Title: Bridge circuit arrangement
Inventor: KAESTEL WALTER DR
IPC: G01D5/243
Filed: 1984-07-26
Granted: 1986-04-10
Abstract: The bridge circuit arrangement contains a bridge circuit with two fed bridge branches parallel to the input diagonal, at least one of which contains an impedance to be measured. A pulse modulator produces a pulse modulation of the current flowing through one of the two bridge branches, with constant pulse duration but with variable pulse repetition rate. The output diagonal of the bridge is connected to a frequency control circuit which influences the pulse repetition rate of the pulse modulation in such a manner that the mean value of the bridge output voltage is kept at a predetermined constant nominal value. In this manner, the bridge circuit is calibrated by the change in the duty ratio of the pulse-modulated current in one of the two bridge branches. The pulse repetition rate existing in the calibration state is a measure of the value of the impedance to be measured. The current in the other bridge branch can also be provided with a pulse-shaped modulation by a second pulse modulator but this pulse modulation has a constant pulse duration and constant pulse repetition rate, that is to say a constant duty ratio, or an unmodulated current which is supplied by a constant voltage source can flow through the other bridge branch. A signal having the pulse repetition rate, output by the bridge circuit arrangement, represents a measurement value signal suitable for digital signal processing, which ...
