Bimetallic thermometer is oil filled filling of oil

Bimetallic thermometer header contains oil called oil-extended bimetallic thermometer, also called seismic bimetallic thermometer. Seismic bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of the liquid, steam and gas medium and bad temperature and vibration environment places. The thermometer from the design principle and the structure has the waterproof, corrosion resistance, vibration resistance, intuitive, easy reading, no mercury pollution, durable and other characteristics, widely used in petroleum, chemical industry, machinery, ships, electricity, textile, printing and dyeing and other industrial and scientific research departments. Bimetallic thermometer is oil filled filling of oil? Bimetallic thermometer is pouring silicone oil and glycerin, aseismatic function are the same, but the silicone oil than glycerol good low temperature resistance, if use environment - 20 ℃, glycerin crystallization, silicone oil or keep normal work. Principle of seismic bimetallic thermometer is made around the circular bent based of bimetallic strip. Side heated expands, turns the pointer, the instrument will show should value, and prevent environmental vibration within the bimetallic thermometer filling or silicone oil of bimetallic thermometer display section and some separation measure to achieve seismic effect.
