So your able to measure faster speeds than 1400RPM? Are you just using the magnet they sent with the sensor?
I'm mounted around 1mm or so but I didn't measure like you did. I will try setting with feelers like you did and see if it get any better.
BTW; I had downloaded the Machtach manual (even though I didn't want to buy one of their tachs) to see if they had any info I could use about the sensors. I also did some searching for other info online about the switching frequency of sensors. The original hall effect sensors have a frequency of 320kHz and the new one they sent, the inductive sensor is only 0.5kHz. Somehow I did feel that the frequency was part of the problem. By my thinking, 320kHz is 320,000 pulses per second so It should be more than fast enough, right?
I guess all I can say is the price was right. And as far as 1400 rpm that I dont know. I usually run around 800 rpm and the magnet has not
flown off 'yet'. The magnet is on the circumference of the spindle timimg belt pulley. The instructions are horrible it was all guess work
on my part. My first one blew up using 12vt transformer I left a note with ebay seller and ordered another and then they sent me two
(one for free). This time i used a 9vt battery with a push button switch. Its only needed when changing belts anyways.
