Hello, Can someone please point me in the right direction ?
I am in the process of changing a Hall sensor that functions as a crankshaft position sensor in my 2CV engine. The existing sensor is about to be sawn in half by a shutter disc and a new set-up is becoming essential.
I now have a good industrial quality Hall sensor, but unfortunately there’s a difference in the output signals between the two sensors. The new sensor outputs 4.40 volts when open, and 0 volts when it detects. The original sensor output only 95 millivolts when open, and 12 millivolts when detecting.
I have tried using resistors to divide the output voltage, but sadly dropping down to 95 and 0 millivolts doesn’t work. The lower value of 12 millivolts seems to be essential as the ECU will not trigger the injectors at 0 volts. I have tried other circuits but without success.
My question to the forum how do I modify the output of the new Hall sensor to obtain the signal values from the original device ? Thanks for any suggestions.
