Radial bimetallic thermometer is the mercury?

Radial bimetallic thermometer is a kind of bimetallic thermometer, the panel and heat GuanPing line connection, its 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. We I300C, for example. Model: I300C ( WSS3B125150) Type: hot shell bimetallic thermometer structure: radial type cover circle: flange type, tray type panel material: stainless steel SS304 tooth head: 1/2 & quot; NPT other optional surface diameter: 80 mm heat pipe diameter: 6. 35 mm heat pipe length: 150 mm ( 50 - Optional) around 1200 mm. Temperature range: 0 - 100C ( Can be customized) Accuracy: & plusmn; 1. Protection grade: 5% table: glass IP65 thus, radial bimetallic thermometer is not mercury.
