Series AT-MS ATEX/IECEx Approved Magnesense® Differential Pressure Transmitter

Series MS in Flame-Proof ATEX/IECEx Enclosure

The Series AT-MS ATEX/IECEx Approved 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. Flameproof enclosures are available in aluminum and can include a glass window for viewing process on the LCD.

Important notes for installation:
• Cables must be fitted through 1/2" NPT cable gland or ATEX/IECEx conduit (not supplied with instrument).
• Make sure after cabling to close tight cover and cable gland, in order to maintain IP66 rating.
• Open cover only after de-energizing instrument.
Attention: Check local safety rules and warnings on unit and manual for a correct use of the instrument in hazardous areas.

Please see Series MS for non-ATEX/IECEx approved.
