Abstract

A permanent magnet (18) interacts with a Hall probe (19). The distance separating the permanent magnet (18) from the Hall probe (19) can be modified by means of an element (15) to which pressure (p) is applied, whereby a variable Hall voltage is produced. In order to linearise the dependence between the pressure and the electric signal, a sine-function network (23) is connected behind the Hall probe (19). <IMAGE>
