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

The Setra 231G-MS1-2F-N represents the industry standard for wet-to-wet differential pressure monitoring in hydronic systems and HVAC process control. This multi-configurable transducer is an all-in-one solution for contractors, featuring 8 field selectable pressure ranges and 4 field selectable analog outputs (4-20 mA, 0-5 VDC, 0-10 VDC, and 1-5 VDC). Built around a highly reliable piezoresistive sensor, it handles unidirectional ranges of 5, 10, 25, and 50 PSID, as well as bidirectional ranges from ±5 to ±50 PSID. The NEMA 4 rated die-cast aluminum enclosure with a hinged captive cover ensures internal components remain protected in harsh mechanical rooms. To simplify installation, the unit includes a 1/8-18 NPT female process connection and a 1/2-inch conduit opening for secure wiring. With its push-button zeroing and jumper-selectable port swap feature, this Setra differential pressure transmitter allows for rapid field adjustments without the need for additional plumbing or extensive downtime.

• Broad Compatibility: Selectable ranges and outputs ensure one unit can substitute for multiple fixed-range sensors in the field.
• Reduced Rework: The "Port Swap" feature allows you to correct "HI" and "LO" piping errors via software, eliminating the need to replumb lines.
• Rugged Reliability: 17-4 PH stainless steel wetted parts are compatible with various liquids and gases commonly found in energy management systems.
• Ease of Commissioning: Field-accessible push-button zero and remote zero capability simplify the calibration process after installation.

• How do I correct a reverse pressure installation? Use the internal port-swap jumper to flip the high and low sensor readings electronically without disconnecting any physical piping.
• What is the maximum line pressure for the MS1 model? The 231G-MS1 series is designed for a maximum line pressure of 50 PSID.
• Can this sensor be used for water flow measurement? Yes, it is optimized for tracking pressure drops across pumps, chillers, and filters to calculate real-time flow data.
