WSSXN series of seismic electric contact bimetal thermometer is a measure of low-temperature field instrumentation. Poor -80 ℃ ~ +500 ° C range in a variety of production processes within the liquid, vapor and gases, and environmental sites and vibration temperature can be measured directly. Electrical contacts, bimetal thermometer of the seismic charge and seismic oil from the inside of the instrument, which can effectively overcome the mechanical vibration pointer jitter on the design principle and structure of a waterproof, corrosion resistant, shock-resistant, intuitive, easy reading, no mercury damage, sturdy durability and other characteristics, seismic electric contact bimetal thermometer is widely used in petroleum, chemical, machinery, shipbuilding, power generation, textile, printing and dyeing and other industrial and scientific research departments. 

 The main features 
 The scene shows the temperature, easy and intuitive; safe, reliable, long life; 
 Variety of structural forms, which can meet different requirements. No harmful mercury, easy to read, sturdy seismic. 
 Protection pipe for 1Gr18Ni9Ti stainless steel and molybdenum, titanium, pressure, corrosion resistance. 
 Drawing Core thermometer without stopping the machine short-term maintenance or replacement of the movement. 
 One-axial type, the full range of radial type, 135 o type, universal type, to meet the needs of the various field installation. 
 Working principle 
 Seismic electric contact bimetal thermometer is based around made of ring curved bimetal. The end of the thermal expansion, driven pointer rotation, work meter will show the temperature value, and should prevent the effect of environmental vibration in the bi-metal thermometer internal filling silicone oil or bi-metal thermometer part and measurement part of the separation in order to achieve seismic. Seismic bimetallic thermometer is divided bimetallic thermometer two kinds of integrated seismic electric contact bimetal thermometers and discrete seismic electrical contacts.
