StrainDAQ Software Features

  • Supported Systems:
    • Windows XP, Windows 7, Windows 8
    • 64-bit support
    • USB and Ethernet device support
  • Supported sensor types:
    • Strain Gage — convenient default values throughout the setup process reduces the “setup to acquisition” time to an absolute minimum
    • Voltage Transducer — any device, such as a pressure transducer, load cell, full bridge, or current transducer
    • Thermocouple — all common types supported (displayed in user-defined units - °F, °C, °R, K)
  • Supported DAQ drivers:
    • National Instruments NI-DAQmx drivers
    • Measurement Computing drivers
    • Simulated signals — for training without hardware
    • Additional drivers can be configured by request
  • Simple channel setup:
    • Sensor type, input limits, tag-name, calibration type, calibration parameters, scan rate—all selected within one window
    • Setup identical channels easily with the multi-channel copy wizard
    • Tabular view of all setup parameters allows for a convenient review of the entire channel list
  • Four quick calibration methods:
    • Offset only
    • Manual offset and gain entry
    • Two-Point Calibration — a zero and a single shunt calibration
    • Three-Point Calibration — a zero and two shunt calibrations
  • Three methods of data recording:
    • Manual — discrete recording
    • Continuous — data recorded at user-defined time intervals (averaged to “smooth” the data)
    • High Speed — data recorded at a user-defined scan rate with optional oversampling to average data
  • Real-time calculated (virtual) channels available to perform:
    • Mathematical operations (addition, subtraction, multiplication, division, exponentials, polynomials – up to fourth order)
    • Conditional functions (logical If, Then, Else statements)
    • Multi-channel averaging
  • Setups can be easily saved and reused during future tests
  • User-defined display lists that can be toggled to monitor engineering units, raw voltage, zero offset, gain, excitation voltage, and reference excitation voltage
  • Display up to three user-defined plots (time-based or X-Y) in independent windows while simultaneously acquiring data
  • Data files can be exported in a tab-delimited ASCII format for further manipulation
  • Additional optional plugins:
    • Rosette setups:
      • Supported rosette types include single, biaxial (tee), and triaxial (Rectangular and Delta)
      • Allows user to define strain gage rosette parameters (GF, Kt , temperature coefficients) used in “real-time” stress calculations
      • All applicable corrections performed on strain gage channels automatically (bridge nonlinearity, transverse sensitivity, and apparent strain)
      • Routine strain gage reduction (principle stresses, orientation-angle, and equivalent stress)
    • Pipe-bending calculations for axial stress, force, bending stress, bending moment, and axial dogleg — all made in both the 0° and 90° planes
    • Post-processing module (also shipped as a standalone utility known as “StrainDAQ Viewer”) that can create report-quality data plots and stress/strain tables from previously acquired strain gage data
    • Summary file generator and viewer for summarizing long-term data logging into a compressed file. The viewer allows the summary file to be viewed graphically
    • Plot Spectrum — plots the recorded data in the frequency domain for determining frequency components within the data
    • Auto-plot — automatically generates plots and prints them
    • Advanced external timing and triggering options for data collection
