Speed Monitors
Bihl+Wiedemann offers with the speed monitors an effective method for safe processing of signals from sensors and encoders, enabling for example a safety reduced speed for setup operations.
Each speed monitor can be incorporated into the control feedback circuit using adapters and cables already available, without affecting the actual control process.
You find the possibilities of speed monitoring in the application area.
