    HMI Touchscreen

    Use and Function

    The HMI Touchscreen provides you with the following advantages:

    • Provides Valuable Local Indication: It can be invaluable for field operations to have local indication to gain a better understanding of their process. If this equipment is being used as a Leak Detection device, then this could provide early warning of a small leak or provide rapid indication of a large discrete leak. As well, if this is being used for In-Situ or Extractive Analytical Measurements, then this can ensure the process is within the control envelope. Their are broad types of display options: Graphical and Numerical.
    • Enables Intuitive Local Interface: It is not practical to bring a laptop into a process area and it is not always easy to install software on a corporate computer without permission or a work order from your IT Department. Technicians no longer need to pack a laptop or find away to balance it in the field as the every command or configuration option is available via the HMI Touchscreen.
    • Added Layer of Protection: It is human nature that if we see a button, we’re compelled to push it and the HMI Touchscreen is no different. Since it is common for this equipment to be used in Safety Critical applications, a layer of glass separates the HMI Touchscreen from passers-by to keep those curious fingers away. The HMI Touchscreen is accessible when the Enclosure of the GasFinder3-MC is opened and their is a convenient swinging door to interact with display.
    • Use in Hot and Cold Applications: The Display and Touchscreen functions work throughout the ambient temperature range of -55 to 65°C (-67 to 149°F).

    Local Indication Display Options

    The Field Mounted GasFinder3-MC (Multi-Channel) provides you with the following advantages:

    • Graphical Display: This display option is typically used if trending the concentration variables is of use to operations.
    • Numerical Display (Single Channel): This high contrast display is often the display of choice for leak detection applications as it shows the status of the Hi and Hi-Hi Alarm Relays.
    • Numerical Display (Multi-Channel): At a glance, operations will have a good indication of the concentrations at each path and the customizable naming for each channel will easily help identify which path/channel is being used.

    Premier Performance

    Overview of the Temperature Control

    The Field Mounted GasFinder3-MC (Multi-Channel) provides you with the following advantages:

    • Ready for Hot and Cold Applications: The Field Mountable GasFinder3-MC (Multi-Channel) can be installed throughout the world and handle almost any ambient temperature with an operating temperature range of -55 to 65ºC (-67 to 149°F). The Measurement Head and Active Measurement Path (i.e. Laser Beam) can handle wider temperature ranges than the GasFinder3-MC (Multi-Channel).
    • ±2% of Reading Accuracy: Boreal Laser offers best-in-class performance with ±2% of Reading Accuracy. Particularly for Open Path Gas Detection, all of the other leak detection devices will have ±5% of Full Scale, which is not not very accurate at all…
    • No Diurnal or Seasonal Drift: Laser Based Gas Analysis is sensitive to temperature changes but thanks to the Patented Dual Zone Temperature Control, the GasFinder3-MC can be Field Mounted in a variety of ambient temperature conditions without the need for intervention or degradation of accuracy. There are built-in pressure and temperature sensors within the GasFinder3-MC than can aid in compensating for changing temperatures over diurnal (day/night) and seasonal periods.
    • Optional P+T Analog Inputs: If the environment of Measurement Head differs from that of the GasFinder3-MC (Multi-Channel), then the End-User can input Pressure + Temperature (P+T)  analog variables from external measurement instrumentation to enable Dynamic P+T Compensation.
  • Internal Reference Cell

    Set, Forget, & Detect

    Overview of the Internal Reference Cell(s)

    The Internal Reference Cell(s) within the GasFinder3-MC (Multi-Channel) provides you with the following advantages:

    • Fail Safe Design + SIL2 Suitability: Boreal Laser has focused exclusively on Laser Based Gas Analysis since 1990 and has built an analyzer with +30 years of expertise to provide a Fail Safe instrument that employs detailed diagnostics to help increase the confidence of both technicians and operations. If the GasFinder3-MC (Multi-Channel) is running without fault or status inhibition codes, then the system can be trusted to work as there are no undisclosed failure modes.
    • Essentially Zero Measurement Drift: The Internal Reference Cell ensures that the GasFinder3-MC (Multi-Channel) is still emitting Laser Light at the appropriate wavelength/frequency required to detect that particular target gas. By remaining “Line Locked” or “Line Centered”, we can essentially eliminate Measurement Drift and the requirement for routine intervention and calibration.
    • No Field Calibration: In addition to the GasFinder3-MC (Multi-Channel) interrogating its Internal Reference Cell every minute, the system also compares itself against the permanently stored calibration waveform each and every sample to ensure that the most accurate measurement possible is being made.
    • No Field Intervention: There is no end-user intervention required as all the checks and adjustments from the Internal Reference Cell are done autonomously and automatically. Beyond Optical Alignment of the Measurement Heads, there are no field adjustments to be made with the GasFinder3-MC (Multi-Channel).
