Gimbal bimetal thermometer

Principle of operation

The gimbal bimetal thermometer is an industrial bimetal thermometer, and the main component is a multi-layer metal sheet composed of two or more metal sheets stacked together. In order to improve the sensitivity of temperature measurement, an instrument that can automatically and continuously record changes is usually made into a spiral coil shape. When the temperature of the multi-layer metal sheet changes, the individual layers of metal expand or contract by different amounts, causing the spiral to roll up or loosen. Because one end of the spiral coil is fixed and the other end is connected to a hand that can rotate freely, the two metals will bend by different amounts of volume when the temperature changes. One end is fixed, and the other end is displaced with the change of temperature, and the displacement is close to linear with the air temperature. The self-recording system consists of a self-recording clock, a self-recording pen, which is connected to a magnifying lever and manipulated by an inductive element, so that when the bimetal feels a temperature change, the pointer indicates the temperature on a circular indexing scale. This thermometer is used similarly to a rod-shaped glass-liquid thermometer, but can be used in conditions where strength is required.

Applications

Universal bimetal thermometer Bimetal thermometer is a field detection instrument suitable for measuring medium and low temperatures, which can be used to directly measure the temperature of liquefaction and gas. Comparison of bimetal thermometer and similar products: the accuracy level of the instrument reaches 1.0, the upper shell of the instrument is made of anti-corrosion materials, and its temperature resistance can be as high as 200 °C, and the lowest is -40 °C. Flange structure, double-layer sealing rubber ring, so anti-corrosion, good waterproof performance. The welding of the protective tube adopts automatic argon protective tube, which has a firm weld and small intergranular corrosion. The scale plate is an aluminum oxide printing plate, with a clear surface and beautiful style. The hands are internally adjustable. Bimetal thermometers are available in axial, radial, and universal head models. Bimetal thermometer probe lengths can be customized according to customer needs. On-site temperature display, intuitive, convenient, safe and reliable, long service life; The core-pulling thermometer allows for short maintenance or replacement of the movement without stopping the machine. Axial type, radial type, 135º type, universal type and other varieties are complete, which are suitable for various on-site installation needs.
