Instrument to tell you the use of bimetallic thermometer cycle is associated with what?

Bimetallic thermometer working principle is to round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, called the free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial. As a professional bimetallic thermometer manufacturers, today we will talk about the use of bimetallic thermometer cycle is associated with what? 1. The material of raw materials, SS304 stainless steel and the use of ordinary material 201 cycle must be different; 2. Using the environment, the normal environment and high corrosion, strong shock vibration under the environment of the use of cycle is certainly different. So, we can say, SS304 stainless steel bimetal thermometer, in normal, Not high corrosion, strong shock) The use environment, use cycle can be up to 10 years. Notice also that the bimetallic thermometer as measuring instruments, calibration is to do each year.
