Abstract: A measuring device has a transmitter side that is connected to a receiver side over an optical transmission link. The transmitter side receives an input measurement signal from a transducer and applies the input signal to an adder that also receives a feedback signal from the receiver side. The adder generates a comparison signal that corresponds to the difference between the input signal and the feedback signal. The comparison signal is applied to a regulator on the receiver side. The regulator generates the feedback signal and an output signal having a magnitude corresponding to the magnitude of the input signal. Amplification of the feedback signal on the receiver side is controlled by time division or frequency division calibration signals, so that the total amplification of the feedback signal between the adder and the regulator is held constant.
