It is a field detection instrument used for measuring medium and low temperatures, which works by utilizing the thermal expansion characteristics of bimetallic sheets, and its pointer plate is vertically connected to the protective tube. Here is a specific introduction:
Working principle: The main component of a bimetallic thermometer is a multi-layer metal sheet composed of two or more metal sheets stacked together. The two different metals expand differently when the temperature changes. The bimetallic strip is wound into a spiral tube shape, with one end fixed and the other free end connected to the pointer. As the temperature changes, the free end of the bimetallic strip rotates and drives the pointer to rotate to indicate the corresponding temperature value.
Structural features: The dial of the axial bimetallic thermometer is connected to a vertical protective tube, which makes it suitable for installation on a riser and facilitates real-time temperature observation by personnel.
Technical parameters: Its measurement range is usually between -80 ℃ and+500 ℃, with an accuracy level of 1.0, 1.5, etc. The dial diameter comes in various specifications such as 60mm, 100mm, 150mm, etc. The protective tube material is often 304 stainless steel, 316 stainless steel, etc.
Application scenarios: It can directly measure the temperature of liquid, steam, and gas media in various production processes, and is widely used in industrial fields such as chemical, petroleum, power, metallurgy, etc.
