WSS series and WSSX series bimetallic thermometer have what differentiation?

The following instrument with everybody to know about the WSS series and the difference between WSSX series bimetallic thermometer. WSS series bimetallic thermometer type is hot set type bimetallic thermometer. WSS series 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. WSS series bimetallic thermometers are wound into threaded type thermal 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. WSSX series bimetallic thermometer types are electric contact bimetallic thermometer. WSSX series bimetallic thermometer, electric contact bimetallic thermometer is the use of lead contact changes when temperature changes, when touch point contact with the upper and lower limits or disconnected at the same time, make the circuit of relay action, to control and alarm automatically. Electric contact bimetallic thermometer used in production field of temperature control and alarm automatically. - direct measurement of all kinds of production process Within the scope of 80 ~ 500 ℃, the steam. The characteristics of the electric contact bimetallic thermometer: scene display temperature, intuitive and convenient; With functions of automatic cut off power and alarm; Safe and reliable, long life; Many kinds of structure forms, can meet different requirements.
