I have a Hall Effect driveshaft rpm sensor which outputs a voltage pulse every time the magnet on the driveshaft passes by the sensor. I want to add the sensor to my Pro Link cable to log driveshaft rpm and then setup a math parameter to compare engine rpm with driveshaft rpm with trans gearing factored in to calculate slip. The issue I am running into however is that I do not see a way to transform a pulse signal coming in to rpm.
I was thinking if there was a way to continuously add all the pulses to a running total, I could set up a math parameter to calculate as shown below where SumPulse is the running total.
(SumPulse-Shift(ms)SumPulse)/(ms*2pulse/rev) * 100ms/1s * 60s/1min = RPM
Is there a function to register a pulse as a single count and sum it to a running total to input into this math parameter?
If anyone else has any methods they've used to set up a Hall Effect sensor for rpm data logging in HPT I'd love to hear how!
I may just be overthinking this, but haven't been able to find any info online.
