Windshield Wiper Pressure Mapping

Utilising 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.”

Key Features:

• Graphic and analysis capabilities
• Map force distribution along wiper blade
• Access real-time or recorded data
• Dynamic measurement for “lift-off” testing
• Collects and consolidates static measurements at different angles to capture full wiper cycle

Wiper System Components

• Tactile pressure sensor – model 9920
• 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

Wiper Blade Sensor

• Minimally intrusive, flexible, thin-film sensor
• Specifically designed for use with wiper blades
• Durable and reusable
• Thin & incompressible – dimensional stability is key for repeatable measurements
