Setra 2301050PB3V11B Transducer

The Setra 2301050PB3V11B Transducer is a professional-grade solution for technicians requiring high-accuracy wet-to-wet differential pressure monitoring. Built specifically for demanding HVACR and industrial hydraulic environments, this model features a single diaphragm sensor design. Unlike dual-sensor configurations that calculate differential pressure by comparing two separate readings, this all stainless steel capacitive sensor provides a direct measurement, effectively eliminating the common errors associated with line pressure fluctuations. Operating on a bi-directional range of ±50 psid, it delivers a precise 4-20 mA output signal, ensuring seamless integration into modern building automation systems and process controllers.

Engineered for maximum field reliability, the Setra Model 230 includes a factory-installed 3-valve manifold. This machined brass assembly simplifies installation and periodic maintenance by allowing for easy zero-point checks and sensor isolation without breaking the process lines. The NEMA 4 rated housing and Viton bleed screw seals ensure the unit stands up to moisture and corrosive media, while the lack of internal oil fill means a response time up to 20 times faster than liquid-filled alternatives. For contractors looking for stable ±0.25% FS accuracy in liquid or gas applications, this transducer provides the technical performance required for critical system balancing and flow measurement.

• Precise Differential Measurement: Single diaphragm construction ensures ±0.25% full scale accuracy without line pressure effect.
• Integrated 3-Valve Manifold: Simplifies field commissioning and allows for easy maintenance and sensor isolation.
• Fast Response Sensor: Capacitive technology provides rapid signal feedback, essential for dynamic pressure transducer control loops.
• Rugged Environmental Protection: The NEMA 4/IP65 enclosure protects sensitive electronics from moisture and debris.
• Broad Media Compatibility: 17-4 PH stainless steel wetted parts are compatible with a wide variety of liquid and gas systems.

How do I wire the Setra 230 for a 4-20 mA loop?
This model is a true 2-wire current output device. Ensure you observe proper polarity when connecting to your 9-30 VDC power supply and receiver. The 4-20 mA output is factory calibrated for high precision and typically drives a load up to 1000 ohms.

Is the ±50 psid range fixed or adjustable?
The Setra 2301050PB3V11B is a fixed-range ±50 psid unit. While it includes zero and span trim potentiometers for minor field adjustments, the fundamental range is set at the factory to maintain optimal linearity and accuracy.

What is the benefit of the single diaphragm over dual sensors?
Dual-sensor units often struggle with line pressure shifts because they rely on subtracting two high-pressure readings to find a small difference. The single diaphragm design in this transducer responds only to the pressure difference across the diaphragm, yielding much higher stability and reliability in wet-to-wet applications.
