DP140 Series offers an excellent price-to-performance ratio
and meets the requirements in all typical HVAC applications.
The DP140 is a low differential pressure transducer that
uses a dead-ended capacitive sensing element and requires
minimal amplification. The DP140 delivers ±1% full-scale
(FS) accuracy with ±0.25% and ±0.5% accuracy options with
pressure ranges from 0.1 in. W.C. up to ±25 in. W.C. The
DP140 has a small footprint and an AC power option.
