Rotational speed sensor
KMI15/4
FUNCTIONAL DESCRIPTION
The KMI15/4 sensor is sensitive to the motion of ferrous
gear wheels or reference marks. The functional principle is
shown in Fig.3. Due to the effect of flux bending, the
different directions of magnetic field lines in the
magnetoresistive sensor element will cause an electrical
signal. Because of the chosen sensor orientation and the
direction of ferrite magnetization, the KMI15/4 is sensitive
to movement in the ‘y’ direction in front of the sensor only
(see Fig.2).
The magnetoresistive sensor element signal is amplified,
temperaturecompensatedandpassedtoaSchmitt-trigger
in the conditioning integrated circuit (Figs 4 and 5).
The digital output signal level (see Fig.6) is at a fixed level
independent of the sensing distance. A (2-wire) output
current enables safe sensor signal transport to the
detecting circuit (see Fig.7). The integrated circuit housing
is separated from the sensor element housing to optimize
the sensor behaviour at high temperatures.
The strength of the magnetic field caused by the
Ferroxdure 100 magnet in the different sensor directions,
measured at the centre of the magnetoresistive bridge, is
typically: H
x
= 7 kA/m (auxiliary field) and H
z
= 17 kA/m
(perpendicular to the sensor surface). H
y
is zero due to the
trimming process.
