I-Scan® Handheld Pressure Measurement System

Software Features of I-Scan
Handheld Basic:
  • 2-D display of real-time sensor output
  • Displays snapshot of pressure distribution
  • Saves snapshot with either automatic file naming or user entered file name
  • Screen image saved as *.bmp for use in other programs
  • Eight adjustable sensitivity levels - to raise or lower the pressure range of the sensor
  • Text comments are saved with data files to document experimental conditions
  • Show pressure - average digital output on sensor, and count of sensels at each pressure level
  • Eight bit, 256 level pressure resolution
  • Adjustable color key, averaging, mirroring and rotating sensor image to provide desired view
  • And much, much more!

Additional Features in Handheld Enhanced:

  • Stand-alone calibration (linear or power law)
  • Equilibration improves uniformity of sensor response
  • Tare offsets initial base load on sensor from dynamic measured load
  • Show loaded contact area & total force on sensor
  • Center of force on display

 

New Handheld System

When small system size and portability are important in collecting pressure data, I-Scan Handheld is ideal for capturing contact pressure distribution. One of the many ultra-thin Tekscan array sensors is inserted between two surfaces. Scanning and interface electronics in the handle read the sensor and send data through a USB connection to the Pocket PC (PDA). A vivid, real-time, 2-D image, with color indicating different pressure levels, is displayed. Snapshot recording is controlled either by touch screen or switches on the handle.

The small size, weight, and battery power of I-Scan Handheld are convenient for field use.

Applications include:
  • Adjusting nip rollers in converting machines
  • Sealing jaws and packaging machines
  • Adjusting automotive door and window seal pressures
  • And many, many more.
Two levels of software are available for I-Scan Handheld. Basic software is a subset feature of classic I-Scan (PC based), providing relative measurements. The Basic software is also intended for organizations that have classic I-Scan operating on a PC and desire additional systems for field use or more portability. With classic I-Scan operating on a PC with an Evolution handle, calibration and equilibration data can be downloaded to a Basic Handheld system on a PDA. After data is captured in the field and stored on the PDA, it can be displayed using classic I-Scan on the PC for more thorough analysis. The Enhanced software adds calibration and equilibration capability and other I-Scan features making I-Scan Handheld Enhanced a powerful stand-alone product.
