FM 208

Pinch Force Measurement System for Sunroofs, Powered Window Lifters and Tailgates

Safety ensured by Pinch Force Measurement

The FM 208 is an electronic force measuring system for sunroofs, powered window lifters and tailgates. Typical use includes R+D and production testing in the automotive industry. With the low spring stiffness, the FM208 is designed to test soft parts pinched in a closing system.

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.

We have 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 interfaces like Microsoft® DLL or National Instruments® LabVIEW for remote control in automated environments.
