•
Measurement direction
Three measurement directions can be selected: Axial, Radial or Tangential.
If Axial is selected, the sensor measures along the machine’s axis.
Selecting Radial switches to measuring perpendicular to the machine’s axis.
Tangential means measuring the axis under a certain angle.
•
Speed sensing surface
Four options for the speed sensing surface are available: Involuted (typical gear wheel
shape), Squared (squared teeth on speed wheel), Pole band (toothed band around machine
shaft) or Rounded (drilled holes which are typically located axially).
•
Speed wheel module
Enter factor of speed wheel diameter divided by the number of teeth (for example, a diameter
of 200 mm and 100 teeth results in a speed wheel module value of 2).
