Pressure Gauges

Electrical Contact

MICRO pressure gauges with electrical contacts, these incorporate a mechanical magnetic snap action contact mechanism in to an analogue pressure indicator. They generate ON and OFF electrical signals at preset value of measurement. These signals can be used to activate or deactivate buzzer, alarm, pilot lamp, control motor, pump, valve or any other process which requires controlling. These eliminate the need of separate switches for such controlling of equipments. Point of actuation is adjustable between 10% to 90% of FS.
