<p>A two body capacitance bridge for accurate capacity measurement which is affected by the presence of the measurement instrument in which a probe (1) is located at the measurement site and includes measuring means, and a measurement instrument (2) is remotely positioned from the probe and interconnected by a transmission channel (3), having a capacitance-to-measurement signal converter (4) connected to a measurement signal transmitter (5) and arranged to transmit a measurement signal and a measurement signal receiver (6) forming part of the measurement instrument (2) and connected to a measurement-signal-to-voltage converter (7) using a standard-component-to-voltage converter (10) arranged to generate a calibrated voltage from a standard component (9) and a detector (8) to measure the voltage differential between the voltage of the measurement-signal-to-voltage converter (7) and the voltage of the standard-component-to-voltage converter (10).</p> |
