DP140 Series Low Differential Pressure Transducer

The Johnson Controls Low Differential Pressure Transducer 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. Applications HVAC systems Air flow stations Variable Air Volume (VAV) or fan control Filter status Static duct and cleanroom pressures Features Excellent price-to-performance ratio Reduced installation costs ±0.25%, ±0.5%, ±1% FS accuracy options 24 VDC or 24 VAC excitation Voltage or milli-amp analog outputs Reverse wiring protection Internal regulation Fire retardant case, UL 94 V-0 approved CE and RoHS compliant
