Setra Systems 231GMS15VD Differential Pressure Transducer

Product Description

The SETRA SYSTEMS 231GMS15VD is a differential pressure transducer designed for wet media applications, supporting both unidirectional and bidirectional pressure measurement. It features a multi-range configuration with selectable full-scale ranges of 0-5 psi, 0-10 psi, 0-25 psi, and 0-50 psi, giving technicians flexibility across a wide range of system pressures. An integrated LCD display provides on-site pressure readings without additional instrumentation. Manual range selection allows field configuration to match the specific application. This unit is suited for HVAC, industrial, and process monitoring installations where direct contact with liquid or wet media is required.

The 231GMS15VD is intended for applications where the sensing element contacts wet or liquid media, including chilled water systems, hydronic heating loops, compressed air with moisture, and similar fluid-based pressure monitoring scenarios. Its multi-range capability and bidirectional measurement make it appropriate for both supply and return side monitoring in commercial and light industrial systems. Licensed HVAC technicians and instrumentation technicians are the primary installers for this type of device.

Key Features

• Selectable pressure ranges: 0-5 psi, 0-10 psi, 0-25 psi, and 0-50 psi
• Wet media compatibility for direct liquid contact applications
• Supports both unidirectional and bidirectional pressure measurement
• Integrated LCD display for local pressure indication
• Manual range selection for field configuration without additional tools
• Compact transducer form factor suitable for panel or inline mounting

Compatibility

Designed as an OEM-style replacement or direct-install differential pressure transducer for wet media pressure monitoring applications in commercial HVAC and industrial process systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or instrumentation technician familiar with pressure sensing devices and applicable local codes. Isolate and depressurize the system before connecting or disconnecting the transducer from any wetted port. Verify that process media is compatible with the transducer wetted materials before installation. Follow all applicable electrical codes, including NEC requirements, when wiring the signal and power connections.
