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).
