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.
