Sensor Sense: Measuring rpms Feb. 9, 2006 The monitoring of rotation can involve such sensor types as proximity, photoelectric, resolvers, encoders, and tachometer generators.
Of course the problem is that the sensor raw data may be as low as 400 counts per inch, and when moving slowly, let’s say an inch a minute, you only get a blip up every 150 milliseconds.
OPT short-range diffuse distance sensors utilize high-resolution CMOS line array technology, eliminating material, color and brightness-related measurement differences. Analog and switch output models ...
