∆P PRESSURE INDICATOR

GENERAL CHARACTERISTICS
Differential pressure monitoring of air or non aggressive gas.
The indicator is connected to the pressure circuit by nozzle connections. A diaphragm and a calibrated spring transfer, by an amplifying mechanism, the differential pressure changes to the needle of the graduated scale.
All components are enclosed into a sealed IP65 protection box.
