Description

Windshield Wiper Pressure Mapping

Utilizing a tactile pressure sensor, the Wiper™ System measures wiper blade to windshield interface force profiles under various testing conditions. The Wiper system measures the force distribution along the entire length of the blade at different positions on the windshield, providing important insights to improve design. It is used as a research and development tool to improve blade and wiper system performance under different conditions such as "lift-off".

Various industry leaders such as Ford, Hyundai, Nissan, Bosch, Toyota, Valeo, and SIAT use the Wiper pressure measurement system to test windshield wiper performance.

Configuration

Wiper™ System Components

  • Evolution™ Handle - (data acquisition electronics) connects to the sensor to gather data, process it, and send it to the PC via USB connection.
  • PB5E equilibration device - the equilibration process compensates for any variation or uneven output across individual sensing elements caused by manufacturing or repeated used of the sensor.
  • Wiper™ Software CD
  • Tactile pressure sensors - model #9901 & #9920

Electronics

Data Acquisition Electronics

Data Acquisition Electronics connect to the sensor to scan the sensing elements and digitally send data to a PC. Electronics are included with a system, but additional equipment may be needed for more complex applications. System breakdown and product specs can be found on the configurations tab.

Electronic Components for System Add-ons

Some system add-ons require hardware to interface with external inputs. A complete list of system add-ons can be found on the add-ons tab.

Add-Ons

System Add-ons

Optional add-on packages are available to provide additional functionality to pressure mapping systems. The features streamline data acquisition, interface with 3rd party devices, or synchronize pressure mapping recordings with video.

Electronic Components for System Add-ons

Some system add-ons require hardware so users and external devices can interface with the pressure mapping system.

Compatible Equilibrators

The equilibration process compensates for any variation or uneven output across individual sensing elements caused by manufacturing or repeated used of the sensor.
