    LT GasAnalyzer

    Highly performing gas analyzer for measuring the concentration of technical gases based on a thermal conductivity sensor, an infrared sensor a para magnetic sensor or combinations of these sensors. Sensors are precise, robust and have a low cross-sensitivity.

    Our Solution

    Modular system including numerous built-in functions, and is ready for upgrade with multiple options:
    • Extractive online measurement of the concentration of flammable or non-flammable gas components in gas mixtures
    • Response time (T90 time): < 20 seconds
    • Fully automatic operation, with integrated PCS, expandable to be used for a measurement-guided control of devices, such as gas mixers.
    • Low drift sensors w. low cross-sensitivity, for high long-term stability
    • Optionally with automatic calibration, to ensure a constant gas mix quality
    • Reliable, highly sensitive and precise
    • Suitable for installation outside ex-zones
    • At request, tailored configurations to suit individual specifications

    Design

    Versatile analysis system comfortable furnished

    Convenient Features

    • Sensor in 19″ 4 height units rack mount chassis
    • Integrated PLC
    • Admits sample gas with a pressure up to 20 bar(g)
    • Displays status messages (min, max, pre-alarm, main-alarm), which are as well provided as potential free contacts on clamps, e.g. to transfer to the control system or to control a lamp stack.
    • Logging of gas pressure and gas flow with 4 configurable analogue inputs
    • Processing of external signals such as acknowledgment or start of calibration over
      12 binary inputs.
    • 2 additional relay outputs, e.g. for gas mixer switchover or control of an solenoid valve for switching-off fuel gas
    • Data recording to SD card or USB memory, e.g. for evaluation with Excel

    Operation and Communication

    • At request customized programs and adjustments for individual applications
    • Open interface architecture

    Options

    Several standard options. Individual configurations available upon request.

    Options only in combination with LT gas mixers:

    1. Integration into gas mixer (steel with lockable glassed door)
    2. Gas sampling: Gas pipes and gas connections, monitoring of gas pressure and flow, 5-2-way valve for switching for calibration purposes between measured gas, zero gas and calibration gas
    3. Automatic calibration with additional solenoid valves incl. control for automatic
      switching between measured gas, zero gas and calibration gas

    Further options:

    1. One analogue output for each sample gas component
    2. Larger 7“ touch screen for graphic display of concentration trend with configurable time intervals
    3. USB interface on case front
    4. Evaluation of gas flow measurement (4-20 mA)
    5. Customized integration into plant remote monitoring systems (telemetry) via Modbus TCP / IP, Profibus, CANopen, Ethernet, 4-20 mA, Web Server, FTP Host
    6. Automatic switch-over between gas mixers , or to backup system
    7. Control of an solenoid valve for shutting-off fuel gas flow
    8. Upgrade for outdoor erection
