WSS series bimetal thermometer is a temperature-measuring instrument in which the differential thermal expansion of thin dissimilar metals, bonded together into a narrow strip and coiled into the shape of a helix or spiral, is used to actuate a pointer and to show the temperature value. It is also known as differential thermometer. Facilitated with all stainless steel material, it is suitable for corrosive media and environments in chemical process, petroleum and other industry field.
WSS series bimetal thermometer includes three types as per installation: Bottom Mounted, Back Mounted, Arbitrary Mounted.
