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

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

Product Introduction

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.

Product Features

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.
