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)
- Electrical connection: With standard M16 cable gland, optional 4-pin M12 plug with A-coding
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
