Hi, jetpr

I thought light or heat resistant alloys were non magnetic ...

How do you do that then ???

I put a ring smal magnet in the from nut of my Turbine and read the nothr and south of the magnetic and that how i read the RPM..

I Use kmz10a Hall Sensor... is a smal circuit for read the RPM...
with pic pro count the pulse ...

GetRPM:

RPM=0
RPMSamp=0
'** RPM **
'60 ms Sample time yields direct RPM readout in 1000's
'Comments start with real RPM of 143,578
Count tachPin, 60 * RPMNumSamps, RPMSamp
RPMSamp = RPMSamp * 10
RPM = RPMSamp / (RPMNumSamps * 10)
IF NOT RPMNoDecimal Then 'Calculate the tenths IF RPMNoDecimal = 0
RPML = RPMSamp // (RPMNumSamps * 10) 'RPML = 0
RPML = RPML / RPMNumSamps 'RPML = 3
EndIF

Return

I hop this help....
