Bimetallic thermometer which a few kinds are there?

Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. 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. Those metal thermometer which a few kinds are there? Follow the below small make up together to get to know. A, bimetallic thermometer in the direction of the connection pointer plate and protecting tube can be divided into the following categories: type 1, axial bimetallic thermometer, pointer plate and vertical connection protection tube; Type 2, radial bimetallic thermometer, pointer and protect GuanPing line connection; 3, universal type bimetal thermometer, pointer plate and protecting tube can be arbitrary Angle adjustment. Second, bimetallic thermometer, thermal components form a planar spiral and a straight spiral two kinds big. Three, bimetallic thermometer installation forms: movable external thread pipe joint, movable threaded pipe joints, fixed nipple, card sets of nipple, flange joint and a fixed flange.
