Gas Monitors with HART

摘要

MSA's state-of-the-art Permanent Gas Detection System ULTIMA X now features HART [Highway Addressable Remote Transducer] digital protocol, a bi-directional industrial field communication protocol used to communicate between intelligent field instruments and host systems. ULTIMA XL/XT Gas Monitors are worldwide unique as they offer the flexibility to use HART protocol or the very simple and effective local calibration. HART features two simultaneous communication channels: the 4-20mA analogue signal and a digital signal, enabling the user to perform convenient set-up, calibration and diagnostics from any point along the 4-20mA line. With the ULTIMA XL/XT Gas Monitors the user has multiple calibration options: the handheld HART communicator, a controller or laptop which communicates via a dedicated HART Software and local internal LEDs and push-buttons.
