The passive elements in the connection of the typical integrating link at best connected with the operational amplifier with the capacitive feedback are most often used for the integration of the measured signal. The integration time depends in these cases on the size of the resistance, capacity, and quality of the amplifier and therefore they limit it. According to the invention, the connection of the circuit removes these deficiencies. The amplification selection of the potentiometric amplifier causes either the decrease in the size of value of both the elements or increase of the time constant. The time constant is generally expressed by the relation <IMAGE>RC.It is <IMAGE> RC in the case of the connection according to the invention. And where A is the amplification of the potentiometric amplifier.<IMAGE>
