Understanding Bimetallic Thermometers: Precision Temperature Measurement
Bimetallic thermometers are essential instruments for accurate temperature measurement across industrial, commercial, and laboratory applications. At Angstrom, we manufacture high-quality bimetallic thermometers that combine precision engineering with robust construction for reliable performance in demanding environments.
How Bimetallic Thermometers Work
The operating principle of bimetallic thermometers is based on the differential thermal expansion of two different metals bonded together. Here's how the technology works:
The Bimetallic Strip Mechanism
A bimetallic thermometer contains a coiled strip made of two different metals with varying coefficients of thermal expansion. When temperature changes occur:
- Heating: The metal with higher expansion coefficient expands more than the other, causing the strip to bend or coil
- Cooling: The strip moves in the opposite direction as the metals contract at different rates
- Mechanical Translation: This movement is mechanically linked to a pointer that indicates temperature on a calibrated dial
Key Components
The thermometer consists of several critical components working together:
- Bimetallic Element: The sensing element that responds to temperature changes
- Stem: Houses the bimetallic element and provides insertion into the measured medium
- Case: Protects the dial and mechanism
- Dial: Displays temperature readings with clear markings
- Pointer: Indicates the current temperature reading
