Electric contact pressure gauge pressure gauge, Hangzhou, Hangzhou

electric contact pressure gauge is used to measure copper and copper alloy corrosion can not afford the gas, liquid medium positive or negative pressure, and when the pressure reaches a predetermined value a signal connected to control circuit, the auto was the purpose of the alarm control.
Electrical contacts in electrical contact device signal pins, with a permanent magnet can be adjusted, to increase contacts suction, speed up access to action, so that access to reliable contacts, eliminating the arc, which can effectively avoid the instrument as a result of environmental vibration or media pressure fluctuation caused by the frequent contacts off. Electrical contacts with the action so reliable, long life, greater power contact switch, etc..
