Description
. . . . . The Johnson Controls DP140001B21D is a low differential pressure transducer from the DP140 Series. Johnson Controls lists this exact code as a low-pressure differential pressure transducer, bidirectional, ±1 in. W.C., 24 VDC or 4 mA to 20 mA - so it measures pressure in both directions either side of zero and reports it as a 4-20 mA current-loop signal.
The DP140 uses a dead-ended capacitive sensing element that requires minimal amplification, which gives the series its long-term stability and low drift. Johnson Controls rates the series at ±1% full-scale accuracy, with ±0.5% and ±0.25% FS accuracy options, across pressure ranges from 0.1 in. W.C. up to ±25 in. W.C. Every unit is factory tested and calibrated before shipment.
Typical applications: HVAC systems, air flow stations, Variable Air Volume (VAV) and fan control, filter status monitoring, and static duct and cleanroom pressures. The bidirectional ±1 in. W.C. range suits low-pressure work such as space pressurisation and cleanroom differentials, where flow can reverse.

Media compatibility - important: use the DP140 with air or non-conducting gases only. Johnson Controls warns that use with liquids or corrosive gases will damage the unit.
A note on the final character: in this model code the trailing D selects the accuracy option, but Johnson Controls does not publish a letter-by-letter breakdown of that character, so we are not stating a figure for it. If you need a specific accuracy class confirmed, contact us and we will check the unit label before you order.
Not sure whether you need bidirectional or unidirectional, or a voltage output instead of 4-20 mA? The DP140 range covers 0-5 VDC, 0-10 VDC and 4-20 mA outputs and a wide span of ranges - tell us your application and we will match the right code.. Johnson Controls. Johnson Controls. DP140001B21D.
