Bimetallic thermometer temperature sensing element can repair?

Bimetallic thermometer is often used to install in pipelines, ships, factories and machinery; Those metal thermometer temperature sensing element can repair? Instrument replied, bimetallic thermometer temperature sensing element is bimetallic strip, two pieces of bimetallic strip is lap welded together, if bending failure can't be repair. If the thermal bimetal thermometer component is damaged, will cause the temperature measurement is not accurate, recommend replacing new bimetallic thermometer. Bimetallic thermometer is a 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.
