Johnson Controls DPT2641-010D Transducer

The Johnson Controls DPT2641-010D is a high-precision differential pressure transducer engineered for monitoring critical environments and building automation systems. Built for professional HVACR applications, this unit features a 0 to 10 inch WC input range, making it ideal for tracking duct static pressure, filter pressure drops, and airflow monitoring in commercial air handling units. The device operates on a 12-36 VDC power supply and provides a stable 4-20 mA output signal, ensuring seamless integration with standard building management systems (BMS) and programmable logic controllers (PLCs).

Designed with a rugged, fire-retardant case, the DPT2641-010D maintains a 0.5% accuracy rating, delivering the reliable data technicians need to optimize system performance and energy efficiency. The 1/8 inch NPT female connections allow for secure plumbing into existing pneumatic lines, while the internal regulation supports use with unregulated DC power sources. With an operating temperature range of 0 to 175 degrees Fahrenheit, this very low differential pressure transducer stands up to the demanding conditions of mechanical rooms while providing repeatable, linear pressure readings.

• Precise Monitoring: The 0.5% full-scale accuracy ensures exact readings for sensitive HVAC pressure sensor applications.
• Industrial Standard Output: The 4-20 mA signal minimizes electrical noise interference over long wire runs between the sensor and the controller.
• Simplified Installation: Features easy-to-access pressure ports and electrical terminals to reduce time spent on the job site.
• Durable Construction: Housed in a fire-retardant enclosure designed to meet strict safety conformance standards.
• Versatile Compatibility: Broad 12-36 VDC input range allows for flexible power options across various control panels.

What are the primary applications for a 10 inch WC transducer?
This range is specifically suited for monitoring high-velocity duct systems, static pressure in large air handlers, and pressure drops across industrial-grade filtration banks or cooling coils.

Can this transducer be used for liquid pressure sensing?
The DPT2641 series is designed for use with air and non-combustible gases. For hydronic applications, a wet-to-wet differential pressure sensor should be used instead.

How does the 4-20 mA output benefit my control loop?
The current loop output is less susceptible to voltage drops and electromagnetic interference than 0-10V signals, providing a more robust data link for long-distance transmissions to your automation head-end.
