Thermal conductivity detector, standard gas combinations and measuring ranges (in relation to the mixing gas):

• Infrared sensor, standard gas combinations and measuring ranges (in relation to the proportioning gas):

• Paramagnetic sensor for O₂:
  • smallest measuring range from 0 to 10 vol.%
  • Largest measuring range from 0 to 100 vol.%

Structure of the gas analysis

Universally applicable analysis system with convenient equipment:

• Thermal conductivity detector and/or IR sensor in 19″ 4 U rack-mount housing, alternatively in IP65 field housing. For an extra charge: Installation in wall housing
• Sample gas up to 20 barg
• Status message (min, max, pre-alarm, main alarm) in the display, which are also provided as potential-free contacts on terminals, e.g. for transfer to the control system or for activating a stack light
• Logging of gas pressure and flow rate via 4 configurable analog inputs
• Processing of external signals such as acknowledgement or start of calibration via 12 binary inputs
• 2 additional relay outputs, e.g. for gas mixer switchover or activation of an Ex solenoid valve for fuel gas shut-off
• Data logger, integrated for documenting the gas analysis results. Data recording internally, data can be transferred via RJ45 interface on the outside of the housing, for evaluation e.g. with spreadsheets

• Convenient and intuitive operation via 6″ touchscreen
• Modern graphic color display
• Private label version possible and configurable according to specifications (housing, program interface, logo, language, etc.)
• Password-protected program access
• Extensive self-diagnostic functions with message forwarding
• Development of customer-specific programs and adaptations for individual applications possible
• Integrated PLC control, e.g. for controlling systems, switching gas mixers or switching to backup systems
• Multilingual user interface for gas analysis (currently DE, EN, FR, ES)
• Open interface architecture

Various standard options, individual customizations on request.

Options only in combination with LT gas mixers:

1. Integration in gas mixer (steel housing with lockable glass door)
2. Sample gas conditioning: piped gas paths and gas connections, sample gas pressure control and sample gas flow monitoring, 5-2-way ball valve for switching between sample gas, zero gas and calibration gas for calibration purposes
3. Automatic calibration via additional solenoid valves including control for automatic activation for calibration purposes of sample gas, zero gas and calibration gas

Further options:

1. One analog output for each sample gas component
2. Large 7″ touchscreen for graphical display of the concentration curve with parameterizable time intervals
3. Design of the USB interface on the outside of the housing
4. Evaluation of gas flow measurement (4-20 mA)
5. Customized integration into complete remote monitoring systems (telemetry) via Modbus TCP/IP, Profibus, CANopen, Ethernet, 4-20 mA, web server, FTP host
6. Automatic gas mixer switchover, switchover to backup system
7. Activation of Ex solenoid valve in the gas mixer for fuel gas shut-off
8. Upgrade for outdoor installation
9. Installation in wall housing (400 x 400 x 200 mm)
10. Installation in steel housing with lockable glass door for wall mounting
11. LED stack light with horn for status signaling
12. Other languages
13. Status message in plain text via GSM modem by SMS or e-mail
14. Separate printer, recorder for measurement result documentation
