Dwyer Magnesense MS2 Differential Pressure Transmitter
Product Introduction
The Dwyer Magnesense MS2 Differential Pressure Transmitter elevates
industrial pressure monitoring with advanced Hall Effect sensing
technology and enhanced functionality. Building on the legacy of
the original MS Series, this second-generation transmitter
streamlines installation with field-selectable ranges, dual output
signals, and optional BACnet/MODBUS connectivity—ideal for smart
building automation and process control systems.
Product Features
- Enhanced Range Flexibility: 4 selectable pressure ranges + 4
bidirectional ranges, configurable via dip switches.
- Dual Output Signals: Simultaneous 4–20 mA (2-wire) and 0–5/10 VDC
(3-wire) outputs for controller integration and local testing.
- Digital Connectivity: Optional BACnet or MODBUS protocols support
daisy-chaining (≤32 nodes per segment).
- Square Root Functionality: Converts pressure to linear
velocity/flow for Pitot tube or orifice plate applications.
- Field-Upgradable Display: 5-digit LCD with English/metric unit
selection via pluggable or remote tools.
