WSSX-512 Electric Contact Bimetal thermometer, the protective tube, joints, and locking bolts of the dual-general thermometer are all made of 1Cr18Ni9Ti. The case is stretched and formed by aluminum plate and the surface is black electrophoresed. The cover and case are sealed and locked with a double-layer rubber ring thread. Due to the structure, the overall water-proof and anti-corrosion performance of the instrument is good. The radial type instrument adopts the elbow structure, which is novel in appearance, light and beautiful.
The bimetal thermometer is an on-site detection instrument used to measure medium and low temperatures. It can be used to directly measure the temperature of liquefaction and gas. Compared with glass mercury thermometers, it has the advantages of no mercury hazard, easy reading, firmness and durability.
WSSX series electric contact bimetal thermometers are equipped with electric contact devices, namely mechanical electric contacts. When the temperature of the measured medium changes, the thin shaft on the free end and the steering transmission mechanism drive the pointer and the movable contact to rotate, and the temperature change value is indicated on the dial. Point) The moment of contact or disconnection, which causes the relays and contactors in the circuit system to act to achieve automatic control and alarm purposes. It should comply with the JB/T8803 1998 standard.
