Sensors of series 87350 generally consist of an oscillator, a demodulator and a transformer with moveable core. They are energized by DC voltage. The oscillator uses this DC voltage to generate the carrier frequency, which is needed for the operation of the sensor. Dependent on the position of the core, which is made of ferromagnetic material, voltages are induced by the two secondary coils of the transformer. These voltages will be demodulated, filtered and switched against each other. The result is, if the core is in its centre position, a 0 V output. Each other position of the core causes a DC voltage on the sensor’s output terminal. This output voltage is proportional to the linear deflection of the core.
Input and output terminals of these sensors are galvanically separated from each other, a connection to the sensor’s housing does not exist.
