Data Acquisition Electronics and Sensor to PC Interface

Every Tekscan Industrial system, including Wiper, uses a specially designed sensor interface electronic called a "handle". The handle connects to the sensor, gathers the data from the sensor, and then processes and sends this data to your computer. The handle connects to the PC via a USB cable. Each interface product embodies sophisticated microprocessor based circuitry to control scanning sequence and frequency, adjust sensitivity, and optimize the performance of our sensors.

Sensor Description
Model #9901, Model #9920

Spatial Resolution: 4.0 sensels/linear in (1.57 sensels/linear cm)
Technology: Resistive
Calibration: With application of controlled device
Sampling Rate: 10 Hz
Pressure Range: 0 - 10 PSI
Sensor Thinness: 0.004 in (0.1 mm)
 Sensor Model #9901
96 Sensing Elements, 24 in x .38 in (609.6 x 9.65 mm)

Sensor Model #9920
128 Sensing Elements, 32 in x 0.77 in (812.8 x 19.49 mm)

The Wiper system comes standard with:

Equilibration/Calibration Devices - Pneumatic devices apply a uniform pressure to the active area of a sensor to normalize output of each sensing element. The system electronically compensates for variation in individual sensing elements.

Related Products & Options

Tekscan systems provide the flexibility of adding on capabilities as your needs evolve to enhance data analysis and interpretation. Please ask us about any of the add-on options to the I-Scan system listed below:

Wireless Capability - Enables a wireless connection between your sensor/handle and your PC allowing for ultimate flexibility in data acquisition.

Video Synchronization™ - Video sequences can be recorded and synchronized with your pressure data and visualized in Tekscan software, enhancing the utility of collected data.

ASR (Automatic Sequential Recording) - Allows the system to automatically start a new recording when the current one is complete, without the need to manually open new real-time windows and start new recordings.

API 2 (Application Program Interface) - API 2 software enables a user, with programming knowledge, to write programs that directly access Real-Time sensor data buffers. The user interface is preserved with API 2.

Advanced Analysis (Polygon/Blob/Tracking Box) - This software package includes three options for more thorough analysis, such as allowing you to add a custom shaped box or window to a Real-Time window, ability to study loaded sensels in a particular area, and the ability to add a box to a movie or Real-Time window that will follow the loaded sensels in a given area.

Tab Extender - Increase the distance between your sensor and the Tekscan sensor scanning handle (electronics) with Tekscan’s reusable Tab Extender.

Save MatLab™ - Save Tekscan movie data (*.fsx file format) into a MATLAB MAT-File (*.mat file format) for greater flexibility in analysis.
