Examples : air conditioning and ventilation systems, clean room applications, filter control, flow control, etc.

At the pressure connection pieces, the differential pressure (+ P1↑ and P2↓ -), the positve pressure (+ P1↑) or the negative pressure (P2↓ -) are measured and indicated by the display.

The maximum permissible switching point can be adjusted at the internal differential pressure switch by means of an adjusting button.

Features

• Switching point of max. permissible valve. Changeover contact
