What is IQ™?
Basically IQ™ is a Speed Sensor...
... but also a lot more than a Speed Sensor:
 Overspeed protection switch
 Digital to analogue converter
 Signal analyse
 Signal with frequency division
 Sense of rotation (CW, CCW)
 and, and, and ....

Engine Diagnostics
 Diesel engines do not run totally round.
There are masses in linear movement and
there are compression and burning cycles
which accelerate and decelerate the
system.
 These effects cause variations in the
The speed signal contains information
about the compression, the burning cycle
and the internal friction; or in other words
the basis for an engine diagnostics.
