Compact differential pressure transmitter for positive or negative differential pressures in basic applications

Special features

• ± measurement ranges and asymmetric measurement ranges

• Either with 1 fixed measurement range or toggling between 4 different measurement ranges (can be selected via DIP switches, optional)

• Suitable for top-hat rail mountingand wall surface installation

• Selectable output signal 0/2 .. 10 V, 0/4 .. 20 mA or 0 .. 5 V

• Can be calibrated

• Zero-point calibration via an external signal reduces maintenance costs

• The adjustable limit switch permits the connection of, e.g. ventilators or signalling devices, and saves additional wiring (optional)

This compact differential pressure transmitter is particularly suited to filter and pressure monitoring applications in the heating, air-conditioning and ventilation industries. 

Options

• The instrument is available with an factory calibration certificate or calibration certificate according to DKD-R 6-1.

• An optional display allows measurement values to be read directly on-site in Pa or kPa. 

• An optional time constant (up to 4s) allows the instrument to generate an attenuated output signal, even under fluctuating pressure conditions.

• To reduce wiring costs, the instrument is also available in a version with two-wire technology (optional).

• Pressure ports also as push-in fittings on request
