Thanks for the input, I've done my best to try and make the sensors as symmetric as possible to each other and to the magnet on the flywheel. I can double check to make sure the mounts have not moved, but they were fairly secure and rigid. The 10nF capacitor should be placed between the...

Currently I'm using differential signals for the DAQ system but not into the ignition system. The ignition coil is ~8inches from the hall sensors although theres a few metallic components between the two (covers and whatnot). Disconnecting the coil and checking the signals will be among the...

Hi VE1BLL, I'm currently using twisted (shielded) pairs running from the hall sensor to the ignition system(w/ internal processor) and to the DAQ system to reduce noise. With this talk of twisted pair shielding I remembered that the actual ignition wires are not in twisted pairs or shielded...

Thanks for the quick response, The hall sensor is attached to an electronic ignition system(EIS) that takes ~10mA (open collector input pretty sure) and a National Instruments DAQ system that requires minimal amperage if any. It's interesting you say an inductive kick-back, the ignition system...

Hello all, I am working with a "Hamlin 55100" Hall effect sensor (actually two of them with overlapping output signals 5V->~0V->5V), whenever I trigger the two hall sensors with a magnet I get a really ugly pulse (as seen in photo). At the end of the pulse there is a transient response that...
