Setra 231G-MS2-2F-N Pressure Transducer

The Setra 231G-MS2-2F-N is a rugged, wet-to-wet differential pressure transducer engineered for demanding HVACR liquid and gas monitoring. Designed for the field technician, this multi-configurable unit features field-selectable pressure ranges covering 10, 20, 50, and 100 PSID in unidirectional mode, and ±10, ±20, ±50, and ±100 PSID in bidirectional mode. Its all-cast aluminum NEMA 4 enclosure houses a 17-4 PH stainless steel piezoresistive sensor, providing high burst pressure protection and field-selectable analog outputs (4-20 mA, 0-5 VDC, 0-10 VDC, and 1-5 VDC). The 1/8-18 NPT female process connections and 1/2-inch conduit version ensure seamless integration into existing Building Automation Systems (BAS) and energy management loops. With featured push-button zero and remote zero capabilities, this Setra 231 series transmitter eliminates the need for multiple fixed-range sensors, reducing inventory complexity while maintaining ±1.0% FS accuracy on standard ranges.

• Versatile Configuration: Toggle between 8 different pressure ranges and 4 output signals using internal slide switches for immediate adaptation to site conditions.
• Durable Construction: The NEMA 4 rated housing and stainless steel wetted parts provide superior resistance in harsh mechanical rooms and industrial environments.
• Streamlined Installation: Features a hinged captive cover for easy access to internal circuitry and dual sensors that prevent internal leaks compared to traditional manifold setups.
• System Reliability: High proof pressure ratings and a robust 17-4 PH stainless steel diaphragm ensure long-term stability in pumping and chilled water applications.

Can I use this for both water and air?
Yes, the Setra 231G-MS2-2F-N is compatible with any liquids or gases that are non-corrosive to 17-4 PH stainless steel, making it ideal for hydronic systems and steam applications.

Does this unit require a specific mounting orientation?
While the 231 series is robust, it is recommended to mount the unit with the pressure ports facing downward; however, the push-button zero feature allows you to calibrate out any positional offsets after installation.

What happens if the line pressure exceeds the range?
The MS2 sensor configuration is designed with a high proof pressure (up to 220 PSID), but always ensure the combined static and differential pressure does not exceed the burst rating to prevent sensor damage.
