For fixed screw bimetallic thermometer

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 by bimetallic thermometer pointer direction of the connection with the protection tube axial type, bimetallic thermometer can be divided into four radial type, universal type. The fixed screw thread connection ways can do bimetallic thermometer. In order to meet the needs of practical production, bimetallic thermometer has different installation fixed form, but fixed nipple installation is convenient, economic price, good sealing, has been the most common of the most popular, has received the affirmation from all walks of life. 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.
