Interest in sensors for contactless measurement of high
currents has been steadily increasing and to help
customers apply this technology, Philips has prepared a
module for testing, based on our KM110B/2
magnetoresistive sensor (equipped with a stabilization
magnet). It consists of the KM110B/2 sensor, conditioning
electronics and a U-core.
The wire carrying the current to be measured should be
fed through the U-core, but a short distance should be
maintained between the wire and the sensor. Figure 53
shows the influence of wire position on sensitivity. If wires
are thin, a spacer above the sensor can prevent errors in
the measurement. Cables or conductors with large
diameters are less sensitive to this effect. Ring cores with
an air gap are generally less sensitive to wire position but
are more difficult to obtain and mount, so a U-core was
used for these test modules.

Figure 54 shows the conditioning electronics for this
set-up. In principle, it is similar to the basic conditioning
circuit in the ‘General introduction’ (see Fig.11), although it
has been optimized for this particular application and has
the following characteristics:
Supply voltage V
Current range: 16 A
Frequency range: 0 to 1000 Hz
Temperature range: 40 to +80 C
Sensitivity: 135 mV/A
Sensitivity temperature drift
(temperature range 20/+85 C): < 0.8%
Quiescent output voltage (I = 0 A): 2.5 V
Quiescent output voltage temperature
drift (temperature range 20/+85 C): < 25 mV
Equivalent current drift: < 0.2 A.
The typical response of this sensor and circuit set-up is
shown in Fig.55 and shows the excellent linearity, even for
large currents.
