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.

NIST CALIBRATION available in Product Configurator.

Questions

Question

We ordered a bunch of MS2-D103-LCD pressure transmitters last year and need to order (20) more this year. It looks like the MS2 is not an option any more and we need to go with a MSX series. We just want to confirm that a MSX-U13-IN-LCD is the same unit as the MS2-D103-LCD and that it is a Duct mount with probe.

Answer

Model number MSX-U13-IN-LCD would be perfect for duct applications to replace the MS2 unit you're currently using.
