Электрический контактный сухой вакуумный

Electric contact pressure gauge can be fitted to all 100mm and 160mm diameter instruments of our range and give the advantage of indication as well as control or alarm.
Snap-Action Electric contact pressure gauges are widely used to petrochemical, chemical, metallurgical electric power fields and so forth,or applied to measurement pressure of fluid medium in the machine.
Usually, electric contact pressure gauge matches with relevant electrical apparatus, for instance, relay and contactor. The instrument is consisted of measurement system, indicating system, electric contact parts system, case,adjustment system, junction box (socket) and otherwise. The principle is that under the conditions of medium pressure, bourdon tube will show the measured value in the dial by gear wheel equipment. In the meanwhile,the pointer of instrument will make dynamic contact touch or cut with static one (upper limits or lower limits),leading to the cut and turn-on of control system for the purpose of automatic control and alarm.
