Bi-Metal Thermometer, Refrigeration Gauge, Temperature Gauges, Process Control Instruments, Mercury In Steel Type Thermometer

Temperature reflects the momentous thermal condition of a homogenous material. Measurement of temperature normally requires close, direct contact between the material and the sensor in such a manner that the sensor responds quickly to the temperature of the material.

Bi-Metal Thermometer


The bi-metallic element consists of two strips of different metals, with different thermal expansion coefficients, inseparably joined together. This strip is spirally or helically wound with one end fixed to the body of the thermometer, and the other attached to the axis of a pointer. Measurement of temperature is made with the bi-metallic system inside the temperature sensor. Temperature variation influences the bi-metallic strip such as to rotate the pointer; this rotation is indicated on a dial.
