Bimetallic thermometer radial and axial mean?

Everyone knows 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. Those metal thermometer of radial and axial mean? The bimetallic thermometer pointer with the direction of protecting tube connection, bimetallic thermometer can be divided into general type axial and radial. Type axial and radial difference is: axial type bimetallic thermometer: pointer vertical connection tube plate and protection. Radial type bimetallic thermometer: pointer GuanPing line connection plate and protection. You can meet the need of actual production to customize the axial and radial bimetallic thermometer. Structure bimetallic thermometer is the thread is wound into a form of thermal bimetal 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.
