The ATEX 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 selec 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 ATEX enclosures are available in aluminum and can include a glass window for viewing process on the LCD.
? Cables must be fitted through 1/2" NPT cable gland or ATEX conduit (not supplied with instrument).
? Make sure after cabling to close tight cover and cable gland, in order to keep IP66 rating (IP65 with option OPV, overpressure relief valve).
? Open cover only after de-energizing instrument.
