Setra 231G-MS1-2F-D Pressure Transducer

The Setra 231G-MS1-2F-D is a high-performance wet-to-wet differential pressure transducer designed for the rigorous demands of HVAC and industrial process control. This multi-configurable unit features total field-selectable pressure ranges, allowing technicians to toggle between 5, 10, 25, and 50 PSID unidirectional or ±5, ±10, ±25, and ±50 PSID bidirectional scales using a simple internal slide switch. Built with 17-4 PH stainless steel wetted parts, the dual-sensor design ensures liquid and gas compatibility while maintaining 1% full-scale accuracy across most ranges. The integrated LCD display provides instantaneous site data, showing high, low, and differential readings. For electrical integration, the device offers field-selectable 4-20 mA, 0-5 VDC, 0-10 VDC, and 1-5 VDC outputs. The NEMA 4 rated enclosure includes a hinged, captive cover and a 1/2-inch conduit connection, facilitating rapid wiring and protecting internal circuitry from harsh mechanical environments. With the jumper-selectable port swap feature, you can correct plumbing errors digitally without re-piping the 1/8-inch NPT connections.

• All-In-One Inventory Management: Consolidates eight different pressure ranges and four output signals into a single multi-configurable sensor.
• Port Swap Technology: Eliminates the need for costly physical replumbing if line connections are inadvertently reversed during differential pressure installation.
• Rugged Reliability: The Setra 231G sensor utilizes thin-film sensing technology to resist long-term drift and withstand high line pressure environments.
• Simplified Commissioning: Features a push-button zero and remote zero terminal to ensure accurate calibration post-installation without specialized tools.

• Can this unit be used for liquid level monitoring? Yes, the wet-to-wet pressure sensing capability is ideal for measuring hydrostatic level in pressurized vessels or chilled water systems.
• What happens if the line pressure exceeds the range? The Setra 231G provides robust overpressure protection, but technicians should verify that the total systemic line pressure does not exceed the 110 PSID proof pressure rating for the MS1 model.
• Is the LCD display required for operation? No, the LCD provides in-situ diagnostics, but the analog output signal functions independently for BAS and energy management integration.
