4.2 Machine factor
The Machine factor determines the relationship between the measured sensor frequency and the
corresponding speed.
There are two means of determining this value:
4.2.1 Measured
Where the Frequency (f) at the Sensor input and the corresponding speed (n) is known:
4.2.2 Calculated
The relationship between sensor signal frequency (f) and speed (n) at a pole wheel is:
Machine factor is then:
Should a gearbox be present between the pole wheel and drive shaft the formula becomes:
The gearbox ratio is determined as follows:
4.2.3 Other physical parameters
In principle any parameter may be processed as long as it can be translated into a frequency proportional
value. The formulas above may still be applied whereby the required parameter is used in place of speed.
