Digital Contact Tachometer
Posted in Digital Auction on 03/09/2008 10:25 am by adminHow does a non-contact digital tachometer work?
A piece of reflective tape placed on the shaft (but may not be necessary) Tach has a light source and a light sensor on the business end of the tachometer. Pointing to the light / sensor on the axis of rotation of the internal computer detects the reflected light. Computer times the period between pulses of light reflected (the revolution time for individual) and then calculates the revolutions in one minute and displays the result Another LCD write a non-contact sensor uses a Hall effect transistor to detect changes in magnetic fields. This type is less common for a test tach, but is in a dedicated tachometer system. Like a sensor on a distributor breakerless
