The Dwyer MSX Pro Pressure Transmitter (MSX-20W-PA) is a versatile Magnesense differential pressure sensor designed for building control applications, monitoring differential pressure, air velocity, and volumetric flow. Built on the stability of the MS2 Magnesense II series, it simplifies configuration with 32 selectable pressure ranges (Pa, mm w.c., in w.c.) in unidirectional/bidirectional modes.
Monitors differential pressure, air velocity, and volumetric flow in building systems with ±1% FSO accuracy across 32 pressure ranges (Pa, mm w.c., in w.c.).
Linear pressure output or velocity output with square root extraction for flow calculation. Dual signals: 4-20 mA (2-wire) and selectable 0-10 V/0-5 V (3-wire) for control and signal verification.
10-36 VDC (2-wire) or 17-36 VDC/21.6-33 VAC (3-wire) power input. Features 1/2" NPS thread electrical entry and orientation-independent mounting.
4-digit LCD with 180° rotatable display for optimal visibility in any installation. Optional toolless terminal block for quick wiring.
UL94 V-0 fire rating and plenum-rated materials for hazardous environments. Pressure limits: Up to 3.6 psi (operation) and 6 psi (burst) for select ranges.
Ideal for filter monitoring, clean room pressure control, duct static pressure, and VAV system airflow.
