Universal bimetallic thermometer

Universal bimetallic thermometerIt works by utilizing the principle that two different metals expand differently when the temperature changes. The main component of industrial bimetallic thermometers is a multi-layer metal sheet composed of two or more metal sheets stacked together. To improve temperature sensitivity, metal sheets are usually made into a spiral coil shape. When the temperature of multi-layer metal sheets changes, the expansion or contraction of each layer of metal is uneven, causing the spiral coil to roll up or loosen. Due to one end of the spiral coil being fixed and the other end being connected to a freely rotatable pointer, when the bimetallic strip senses a temperature change, the pointer can indicate the temperature on a circular scale. The temperature measurement range of this instrument is 200~650 ℃, and the allowable error is about 1% of the scale range. This thermometer has a similar purpose as a rod-shaped glass liquid thermometer, but can be used under conditions that require higher mechanical strength.

Universal bimetallic thermometerIt is a field detection instrument suitable for measuring medium and low temperatures, which can be used to directly measure the temperature of liquefied and gas. Comparison between bimetallic thermometers and similar domestic products: The instrument accuracy level reaches 1.0 level, and the upper shell of the instrument is made of anti-corrosion materials. Its temperature resistance can reach up to 200 ℃ and as low as -40 ℃. The flange structure and double-layer sealing rubber ring have good anti-corrosion and waterproof performance. The welding of the protective tube adopts fully automatic argon gas protective tube, with a firm weld and minimal intergranular corrosion. The scale plate is an aluminum oxide printing plate with a clear and aesthetically pleasing surface. The pointer is internally adjustable. Bimetallic thermometers are available in axial, radial, universal, and other types The length of the probe of the bimetallic thermometer can be customized according to customer needs. On site temperature display, intuitive, convenient, safe and reliable, with a long service life; The core pulling thermometer can be maintained or replaced for a short period of time without stopping the machine. Axial type, radial type, 135 °; There are a complete range of types such as universal type and universal type, which are suitable for various on-site installation needs.
