Description
The Johnson Controls DP140025U21D is a precision low differential pressure transducer engineered for demanding HVAC and building automation applications. Designed to deliver reliable, accurate pressure measurement across a 0–25″ water column (wc) unidirectional range, this transducer is an ideal solution for monitoring duct static pressure, filter differential pressure, and airflow in commercial and industrial systems.
Key Features
- Pressure range: 0–25″ w.c. (unidirectional)
- Output signal: 4–20 mA for long-distance signal transmission and noise immunity
- Accuracy: ±0.5% of full scale for precise, dependable readings
- Process connection: 1/4″ push-on barb fitting for quick, tool-free installation
- IP67-rated housing for protection against dust ingress and temporary water immersion
Performance & Accuracy
With a ±0.5% full-scale accuracy rating, the DP140025U21D delivers consistent, repeatable measurements critical for building automation systems (BAS), energy management, and HVAC controls. The 4–20 mA analog output signal ensures excellent noise rejection over long cable runs, making it well-suited for large commercial buildings and industrial facilities.
Installation & Connectivity
The 1/4″ push-on barb fitting process connection simplifies field installation, reducing labor time and the need for specialty tools. The unidirectional design is optimized for single-direction pressure sensing, keeping setup straightforward and reliable.
Durability & Environmental Protection
Housed in an IP67-rated enclosure, this transducer is protected against solid particle ingress and short-term immersion in water — making it suitable for installation in mechanical rooms, air handling units, and other environments where moisture and contaminants are a concern.
Typical Applications
- Duct static pressure monitoring
- Air filter differential pressure measurement
- Airflow measurement and control
- Building automation and energy management systems
- Commercial HVAC air handling units (AHUs)
- Clean room and laboratory pressure monitoring
