Dwyer MSX Pro Magnesense Differential Pressure Transmitter
Product Introduction
The Dwyer MSX Pro Magnesense Differential Pressure Transmitter is a
professional-grade device designed for precise monitoring of
differential pressure, air velocity, and volumetric flow in
critical building applications. Engineered to meet stringent
industry standards, it combines exceptional stability with
versatile functionality, leveraging innovative global design
principles. The transmitter offers 32 configurable pressure ranges
in Pa, mm w.c., and in w.c., supporting both unidirectional and
bidirectional modes. With dual voltage/milliamp outputs, square
root extraction for velocity/flow calculations, and NIST
calibration options, the MSX Pro simplifies setup while delivering
reliable performance in high-stakes environments.
