Differential Pressure Transmitters - Dry

Differential Pressure Transmitters - Dry

Dry differential pressure transmitters output an analog signal (4-20 mA, 0-5 VDC, or 0-10 VDC) proportional to the pressure difference between two air taps. Use them for building pressurization, filter status, duct static pressure, fume hood, and cleanroom containment applications. ZOT stocks ACI, BAPI, Belimo, Dwyer, Senva, Siemens, and Veris — most multi-range models cover 8-10 field-selectable subranges, so one part number fits many applications.

Choosing the Right Transmitter — Three Specs to Lock

1

Pressure Range

Building / zone: ±0.1" to ±0.25" WC, bi-directional Filter status: 0-2.5" or 0-5" WC, uni-directional Duct static: 0-5" or 0-10" WC Cleanroom / fume hood: ±0.1" WC precision, bi-directional

2

Output Signal

4-20 mA: long wire runs (>500 ft), noisy environments, retrofit BAS 0-10 VDC: modern DDC, short runs, multi-input controllers 0-5 VDC: legacy 5V controllers Most stocked models offer all three, field-selectable.

3

Display

No display: lowest cost, BAS-only readout 3 or 5-color LED: at-a-glance filter or pressure status LCD: live numeric reading — best for commissioning and field troubleshooting

Tip: Use the filters on the left to narrow by brand, series, pressure range, output signal, accuracy, and display type. Looking for Buy American Act compliance? Senva P5 and ACI MLP2 / DLP series are Made in USA.
