Do you know the type of the bimetallic thermometer meaning

Bimetallic thermometer to two different linear expansion coefficient of metal together, one end fixed, when the temperature changes, the two different kinds of metal thermal expansion, drive the pointer to indicate the temperature, that is the bimetallic thermometer. Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. So do you know the type of the bimetallic thermometer meaning? The following instruments to tell you. In order to meet the needs of practical production, model selection have installation way, structure, classification of dial diameter etc. Bimetallic thermometer fixed installation forms: movable external thread pipe joint, movable threaded pipe joints, fixed nipple, card sets of nipple, flange joint and a fixed flange. Bimetallic thermometer pointer plate with the direction of protecting tube connection bimetallic thermometer can be divided into axial, radial and 135 & deg; To type and universal type four. (1) the axial type bimetallic thermometer: pointer vertical connection tube plate and protection. (2) the radial type bimetallic thermometer: pointer GuanPing line connection plate and protection. ③135度; The bimetallic thermometer: pointer tube plate and protection into 135 & deg; The connection. (4) universal type bimetallic thermometer: pointer plate connected to the protecting tube Angle can be arbitrary adjustment. Bimetallic thermometer dial nominal diameter: 150 bimetallic thermometer is around 60, 100 a formation of thermal bimetal screw 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.
