portable pressure measurement

Handheld pressure measurement system for collecting tactile pressure data.

<em>I-Scan</em><sup>®</sup> Handheld System

Portable Pressure Mapping

I-Scan Handheld is a lightweight, PDA system that allows for quick interface pressure measurements on site or on the field and assembly line. I-Scan Handheld can be used as an individual system or can be added to the standard I-Scan pressure mapping system for increased flexibility.

Key I-Scan Handheld Features:

Lightweight and portable
Simple, easy to use software
Battery powered from PDA, no external power needed
Data collection and presentation is performed on the PDA
Durable and reusable pressure sensors
Scanning rate of up to 75 Hz
Real-time refresh rate of 10 Hz
Snapshots of pressure distribution

A Tekscan system consists of scanning electronics, software, and patented thin-film, tactile pressure sensors. To learn more about our scanning electronics and sensor performance specifications, please visit our Sensor Technology page. Our qualified engineers will help you select the optimal system configuration to meet your application requirements.

I-Scan Handheld Components:

(1) Evolution^® Handle - Every Tekscan system uses specially designed scanning electronics called Handles or Cuffs. The electronics connect to the sensor, gather the data from the sensor, and then process and send this data to your computer via USB connection.

I-Scan Handheld Software Options

Basic software is a subset of classic I-Scan (PC based), providing relative measurements. 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 I-Scan Handheld system on the SoMo PDA. After pressure 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.

Key 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 (histogram)
Adjustable color key, averaging, mirroring and rotating sensor image to provide desired view
And much, much more!

I-Scan Enhanced software adds calibration and equilibration capability and other I-Scan features making I-Scan Handheld Enhanced a powerful stand-alone product.

Additional Features in I-Scan Handheld Enhanced:

Single-point calibration (linear)
Two-point calibration (power law)
Sensor Equilibration (normalization) 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

The software is available in several languages including Spanish, French and German. View software languages available.
