Series MSX Magnesense® Differential Pressure Transmitter

Monitors Differential Pressure, Air Velocity and Volumetric Flow

The Series MSX Magnesense® Differential Pressure Transmitter combines the stability and versatility of the original Series MS2 Magnesense® II transmitter for use in building control applications. The MSX simplifies the ordering process to deliver the desired configuration, which reduces product setup time. Pressure ranges are available in Pa, mm w.c., and in w.c. All pressure ranges can be configured in unidirectional or bidirectional modes, providing a total of 32 ranges. The MSX transmitter can provide a linear pressure output or a linear velocity output with the square root extraction from the transmitter. Additional parameters have been included to expand the square root capability for calculating flow. Dual voltage and milliamp output signals can be used to provide both control and equipment output signal verification.

NIST CALIBRATION available in Product Configurator.

Product Applications

Filter monitoring in air handler units
Building pressure in pharmaceutical/semiconductor clean rooms
Duct static pressure in commercial buildings
Air velocity/flow in VAV systems

Read LCD values easier with rotatable 180° display
Quick and easy wiring via the optional toolless terminal block
Add safety to variety of applications with UL94 V-0 and plenum ratings
