Setra 2301050PD3V11B Manifold

The Setra 2301050PD3V11B is a high-performance wet-to-wet differential pressure transducer designed for precise monitoring in demanding HVACR and industrial fluid systems. Featuring a 0 to 50 PSID unidirectional pressure range, this unit utilizes an all-stainless steel capacitive sensor that delivers response times up to 20 times faster than traditional oil-filled sensors. Unlike dual-sensor designs that calculate differential values, the Model 230 employs a single diaphragm design to measure true differential pressure with ±0.25% full scale accuracy, effectively eliminating line pressure errors. This specific configuration includes a factory-assembled 3-valve manifold machined from solid brass, which simplifies commissioning and maintenance by allowing for easy zeroing and system isolation without the risk of internal leaks from pipe connections.

Built for field reliability, the sensor is housed in a NEMA 4 (IP65) rated enclosure and provides a linear 4-20 mA output compatible with most building automation systems and industrial controllers. The standard Viton bleed screw seals ensure chemical compatibility with a wide variety of gases and liquids, making it a staple for technicians managing chilled water loops, process control, and filter status monitoring. The 2301-050PD-3V-11-B also features adjustable zero and span potentiometers and is CE and RoHS compliant for international standards.

• True Wet-to-Wet Measurement: Single diaphragm construction avoids the common inaccuracies found in dual-sensor differential calculations.
• Rapid Response: Capacitance technology provides near-instantaneous signal feedback for dynamic system control.
• Integrated Manifold: The machined 3-valve assembly reduces installation labor and minimizes potential leak points in the fluid path.
• Rugged Durability: NEMA 4 housing and 17-4 PH stainless steel wetted parts withstand harsh mechanical room environments.
• Stable Signal: Conditioned electronic circuitry maintains linear output across a wide temperature range (30°F to 150°F compensated).

Common Questions

What are the primary advantages of the 3-valve manifold for this transducer?
The manifold facilitates safe maintenance by allowing the technician to isolate the sensor from the process lines and equalize pressure to verify zero. This avoids the need for external plumbing and reduces the risk of air entrapment in the lines.

Can this sensor be used for gas applications as well as liquids?
Yes, the 17-4 stainless steel and Viton wetted parts are compatible with any gases or liquids that do not react with those materials, though it is primarily optimized for wet-to-wet water pressure monitoring.

Does line pressure affect the accuracy of the 50 PSID measurement?
No, the single diaphragm design is inherently resistant to line pressure effects up to the maximum rated pressure, ensuring the 0.25% accuracy remains consistent regardless of static system pressure.
