Dwyer Series MS MAGNESENSE Diffirential Pressure Transmitter MS-021
MS-111-LCD Digital Differential Pressure Transducer 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. | Model | Description |
