WSSN series of seismic bimetal thermometer is a low-temperature field measurement instrumentation. It can directly measure a variety of production processes -80 ℃ ~ +500 ℃ within the liquid, vapor, gas and environmental sites, and vibration of harsh temperatures. The bimetallic thermometer seismic design principles and structure from a waterproof, corrosion, shock-resistant, intuitive, easy to read, victims of mercury-free, durable, etc., bimetal thermometers are widely used in seismic oil, chemicals, machinery, shipbuilding, power generation , textile, printing and dyeing industries and research sectors. 

 Key Features 
 Site show that the temperature, easy and intuitive; safe, reliable, long life; 
 Variety of structural forms, which can meet different requirements. Mercury harm, easy to read, strong seismic. 
 Stainless steel protection tubes for the 1Gr18Ni9Ti two titanium and molybdenum, pressure, anti-corrosion ability. 
 Pulling thermometer short-term maintenance or replacement without stopping the movement. 
 Integrated with axial, radial type, 135o-type, universal type and other variety, adapted to a variety of on-site installation. 
 Work 
 Seismic bimetallic thermometer is made based around the ring of curved-shaped bimetal composition. When one end of thermal expansion, driven pointer rotation, working instrument will show the temperature value to be, and the prevention of environmental vibration in the internal filling silicone bimetal thermometer bimetal thermometer or some part of the separation and measurement to achieve the seismic effect.
