The working principle of pressure switch

Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China.

such as chains, sprockets and plate wheels, pulleys, gearboxes, motors, couplings, gears and racks. Our product range also covers locking assemblies (clamping elements/locking device), taper bushes, QD bushes, bolt-on hubs, torque limiters, shaft collars, motor bases and motor slides, chain detachers, chain guides, universal joint, rod ends and yokes. 

China couplings manufacturer & exporter, we specialize in: chain couplings, Jaw couplings, flexible couplings, HRC couplings, NM couplings, MH couplings, Pin coupling, Spacer Coupling, Flange Coupling, Sleeve Coupling, nylon sleeve coupling.

Timing Belt Pulleys

Pressure switch pressure sensor with high precision, high stabilityand transmission circuit, the special CPU modular signal processing technique for detection, the pressure signal media display, alarm and control signal output. Pressure switch can be widely used in petroleum, chemical, metallurgy, electric power, water supply and other fields for various gas and liquid gauge pressure, absolute pressure measurement control instrument is the intelligent controlof industrial field ideal. Pressure switch is widely used in the fields ofaerospace and military industry, such as M1A1 tanks, Apollo, the Boeing 747 and Airbus A320, F22, F117 and other productsmanufacturing.

Working principle

The working principle of pressure switch: when the system pressureis higher or lower than the safety pressure rated, occurrence of discinstantaneous motion sensor, through the connecting rod to drive switch connector on or off, when the pressure drops to or ratedrecovery value, disc instant reset switch automatically reset, orsimply when the measured pressure exceeds the rated value, thedisplacement of the free end of the elastic element, directly or after comparing push switch element, change the switching element to control the on-off state of the measured pressure purposes.Pressure switch elastic element adopts the single coil spring pipe,the diaphragm, bellows and bellows.
