Dwyer advises its customers to obtain the latest version of the relevant information to verify, before placing any orders, that the information being relied upon is current. 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 simplifies the ordering process to deliver the desired configuration, 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 configured 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 flow. Dual voltage and milliamp output signals can be used to provide control and equipment output signal verification. • Easily access the unit’s wiring via the flip-lid housing • Eliminates accidental damage to the unit during installation with the products innovative design shielding the electronics underneath the PCB • Added security and protection from the tamper-resistant cover • Protection from liquids and moisture near the cable egress point with the included liquid tight cable gland fitting • Reduce installation time with quick and easy wiring via the included a toolless terminal block • Add safety to variety of applications that need to meet municipal and building code standards with UL94 V-0 and plenum ratings • 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/flow in VAV systems BENEFITS/FEATURES DESCRIPTIONAPPLICATIONS SERIES MSX PRO | MAGNESENSE ® DIFFERENTIAL PRESSURE TRANSMITTER HOW TO ORDER Use the bold characters from the chart below to construct a product code.
