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 circuits and the
alarm was the purpose of automatic 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..
