DESCRIPTIONAPPLICATIONS

• High performance building applications for critical

environments

• Filter monitoring in air handler units

• Building pressure in pharmaceutical/semiconductor

clean rooms

• Duct static pressure in commercial and specialized

buildings

• Air velocity/ow in VAV systems

The Series MSX Pro Magnesense® Differential Pressure Transmitter is the professional differential pressure transmitter meeting stringent industry standards with innovative global product design. The device has exceptional stability for use in critical building performance applications with the popular versatility of our original Series MS2 Magnesense® II transmitter.

The MSX Pro simplies the ordering process to deliver the desired conguration, which reduces product setup time. Pressure ranges of Pa, mm w.c., and in w.c. are available per device. All pressure ranges can be congured in unidirectional or bidirectional modes providing a total of

32 ranges. The MSX Pro 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 to calculate ow. Dual voltage and milliamp output signals can be used to provide control and equipment output signal verication.
