Setra 231G-MS3-2F-D Pressure Transducer

The Setra 231G-MS3-2F-D is a high-performance wet-to-wet differential pressure transducer engineered for demanding hydronic and HVAC applications. Designed for maximum field flexibility, this multi-configurable pressure sensor features 8 switch-selectable ranges, covering 25, 50, 125, and 250 PSID in both unidirectional and bidirectional modes. This eliminates the need to carry multiple single-range units, simplifying inventory and ensuring on-site compatibility for pump monitoring and heat exchanger pressure drop measurements.

Encased in a rugged NEMA 4 enclosure with a powder-coated die-cast aluminum housing, the 231G-MS3-2F-D provides superior protection in harsh mechanical rooms. The integrated LCD display allows for immediate local monitoring of high-side, low-side, and total differential pressure. This unit features 1/4" NPT internal pressure connections and a piezoresistive 17-4 PH stainless steel sensor, ensuring long-term stability and resistance to process media. With field-selectable 4-20 mA current and 0-5, 0-10, or 1-5 VDC voltage outputs, this differential pressure transmitter integrates seamlessly into any Building Automation System (BAS) or PLC setup.

• Field-Selectable Range & Output: 8 selectable pressure ranges and 4 analog outputs ensure compatibility with any controller or system requirement.
• Local Diagnostics: Integrated 4-digit LCD display provides real-time pressure data, facilitating faster system balancing and troubleshooting.
• Reliable Push-Button Zero: External zero-adjustment and remote zero-input simplify commissioning and periodic maintenance.
• Durable Construction: NEMA 4 rated enclosure and 17-4 stainless steel wetted parts provide industrial-grade protection against moisture and corrosive media.
• Simplified Wiring: Features a 1/2" conduit connection and terminal block for reliable electrical termination.

• How do I configure the pressure range on the Setra 231G-MS3-2F-D? Range selection is managed via internal slide switches located under the hinged NEMA 4 cover, allowing for quick adjustments between 25 and 250 PSID.
• Can this sensor be used for both liquid and gas? Yes, the 17-4 PH stainless steel wetted parts are compatible with any liquid or gas media that does not react with high-grade stainless steel.
• What supply voltage is required for the 4-20 mA output? The unit operates on a 12-30 VDC power supply, with reverse excitation protection for safe installation.
