Dwyer Series MSX Pro Magnesense Differential Pressure Transmitter Model MSX-W20-PA

The Dwyer MSX Pro Magnesense Differential Pressure Transmitter is a high-precision device designed for critical building control applications. Building on the legacy of the Series MS2 Magnesense® II, it combines stability with versatile functionality, offering 32 configurable pressure ranges in Pa, mm w.c., or in w.c. The MSX-W20-PA model features a bidirectional pressure range of -125 to 125 Pa, dual voltage/milliamp outputs, and square root extraction for velocity/flow calculations. With its rugged design and CE certification, it ensures reliable performance in demanding environments like clean rooms, air handler units, and VAV systems.

• Bidirectional Pressure Sensing: Measures differential pressure from -125 to 125 Pa, suitable for applications requiring positive/negative pressure monitoring.
• Dual Output Signals: 4-20 mA current output (2-wire) for control systems. Optional voltage outputs (0-10 V/0-5 V) for signal verification.
• Square Root Extraction: Converts pressure signals to linear velocity/flow readings, eliminating external calculations.
• Wide Pressure Range Configurability: 32 total ranges (unidirectional/bidirectional) in Pa, mm w.c., or in w.c., adaptable to diverse applications.
• Robust Environmental Performance: Operating temperature: -4 to 158°F (-20 to 70°C). NEMA 4X (IP66) enclosure option for protection against dust and water.
• Easy Installation & Calibration: 4-wire removable terminal block for quick wiring. Digital push-button zero/span adjustments; optional 4-digit LCD for real-time readings.
