X-STREAM Enhanced XEFD Product Data Sheet X-STREAM Enhanced XEFD - Flameproof Gas Analyzer to five component gas analyzer featuring Up NDIR/UV/VIS photometer, paramagnetic and electrochemical O2, thermal conductivity, and moisture sensors Enhanced performance with IntrinzX technology Modern communication capabilities including web-browser accessibility Outstanding reliability with a three-year warranty X-STREAM Enhanced XEFD - Flameproof Gas Analyzer Features The X-STREAM Enhanced flameproof analyzer provides powerful analytical technology in a wall-mountable NEMA 4X/IP66 cast aluminum housing. Worldwide approvals enable operation in Class I, Zone 1, Group IIB+H2 and Class I Division 2 BCD hazardous areas. Modern Communication The X-STREAM Enhanced offers a unique web-browser interface that features: World wide access through the Internet without installation of additional software E-mail notification of alarms and events or with daily reports Complete remote configuration Analytical Flexibility The X-STREAM platform enables the combination of up to five channels of non-dispersive infrared, ultraviolet, visible photometers (NDIR/UV/VIS), thermal conductivity (TCD), trace moisture (tH2O), paramagnetic and electrochemical oxygen (pO2/eO2) detectors. Enhanced Performance With the X-STREAM photometer technology, the analyzer provides a measuring accuracy that allows improving your process while also reducing the total cost of ownership by: Large dynamic ranges Very low temperature dependency Outstanding long-term stability Simplified calibration Three-Year Warranty All important parts and the complete analyzer are run through a variety of test procedures, including long-term stability and temperature behavior. This enables us to provide a three-year warranty for the analyzer, excluding sample-wetted parts and externally connected electronics. X-STREAM Enhanced analyzers provide four status signal relay outputs (according to NAMUR NE 107), MODBUS TCP protocol over Ethernet and RTU over serial (RS232/485) communication. Onboard SD card and USB ports enable storage of: Data, calibration and event logger files Analyzer configuration file A pre-engineered DeltaV module features easy integration into your DeltaV environment via ModbusRTU over serial interface. ProfibusDP is also supported by a ModbusRTU-ProfibusDP gateway. Tools The X-STREAM Enhanced analyzer software provides several tools to make complex process systems easier and avoid additional expenses for third-party equipment: Programmable logic controller (PLC) for control of sample handling and sample lines Calculator for virtual measurements Analog inputs for integrating external measurements into the powerful X-STREAM Enhanced environment
