Description

Electronic Δp - SENSOR - ALARM unit with differential pressure sensor, relay output and optical signal.

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

At the pressure connections, the differential pressure (+ P1↑ und P2↓ -), the positve pressure (+ P1↑) or the negative pressure (P2↓ -) is measured.

The switching point can be adjusted at the integrated differential pressure sensor by means of an adjustment screw within 20% to 100% of the measuring range. The relay output - controlled by the sensor and equipped with a high current contact for a long service life - is additionally provided with an electronic damping, assuring safe switching operations independent of permanent air turbulences.

A red LED lights up, when the adjusted switching point is reached.
