1.4.1 Notes on Pole Wheel
The pole wheel must be made of ferromagnetic steel. Non-ferrous material, stainless steel or
plastics do not work.
The grooves / bolts of the pole wheel must be equidistant; otherwise the speed signal will be
unsteady.
The pole wheel should have no damage or burrs; otherwise the speed signal can become
unsteady. If there is any damage, increasing the gap in the air can eliminate a possible fault
(double pulses).
1.4.2 Positioning of Sensor
1.4.2.1 Alignment of Sensor
The sensor must be aligned with the flanks of the profile to be scanned. It is correctly installed if
the two planes at the end of the sensor (which also serve as wrench planes for screwing in)
point in the direction of the profile or perpendicular to the profile edges (for example the tooth
flanks of a gear).
A deviation of up to ± 20 ° is permitted.
