Table 8 Summary of advantages and disadvantages of typical measurement set-ups
Measurement examples using Philips’ sensors
For measurement, Philips’ KMZ10A/B/C and KMZ51
sensor types can be used. The KMZ10A/B/C have to be
stabilized with auxiliary magnets, for example as in the
KM110B/2. KMZ51 sensors contain internal conductors
(‘coils’) to compensate for offset and temperature drift and
do not need an auxiliary magnet, allowing for simple
circuitry with reduced need for adjustments. As these
sensors do not measure fields above about 230 A/m
(approx. ten times the earth’s magnetic field), they must be
used in a measurement set-up that reduces the effects of
interference fields, as described above.
The following examples demonstrate Philips’
magnetoresistive sensors being used in real-life situations.
AC
SENSORS
Two KM110B/2 sensors, placed as outlined above, are
in-phase for current measurement and antiphase for
external field compensation, eliminating the effects from
stray fields and improving sensitivity (see figs 47 and 48).
