是一种测量中低温度的现场检测仪表。 Shockproof bimetal thermometer is a kind of on-site detection 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 ℃ in various production processes. The shock-resistant bimetal thermometer has the characteristics of waterproof, corrosion-resistant, shock-resistant, intuitive, easy to read, mercury-free, rugged and so on. , Textile, printing and dyeing industries and scientific research departments.
Main features: 1. On-site display of temperature, intuitive and convenient; safe and reliable, long service life; 2, a variety of structural forms, can meet different requirements. Mercury-free, easy to read, rugged and shock-resistant. 3, the protection pipe is 1Gr18Ni9Ti stainless steel and molybdenum titanium, with strong pressure and corrosion resistance. 4. The core-pulling thermometer can be maintained or replaced for a short time without stopping the machine. 5. There are complete types of axial type, radial type, 135o type, and universal type, which are suitable for various site installation needs.
Working principle of shock-resistant bimetal thermometer:
是基于绕制成环性弯曲状的双金属片组成。 The shock-resistant bimetal thermometer is based on a bimetal sheet wound in 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 can directly measure the harsh and vibrating temperature of liquid, steam and gas medium in the range of -80 ℃ ～ + 500 ℃ in various production processes. The shock-resistant bimetal thermometer is infused with silicone oil through the dial to dampen the vibration of the hands and internal components, so it effectively eliminates the effects of medium pulsation and environmental vibration, making the indicator stable and reliable, and also increasing the service life of the instrument .
