Johnson Controls DPT2301-100DV Pressure Transducer

The Johnson Controls DPT2301-100DV is a high-performance wet/wet differential pressure transducer engineered for demanding HVACR and industrial process monitoring. Designed for precise differential pressure measurement in liquid systems, this unit features a 0 to 100 PSID range and a standard 4-20 mA output signal, ensuring seamless integration with building automation systems (BAS) and programmable logic controllers. The inclusion of an integrated 3-valve manifold simplifies installation and maintenance by allowing for easy zeroing and isolation without breaking process lines. Built to withstand rugged environments, it maintains high accuracy across an operating temperature range of 0°F to 175°F. This transducer is the professional choice for monitoring chiller efficiency, pump performance, and filter status in chilled water or heating loops. Its robust NEMA 4/IP65 housing and all-stainless steel wetted parts provide long-term reliability in applications involving compatible liquids and gases, preventing common issues like sensor drift or mechanical fatigue in high-vibration environments.

• Streamlined Installation: The factory-installed 3-valve manifold reduces leak points and saves labor time during field setup.
• Broad Compatibility: All-stainless steel wetted materials support use with a variety of non-corrosive liquids and gases.
• Standardized Signal: The 4-20 mA current loop provides excellent noise immunity for long cable runs in mechanical rooms.
• Accurate Monitoring: Specifically designed for wet-to-wet applications including heat exchangers, hydraulic systems, and pump differential monitoring.

Common Questions

What is the advantage of a wet/wet transducer over a dry/dry model?
A wet/wet differential pressure transducer like the DPT2301-100DV is designed to handle liquid on both the high and low pressure ports, making it ideal for hydronic systems. Dry/dry models are restricted to non-condensing air or gas and will fail if exposed to liquid media.

Can the 3-valve manifold be used for field calibration?
Yes, the integrated manifold allows a technician to isolate the sensor from the process and open the equalizer valve to verify the zero pressure signal, ensuring the system maintains its 0.25% full-scale accuracy over time.

Is this unit compatible with glycol-based cooling systems?
Absolutely. The stainless steel construction and internal diaphragms are fully compatible with water, ethylene glycol, and propylene glycol mixtures commonly found in commercial HVAC loops.
