Setra 2301050PD2F11B Transducer

The Setra 2301050PD2F11B is a high-performance wet-to-wet differential pressure transducer designed for precise monitoring of liquid or gas pressures in demanding HVAC and industrial systems. Built on the rugged Model 230 platform, this unit features a 0 to 50 PSID unidirectional pressure range and provides a stable 4-20 mA output for seamless integration into building automation systems and PLCs. Engineered with an all-welded stainless steel sensor structure, it handles differential pressures without required internal O-rings, mitigating potential leak paths. The 1/4" NPT female pressure fittings and standard Viton bleed screw seals facilitate easier air venting during commissioning, ensuring high responsiveness in chilled water systems or process control applications. This model is a direct cross-reference for the DPT2301-050D, offering the high burst pressure protection and 0.25% FS accuracy necessary for professional-grade hydronic balance and pump monitoring.

• All-Welded Stainless Steel Sensor: Provides excellent chemical compatibility and eliminates internal O-ring failure risks.
• High Overpressure Capability: Protects the internal sensing element against pressure surges common in heavy-duty hydronic systems.
• Viton Bleed Screws: Allows for safe and effective air elimination in liquid lines to maintain signal integrity and measurement precision.
• Standard 4-20 mA Loop: Enables reliable long-distance signal transmission with high resistance to electrical noise in industrial pressure monitoring environments.
• Drop-in Replacement: Verified as identical to DPT2301-050D for simplified procurement and maintenance workflows.

How do I handle air trapped in the lines of a Setra 230 series?
Utilize the integrated Viton bleed screws located on the side of the differential pressure sensor manifold. Bleeding the lines ensures the liquid makes direct contact with the diaphragm for accurate PSID measurement.

What is the maximum line pressure for the 50 PSID model?
While the differential range is 50 PSID, these transducers are typically rated for high static line pressures. Always verify that your system's maximum static pressure does not exceed the sensor's specified limit to prevent zero-shift.

Can the 2301050PD2F11B be mounted in any orientation?
For optimal HVAC pressure sensing, it is recommended to mount the unit with the pressure ports facing downward to prevent sediment buildup and to assist in the natural venting of air through the bleed valves.
