2. Linear distance measurement
To convert small distances into a proportional electric signal, a small soft iron part of
definite width (e.g. b = 1.8 mm) is moved over the face of the sensor.
Proportional signals for distances up to 1.5 mm can be obtained in this way. The
sinusoidal output signal gives a voltage proportional to distance in the zero crossover
region (see Fig. 3).
