DW (pressure switch)
The Δp - SWITCH device is used in many ranges of application because of ist favorable cost-performance ratio.
Examples: air conditioning and ventilation systems, clean room applications, filter control etc.
At the pressure connection pieces, the differential pressure (P1+ and P2-), the positve pressure (+ P1) or the negative pressure (P2 -) is measured.
The switching point can be adjusted at the internal adjusting knob with guide value scale.
