Dwyer Magnesense MS-111 Differential Pressure Transmitter

Product Introduction

The Dwyer Magnesense MS-111 is a versatile differential pressure transmitter engineered for precise monitoring of micro pressure, vacuum, air velocity, and volume in industrial systems. Leveraging patented magnetic sensing technology, this transmitter combines field-configurable functionality with rugged durability, making it ideal for HVAC, building automation, and process control applications.

Product Features

Adaptive Sensing Range: Selectable ranges (1", 2", 5" w.c. / 250–1250 Pa) with ±1% full-scale (FS) accuracy for critical measurements.

Dual Output Signals: 4–20 mA (2-wire) and optional 0–5/10 VDC (3-wire) for seamless integration with PLCs, BMS, and local monitoring systems.

Field Configurability

Metric/imperial unit selection (in. w.c., Pa, kPa) via digital push buttons.

Adjustable damping (0.5–15 sec.) to filter noise in turbulent environments.

Square root output for direct flow calculation with Pitot tubes or orifice plates.

Rugged Design: NEMA 4X (IP66) enclosure protects against dust, water, and harsh conditions.
