Snap-Action Electric Contact Pressure Gauge

Snap-Action Electric Contact Pressure Gauge Overview

Snap-Action Electric contact Pressure Gauge can be fitted to all 100mm and 160mm diameter pressure gauge of our range and give the advantage of indication as well as control or alarm.

Snap-Action Electric contact pressure gauge is widely used to petrochemical, chemical, metallurgical electric power fields and so forth,or applied to measurement pressure of fluid medium in the machine.

Usually, contact gauge matches with relevant electrical apparatus, for instance, relay and contactor, which is often be requested as pressure gauge with alarm or pressure gauge with switch.

The Electric contact Pressure Gauge is consisted of measurement system, indicating system, electric contact parts system, case,adjustment system, junction box (socket) and otherwise.

The principle of pressure gauge with electric contact 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 orlower limits),leading to the cut and turn-on of control system for the purpose of automatic control and alarm. We are a China pressure gauge factory, our manufacture can provide cheap contact gauge with stable quality and fast delivery time , since we have enough spare parts in stock.

Snap-action Electric Contact with Diaphragm Seal

Normal electric contact gauges combine with a separator (diaphragm seal), being electric contact diaphragm pressure gauge, accommodates strongly corrosive media, viscous & crystallographic media.

Model remark: Model of electric contact + Model of chemical seals. See “Connectors” and “Diaphragm seal” catalog.
