Series MS2 Magnesense® II Differential Pressure Transmitter

Monitors Pressure, Air Velocity and Air Flow, BACnet/Modbus® Communications

The Series MS2 Magnesense® II Differential Pressure Transmitter combines stable piezo sensing technology with the additional features to reduce installation time and simplify ordering. Like the original Series MS, the second generation transmitter can be used as a linear pressure output or a linear velocity output with the square root extraction done in the transmitter. Additional parameters have been included on the MS2 to expand the square root capability to include flow measurements.

NIST CALIBRATION available in Product Configurator.

Product Applications

Duct Static Pressure in Commercial Buildings
Filter Monitoring in Air Handler Units
Building Pressure in Pharmaceutical-Semi-Conductor Clean Rooms
Air Velocity/Flow in VAV Systems
