Industry Information
Shockproof electrical contact bimetal thermometer is a kind of field detection instrument for measuring low and medium temperature
2012-2-27 8:41:44

是一种测量中低温度的现场检测仪表。 WSSXN series anti- vibration electric contact bimetal thermometer is a kind of field testing instrument for measuring low and medium temperature. It can directly measure the harsh and vibrating temperature of liquid, steam and gas medium in the range of -80 ℃ ~ + 500 ℃ during various production processes. The shock-resistant electric contact bimetal thermometer is filled with shock-resistant oil from the inside of the instrument, which can effectively overcome the pointer shake caused by mechanical vibration. It is waterproof, corrosion-resistant, shock-resistant, intuitive, easy to read, mercury-free, sturdy Durable and other features, shock-resistant electrical contact bimetal thermometers are widely used in petroleum, chemical, machinery, shipbuilding, power generation, textile, printing and dyeing industries and scientific research departments.

Main features: On-site temperature display, intuitive and convenient; safe, reliable and long service life;
A variety of structural forms can meet different requirements. Mercury-free, easy to read, rugged and shock-resistant.
The protective tube is 1Gr18Ni9Ti stainless steel and titanium molybdenum, which has strong pressure and corrosion resistance.
Pull-type thermometer can be maintained or replaced for a short time without stopping the machine.
The integrated types include axial type, radial type, 135º type and universal type, which are suitable for various site installation needs.
working principle
是基于绕制成环性弯曲状的双金属片组成。 The shock-resistant electric contact bimetal thermometer is based on a bimetal sheet that is wound into a loop shape. When one end is heated and expanded, the pointer is driven to rotate, and the working instrument displays the corresponding temperature value, and prevents environmental vibration. The bimetal thermometer is filled with silicone oil or the display part of the bimetal thermometer is separated from the measurement part to achieve the effect of shock resistance. The shock-resistant bimetal thermometer is divided into two types of integrated shock-resistant electric contact bimetal thermometer and separate shock-resistant electric contact bimetal thermometer.
