two bonded metal strips. When temperature changes occur:

  • Two metals with different expansion coefficients are bonded together
  • Temperature changes cause unequal expansion between the metals
  • This creates a bending motion proportional to temperature change
  • The mechanical movement rotates a pointer across a calibrated dial
  • No external power source is required for operation

Technical Construction and Design

Understanding the bimetal thermometer diagram reveals the sophisticated engineering behind these instruments:

  • Bimetallic Element: Precision-manufactured coiled strip of two bonded metals
  • Mechanical Linkage: Converts thermal expansion into rotational movement
  • Pointer Assembly: Indicates temperature on calibrated dial face
  • Case Construction: Protective housing with viewing window
  • Connection Options: Various mounting and process connections available
