The GEL 2475FD CombiCODER combines the already familiar speed signals
based on the tried and tested interference-resistant magnetic
scanning with state-of-the-art MEMS technology. The two
systems discussed use supply voltages that are independent of
one another and entirely without feedback.
The flat spot detector accurately identifies flat spots and welds
on the wheel and indicates the severity in clear, defined phases.
This means that workshop visits can be planned early and efficiently
without causing disruption to operational processes.
If several flat spot detectors are used, rail joints can also be
detected.
Temperature measurement is using an integrated NTC Thermistor.
Thanks to the compatible sensor housing, existing speed sensors
can be replaced with the GEL 2475FD with minimal effort.
The flat spot detector signal output is an analog PWM signal
with HTL output
