RPM sensor SkyView sytem

[Cherokee260]

Is there a sensor for RPM reads for 1966 Cherokee six 260 lyconing 0-540? SkyView engine monitor system.Thank you

It's the same as any other six-cylinder: 1.5 times engine rpm.

Thank you Kellym , but I was wondering if there is a sensor that can read the RPM’s since the engine monitor system for the SkyView system doesn’t come with one.

The default setup for the Dynon connects the RPM input simply to the magneto P-leads so there is no 'real sensor', but for different engine types any pulse generating sensor (or engine controller, that generates one or more pulses per revolution) may be used, and these can be connected to the low-voltage RPM inputs. Advantage of the P-lead connection is that the Dynon disply can see the difference between left and right and hence detect the drop in RPM during P-lead testing

For experimental aircraft, I used a Hall Sensor, with a simple circuit to protect the sensor from voltage spikes and limit the current. Two small magnets mounted to my ring gear at 180 degrees apart to maintain balance completes the setup. When powered by the main bus, it produces two pulses / rev between 14.2 - 0 volts and 3 mA max. I attached this to the high voltage RPM input which works flawlessly.

My Lycoming uses a sensor that screws into the side of the slick magneto. I would guess this would be more likely to be approved for a certified aircraft.

The certified Dynon installation uses the P-Leads at the ignition key switch, with some resistors.

The sensor that screws into the magneto are usually part of a kit from JPI or Electronics International, approved under their STC's
