100mm Dial -20~120 °C All Stainless Steel Adjustable Angle Bimetal Thermometer
Description
The bimetal thermometer measures by thermal expansion. A bimetal thermometer uses a bi metal spring as temperature sensing element. This technology uses a coil spring made of two different types of metals that are welded or fastened together. These metals could include copper, steel, or brass. One must have low heat sensitivity while the other metal has high heat sensitivity. Whenever the welded strip is heated, the two metals change length based on their individual rates of thermal expansion. Since the two metals expand to different lengths, the bimetallic strip is forced to bend or curl towards the side with a lower coefficient of thermal expansion. The movement of the strip is used to deflect a pointer over a calibrated scale which then indicates temperature to the user. Their construction is simple, yet rugged. They are suitable for most applications and measure a range from -50°C to 600°C. They come with multiple entry combinations and provide high repeatability with an accuracy ± 1% FSD.
