Angstrom Bimetallic Thermometers: How They Work and Complete Specifications

Bimetallic thermometers are mechanical temperature measurement instruments that use a coiled strip made of two different metals with varying coefficients of thermal expansion to convert temperature changes into mechanical movement, rotating a pointer across a calibrated dial to indicate temperature from -20°C to 650°C without requiring external power. Angstrom bimetallic thermometers feature high-grade stainless steel construction, available in dial sizes of 63mm (2.5"), 100mm (4"), and 160mm (6"), stem lengths from 63mm to 300mm (2.5" to 12"), and mounting options including lower mount, center back mount, and adjustable angle for UAE industrial applications across Dubai, Abu Dhabi, and the Emirates including HVAC systems, food processing, chemical plants, and process control.

What is a bimetallic thermometer and how does it work?

A bimetallic thermometer is a mechanical temperature measurement instrument based on the differential thermal expansion of two different metals bonded together. The sensing element consists of a coiled strip made of two metals with different coefficients of thermal expansion. When temperature changes occur, the metal with higher expansion coefficient expands more than the other during heating, causing the strip to bend or coil. During cooling, the strip moves in the opposite direction as the metals contract at different rates. This mechanical movement is directly linked to a pointer that rotates across a calibrated dial, providing an instant visual indication of temperature. The beauty of this design is its simplicity and reliability—no external power required, no electronics to fail, and instant response to temperature changes. In UAE's industrial facilities across Dubai, Abu Dhabi, and the Emirates, bimetallic thermometers provide robust, maintenance-free temperature monitoring in HVAC systems, process equipment, food processing, and any application requiring reliable temperature measurement from -20°C to 650°C.
