Frauscher wheel sensors, driven by an advanced dual-system architecture, detect the exact location of a wheel using a highly sophisticated algorithm that generates a wheel center pulse and is able to provide accurate measurement information about the speed of a train passing by. The pulse is sent, regardless of travel direction, when an axle or wheel is precisely between two wheel sensor systems. As the wheel passes the middle of the sensor, it triggers track side equipment, such as AEI card readers and vision monitoring, at the precise moments they’re needed.
The RSR110 provides information in the form of load-independent current values. This enables the detection of an axle, direction, speed, axle count, wheel center and wheel diameter to be interpreted from the analogue signal curve. The damping-dependent current signal can be evaluated freely according to the user's own requirements. The sample rate and threshold values for triggering also can be freely selected depending on the specific application.
