Configurations

Configurations

In order to obtain the pressure data, data acquisition electronics scan the thousands of sensing points within each sensor. The data is instantly relayed to the software on your PC via a USB cable. Our sensors can be scanned at up to 1,600,000 sensing elements/second.

I-Scan offers different options for data acquisition electronics.  To help you choose the best fit for your application, explore the configurations below or download the I-Scan Product Selection Guide for more detailed information and specifications on the various system options, features, and configurations.

Software

Software

Standard I-Scan software window displaying the pressure distribution between a brake pad and rotor.Standard I-Scan software window displaying the pressure distribution between a brake pad and rotor.

I-Scan provides the tools for more comprehensive and higher quality analysis than ordinary pressure sensing technologies.

The software displays the pressure distribution data, in multiple formats, for superior analysis. Data and imagery of the pressure distribution are shown in real-time with the ability to record, play back, and save FSX movies. The user has the option to create and customize graphs from the corresponding movie data or export as an ASCII file for use with other programs.

Key Features

  • Real-time display of pressure sensor data in 2D & 3D
  • Graphing & data analysis (pressure, force, & area)
  • View data as an integrated Microsoft Excel table
  • View and compare multiple test results simultaneously
  • Display peak pressures & center of force
  • Export data to ASCII or AVI files

Graphic & Data Analysis

2D pressure output with Force vs Time graph2D pressure output with Force vs Time graph

Force vs. time graph – the cursor at 3 seconds correlates to the pressure output on the left. Users can click any point in time along the x-axis to view the resulting pressure output image.

 

Data available from each frame:

  • Total Force
  • Center of Force location
  • Peak Pressure
  • Pressure distribution (i.e. force on each sensing element)

Sensor MAPs

Each sensor requires its own unique MAP driver file for the software to function properly. By utilizing sensor MAPs, the software is able to provide an accurate depiction of each unique sensor layout. The sensor MAP controls the shape of the pressure image window in the software, which corresponds to the shape and dimensions of the sensing area on the sensor.


Visualization

Realistic Data Representation

  • Optimized 2D display algorithms in the software interpolate sensor data to smooth pressure map display; giving a more realistic representation of the object being measured
  • Select among three Interpolation views:

    • Level 1 (1 x 1 No Interpolation)

    • Level 3 (3 x 3 Interpolation)

    • Level 5 (5 x 5 Interpolation)

Property Table

I-Scan includes the new Property Table feature.  Property Table makes it easier to access sensor data, by allowing you to view data as an integrated Microsoft Excel table*.  Data can be viewed and graphed within a single Excel spreadsheet from within the Tekscan software.  Formulas can be added to the table to provide application specific values.  Customize Excel calculations, sort, and format from directly inside the Tekscan software.
