The microcontroller in the photo-tachometer then does some simple maths – twenty pulses in one second, multiplied by 60 seconds – and we get a rotational speed of 1200 revolutions per minute on the display. In one second, the white spot will pass the beam twenty times, triggering our light sensor as it goes by. Let’s assume the photo-tachometer counts the number of pulses it sees in a unit time of one second to make its measurements. We aim the photo-tachometer’s beam at the white spot we’ve marked on the motor’s shaft. By counting the number of times the light sensor is triggered in a given time, it’s possible to determine the rotational speed of the machinery under test.įor example, let’s say we have a motor spinning at 1200 revolutions per minute. Each time the reflective spot passes the beam of the photo-tachometer, some light is reflected back towards the device, where it is picked up by a light sensor. Then, aim the beam of light from the photo-tachometer at the mark on the spinning shaft. An easy way to do this would be to create a white spot with a paint marker on an otherwise black or dull-metal shaft. You must also ensure the rest of the rotating surface is comparatively non-reflective. To use the photo tachometer, you start by creating a reflective mark on the rotating surface you wish to measure. Note the marker on the chuck of the drill, which reflects light back to the phototachometer. This beam of light is capable of bouncing off of reflective objects. The device contains a light source – typically a laser, which can create a focused, coherent beam of light. The basic principle of operation of a photo-tachometer is quite simple. And the most useful tachometer is the non-contact photo-tachometer. Sometimes, it’s important to know precisely how fast they are spinning! When you’ve got the need to know angular speed, you need a device to measure it.
