Series AT2MS ATEX/IECEx Approved Magnesense Differential Pressure Transmitter
Brand: Dwyer Instruments, LLCThe ATEX/IECEx Approved Series AT2MS Magnesense® Differential Pressure Transmitter is an extremely versatile transmitter for monitoring pressure and air velocity in hazardous areas.
This transmitter is loaded with features such as: field selectable English or metric ranges, field upgradeable LCD display, adjustable dampening of output signal and the ability to select a square root output for use with pitot tubes and other similar flow sensors.
Along with these features, the magnetic sensing technology provides exceptional long term performance and enables the Magnesense® transmitter to be the solution for a myriad of pressure and flow applications.
Flame-proof enclosures are available in aluminum and can include a glass window for viewing process on the LCD.
Features- ATEX housing provides all the capabilities and value of the MS2 in a flame & explosion proof enclosure
 - Durable and rugged housing and high-quality components combined provides longservice life and minimized down-time
 - High impact strength and high temperature rated for applications where hazardous environments exist
