ABSTRACT:
A circuit arrangement for converting an inductance value into a specific frequency particularly for producing a pressure-dependent frequency fully compensated against variations in temperature for injection systems in internal combustion engines. The circuit arrangement comprises a comparator, the output of which is connected to a series circuit comprising at least one diode, a coil with variable inductance and a temperature-dependent resistor, all connected to a current supply line with the end of the coil opposite the comparator output coupled back to a first input of the comparator. The potential of the second input of the comparator can be affected by the output value of a voltage divider between the two current supply lines and a regenerative feedback line emanating from the output of the comparator. During the operation of the circuit arrangement, a pulse sequence is obtained, the frequency of which is determined by the inductance.
