Original BIA Class 1

Pinch Force Measurement System for Bus and Railway Doors


Safety ensured by Pinch Force Measurement

Drive Test’s original BIA Class 1 is an electronic pinch force measuring system for automatic railway doors, light rail and tramway doors and automatic bus doors. Combining rugged construction with precision, the advanced mechanical design delivers exact measurements, even after years of service in an industrial environment.

Vehicles with multiple doors call for fast and easy performance of repetitive measurements. Drive Test has responded to this requirement by developing software which streamlines the measurement process and drastically reduces documentation effort. Measurements made on a complete vehicle can be entered, printed as a table and stored in a database with a minimum of user entries.

The investment in an Original BIA Class 1 System repays itself within a short time.

Our PinchPilot software provides also interfaces like Microsoft® DLL or National Instruments® LabVIEW for remote control in automated environments.
