WSS411- series bimetallic thermometer is an on-site inspection of industrial instrumentation, reading out the measured gas, liquid and steam temperature reading directly from disc, used in petrochemical, mining, metallurgy, textile, military, pharmaceutical, food and other departments , the low-temperature environment temperature and control field. The series has a responsive, easy to read, anti-vibration, no harmful mercury, stable performance, long life, shell protection grade IP65, etc., can substitute industrial glass mercury thermometer and widely used.

Second, the structure

Bimetal thermometer bimetal temperature sensing element, the support tube, connecting means, the indicator disc and other components. Bimetal temperature sensing element multi-ring straight double metal spiral, one end fixed and the other end (free end) is connected to the mandrel, when the temperature changes, the temperature sensing element free end of the rotation, the spindle drive pointers in It indicates the temperature of the measured medium on the indicator disc. Bimetallic thermometer form of the structure is divided into axial type (angle), radial type (diameter), universal type three; their functions are divided into common type (single index), electric contacts, remote function, with luminous four.
