The Research into the Pressure Testing System for Auto Windshield Boneless Elastic Steel Strips

In order to solve the quality problem of the boneless elastic steel strip which was used to scrape the rain on the glass,the solutions for testing the steel strip's pressure was put forward.A special structure pressure sensor based on a solenoid was designed.A master-slave computer architecture of the personal computer and Atmega48 was also adopted which makes the design of the friendly user's interface become possible.The results from the user's application indicate that the pressure testing system achieved the expected effect.
