Setra 2301025PD3V11B Manifold

The Setra 2301025PD3V11B is a high-precision wet-to-wet differential pressure transducer designed for rigorous HVACR and industrial applications. This Setra 230 series unit features a 0 to 25 PSID unidirectional pressure range and utilizes a single-diaphragm capacitive sensor to provide ±0.25% FS accuracy. Unlike dual-sensor systems, this single-diaphragm construction eliminates line pressure effects, ensuring reliable DP pressure monitoring in chilled water, process control, and pump systems. The integrated 3-valve manifold, machined from high-quality brass, simplifies installation and maintenance by allowing for easy zeroing and bleeding without breaking process lines. This model is identical to DPT2301-025D-V and provides a standard 4-20 mA output for seamless integration into 2-wire control loops.

Key Benefits:

• Enhanced Accuracy: True wet-wet differential pressure measurement with a single-diaphragm design that outperforms dual-sensor calculated DP.
• Robust Construction: NEMA 4 (IP65) rated housing and 17-4 stainless steel wetted parts provide durability in demanding environments.
• Reduced Leak Risk: The integral 3-valve manifold features no internal process connections, significantly reducing potential leak points.
• Chemical Resistance: Standard Viton bleed screw seals ensure compatibility with a variety of liquids and gases.
• Fast Response: Capacitance-based sensing technology delivers rapid response times, up to 20x faster than traditional oil-filled sensors.

Common Questions:

Which media is compatible with the 2301025PD3V11B?
This wet-wet pressure transmitter is compatible with any liquid or gas that is non-corrosive to 17-4 PH stainless steel, 300 series stainless steel, and Viton/Silicon seals.

How do I bleed air from the system?
The unit includes dedicated Viton bleed screws. During installation, open the manifold shunt valve (Valve C) while keeping high/low valves closed to wet the system, then slowly open the bleed screws until liquid flows without air bubbles.

Can the output signal be adjusted in the field?
Yes, the internal electronics feature accessible zero and span trim POTs for fine-tuning the 4-20 mA signal after the unit is mounted in its permanent vertical position.
