Setra 231G-MS3-2F-N Multi-Configurable Wet-to-Wet Differential Pressure Sensor

Description

The Setra 231G-MS3-2F-N is a professional-grade, multi-configurable wet-to-wet differential pressure sensor engineered for demanding HVAC, building automation, and industrial process monitoring applications. Designed to measure liquid-to-liquid differential pressure across a wide range of selectable spans, this sensor delivers accurate, reliable readings in both unidirectional and bidirectional configurations.

Pressure Range Options

• Unidirectional ranges: 25, 50, 125, and 250 PSID
• Bidirectional ranges: ±25, ±50, ±125, and ±250 PSID

Key Features

• Multi-configurable design allows field selection of pressure range without replacing the sensor
• Wet-to-wet differential measurement — ideal for liquid pressure monitoring across filters, heat exchangers, coils, and pumps
• 1/8-18 NPT female pressure connection (standard) for straightforward plumbing integration
• Conduit version housing for secure, code-compliant wiring in commercial and industrial environments
• No display (transmitter output only) — clean installation for panel or remote monitoring setups
• Setra’s proven capacitive sensing technology for long-term stability and accuracy

Typical Applications

• Chilled water and hot water system differential pressure monitoring
• Filter and strainer pressure drop measurement
• Heat exchanger and coil performance monitoring
• Pump differential pressure verification
• Building automation and BAS integration
• Industrial process control and monitoring
