Measurement software Bargrafx™

data acquisitioncalibrationengineering

Bargrafx™ is a LabView® based data acquisition application. When used in conjunction with Capacitec Non Contact Measurement equipment, a powerful tool is formed for precision measurement of small gaps, such as those found in slot die coater applications. Accuracies of better than 10 microinches (0.25 microns) are achievable. Because of the Bargrafx software environment it is possible to use only two channels of amplification in conjunction with several dual sensored gap wands through the use of “virtual channel” architecture and still maintain high accuracies with little loss of overall range. This “virtual instrument” approach saves thousands of dollars in hardware costs. Features National Instruments LabView® based data acquisition application that runs on standard PC using Windows 10® Advanced linearization signal conditioning program Bargrafx™ Equation Editor allows linear or arithmetical équations to be assigned to 8 display bars for a general bargraph user interface Bargrafx équation limits editor Bargrafx Real Time Calibration Module takes the amplifier analog output voltage and scales it into linear engineering units (either English or metric) using polynomial interpolation (to 5th degree) Benefits Ease of set-up and use with industry standard software Accuracies of better than 10 microinches (0.25 microns) are achievable Allows any linearized channel to be added, subtracted, multiplied or divided from any other linearized channel for subsequent arithmetical relations such as sum, gap thickness, tilt, deviation, etc. Allows the assigned bargraph display to reflect upper critical, upper warning, lower critical,
