A method for operating a magnetic-inductive flowmeter includes: detecting the noisy raw measurement signal having a first signal path by a signal sensor with high impedance by the pair of electrodes; passing the detected, noisy raw measurement signal on to a first signal processing device; processing the detected, noisy raw measurement signal by the signal processing device at least into a noise-removed flow measurement signal; outputting the noise-removed flow measurement signal via a working signal interface; detecting the detected, noisy raw measurement signal of the first signal path with a second signal path; and transmitting the detected, noisy raw measurement signal at least indirectly to the first signal processing device and/or a second signal processing device. The first signal processing device and/or the second signal processing device also carry out a frequency analysis of the detected, noisy raw measurement signal. A corresponding magnetic-inductive flowmeter is also disclosed.

Method for operating a magnetic-inductive flowmeter and corresponding magnetic-inductive flowmeter

A spectrometer including at least one light-coupling element, a variable entrance slit, a dispersive element, a detector element and a control and evaluation unit. The object of providing a spectrometer having improved measuring characteristics is achieved in that the variable entrance slit is implemented by a first spatial modulation element including a plurality of pixels, wherein the individual pixels can be arranged independently of one another by the control and evaluation unit, wherein the individual pixels are arranged in order to implement the entrance slit during operation in such a manner that at least part of the light incident from the light-coupling element is passed on to the dispersive element.

Spectrometer and method for analyzing a light sample using a spectrometer

A measuring device for time-resolved measurement of a measurement signal and for temporal separation of at least a first portion of the measurement signal, having a light source for emitting a pulsed excitation signal, at least one detector for receiving the measurement signal, the detector generating a detector signal from the measurement signal, at least one first forming unit for generating a first comparison signal, and at least one evaluation unit, the first comparison signal correlating with the excitation signal. At least one first logic function is provided which links at least the first comparison signal with a signal dependent on the detector signal so that the output of the logic function provides a measure of the intensity of the first portion of the measurement signal or of the detector signal. The output of the first logic function is connected to the at least one evaluation unit.
