PRESETTABLE TRANSDUCER FOR ELECTRICAL QUANTITIES

摘要

A presettable transducer for electrical quantities, comprising a sensor and a conditioning circuit, of the type in which the sensor is connected to a primary electrical quantity source and is arranged to provide as output an electrical quantity proportional to the derivative of said primary electrical quantity, the conditioning circuit being connected to the sensor output and being disposed to provide at its output a primary electrical quantity by integrating the sensor output quantity, characterised in that the conditioning circuit comprises passive components of resistive type and reactive type, these latter with a loss factor which at the frequency concerned is of the order of 10-4.
