Abstract
The apparatus is used for connecting in capacitance sensors to electrical measurement systems. The apparatus uses a simplified circuit design that is not affected by temperature or vibration, operates on very low voltage electric power, has a large loading capacity, and stability. The apparatus consists of a low-frequency filter (1) whose input is attached to the output of a XOR logic circuit (2). The non-inverted and inverted inputs of circuit (2) are connected to a reference integration circuit (5) with an arbitrary reference capacitance (7) and a control integration circuit (6) with a time constant proportional to the control capacitance. The appropriate non-inverting and inverting outputs of a symmetric flip-flop (13) are connected to the inputs of these integration circuits.<IMAGE>
