Linear output sensor concepts
Linear output Hall effect sensors can
provide mechanical and electrical
designers with significant position and
current sensing capabilities. These
sensors combine a Hall effect integrated
circuit chip with the state-of-the-art thick
film technology. Linear output sensors
can be used in a wide variety of sensor
applications. Position sensing of cams,
shafts, floats and levers, temperature
sensing, current sensing, and circuit fault
detection are just a few of the many
possible applications.

Figure 7-5 Microprocessor linearization
The output voltage of a linear sensor as a
function of magnetic field (from a permanent
magnet or an electromagnet) is linear, while the
output voltage as a function of distance may be
quite non-linear. Several methods of
converting the voltage output of a linear sensor
to one which compensates for the non-linearity
of the magnetics as a function of distance are
possible. One method of obtaining a linear
relationship between distance and gauss is shown in
Figure 7-5. This involves converting the analog output to
digital form. The digital data is fed to a microprocessor
which linearizes the output through a ROM look-up table,
or transfer function computation techniques.
