FM 205

Pinch Force Measurement System for Powered Window Lifters

Safety ensured by Pinch Force Measurement

The FM 205 is an electronic force measuring system for powered window lifters. Typical use includes R+D and production testing in the automotive industry. The FM 205 is characterized by its ease of use for repetitive measurements. According to the requirements of different standards a large variety of spring stiffnesses is available. It is also increasingly used by technical safety agencies. Combining rugged construction with precision, the advanced mechanical design delivers exact measurements, even after years of service in an industrial environment. Fast and easy performance of repetitive measurements is an important aspect of standard test scenarios.

Drive Test has responded to this requirement by developing software which streamlines the measurement process and drastically reduces documentation effort. Measurements can be downloaded to a PC, analysed, exported and documented with a minimum of user interactions. Our PinchPilot software provides also interface like Microsoft® DLL or National Instruments® LabVIEW for remote control in automated environments.
