Bimetallic thermometer specifications have?

Bimetallic thermometer, it can directly measure the - in the process of production 50 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. 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. To cooperate with all kinds of casing installation, satisfies the requirement of different pressure levels. Bimetallic thermometer specifications are as follows: 1. Nominal diameter: such as 60, 100, 150; Φ Φ Φ 2, accuracy, such as 1. 0 and 1. 5; 3, process connection thread: such as M20 * 1. 5,1/2NPT; 4, installation methods: axial and radial, universal; 5, the thermal response time & le; 40年代; 6, protection grade: IP65; 7, the temperature measurement range; 8, insert length.
