The HE 5421 is a universal measuring transducer especially for small differential pressures (< 100 mbar). The actual differential pressure is indicated digitally with 3½-digits. The device has two switching thresholds for monitoring and control purposes, e.g. for the ΔP-dependent dedusting in industrial dust extraction technology. An additional threshold is used for monitoring a maximum differential pressure. The switching state of the relays is indicated with LEDs. The device is dust-proof and approved for operation in explosion zone 22
