Series MS Magnesense® Differential Pressure Transmitter

Monitors Pressure & Air Velocity

The Series MS Magnesense® Differential Pressure Transmitter is an extremely versatile transmitter for monitoring pressure and air velocity. This compact package is loaded with features such as, field selectable English or metric ranges, field upgradeable LCD display, adjustable dampening of output signal (with optional display) and the ability to select a square root output for use with Pitot tubes and other similar flow sensors.

Along with these features, the patented magnetic sensing technology provides exceptional long term performance and enables the Magnesense® Differential Pressure Transmitter to be the single solution for your pressure and flow applications.

In addition, see Series MSX Magnesense® Differential Pressure Transmitter.

NIST CALIBRATION available in Product Configurator.
