Title: Improvements in or relating to zero compensation in modulated carrier measuring systems
IPC: G05B1/02
Filed: 1967-10-13
Abstract: 1,212,356.  212,356. Impendance measurement. FRITZ HELLIGE & CO. G.m.b.H. Oct.13, 1967 [Oct. 14, 1966], No. 46700/67. Heading G1U. In an apparatus for measuring a variable of the type where a carrier signal is modulated in accordance with the variable in a sensing system, variations in phase and magnitude of the signal introduced by imbalance of the sensing system itself are compensated. The sensing system A is fed from a carrier frequency generator 17 and the modulated carrier signals therefrom are passed to a signal path including an amplifier 5 and rectifier 13 to provide an output representing the variable being measured. To compensate for imbalance in the sensing system, a signal is fed into the signal path (via transformer 4a) from a compensating circuit D. This includes an auxiliary bridge circuit 33, fed across one diagonal with a second carrier signal, derived from the generator 17, whose frequency and phase are the same as the first carrier. The bridge is adjusted by arrangements controlled to respond to the magnitude and phase of the output from the amplifier 5 only when the sensing system A is non-operative, i.e., no input variable is being applied, to provide an output across the other diagonal which reduces the output from the amplifier J to zero. Arrangements are such that this compensating signal from the bridge output is continuously injected into the signal path during the subsequent operative period of the sensing system when the input variable is applied. The variable may be or control an impedence forming part of a bridge circuit 2 in the sensing system to which the carrier signal is applied at a'e'. Alternatively the variable may be or control a half bridge or differential transformer. The modulated signal is applied via transformer 3a to an amplifier 5, coupled to attenuator 7, amplifier 9, phase controlled rectifier 13, filter 15 and output display arrangements 16. During each period when no input variable is applied to the sensing system any output signal from the amplifier 9 is applied via the switch 25 to the correcting network D. The signal passes via an amplifier 43 to the detectors 28, 27, one providing an output corresponding to the component of the signal in phase with the supply 17, the other providing an output corresponding to the component signal in phase quadrature with the supply. The two detector outputs control motors 30, 29 to drive potentiometers 36, 55 connected across the bridge 33. This bridge continuously provides a signal in accordance with the potentiometer 'settings via a transformer 4a in series with the output signal from the sensing system A to correct any zero error, as detected during the preceding non-operative period thereof.
