FADEC Hall sensor troubles...
Hi all,
I've got an interesting problem and I was wondering if anybody has come across this before.
My FACED ECO was slightly singed in a crash (see pictures - sorry for the quality, phone cam). Of course all the wires were burned. The hall sensor was pretty much ripped out too.
I've reconnected the wires and was pleasently surprised to see that it still worked. Better than that, it still had all the data and setup which meant that the electronics stood up to the heat very well. This is one tough unit
.
I've also rebuilt my WREN with a spanking new MK3 compressor and aluminum inlet. It workes fine now except that the rpm reading is not working properly.
Up to 50-60Krpm the reading was ok. After that it kinda went haywire... Anywhere between 100-250krpm! (I'm quite sure I was never near 250!)
I've jakced up the sensor and got better results. It's fine up to 100krpm.
I'm stumped. Is it the inlet? The sensor? The electronics? The magnets? Something else?
Any help will be greatly appreciated.

RE: FADEC Hall sensor troubles...
The magnet is buried in the spinner nut...the aluminum inlet is nonmagnetic aluminum and has no effect. That would leave the sensor, the lead, or the processing circuitry as suspects. If you damaged the Wren enough to need a new compressorand inlet, my guess is that it was the sensor, since it is only millimeters away from the compressor......
Did you get a new tailcone along with the compressor to get that extra 2 lbs (or so) of thrust??

RE: FADEC Hall sensor troubles...
Surely the problem is the magnet, Neodinium magnets loose the magnetic properties if heated, so, if you had enogh temperature to burn the cables, sure that the magnet is de-magnetized. Standard Neodinium allow up to 80ºC, but the one you have (if a wren nut) is OK up to 150ºC.

RE: FADEC Hall sensor troubles...
The magnets are kinda weak... They are barely able to pull a screw driver.
I thought about that but I didn't think that they were subjected to so much heat.
I'll try that anyway. Thanks.
