How to control three-phase motor with electric contact pressure gauge
Electric contact pressure gauge controls contactor, contactor controls motor.
Electric contact pressure gauges - control intermediate relays (or electronic switches) - - control AC contactors - in the control motors
Electric contact pressure gauge contact capacity is about 1A, and the pressure gauge installation position basically has vibration phenomenon, unfavorable, so pull on contact, the first thing to consider is the pressure gauge and the measured pipe connected by a hose, pressure gauge and pressure gauge with fixed contacts to control the intermediate relay coil, often open contact of the intermediate relay to control the AC contactor coil, AC contactor main contact with motor.
