Estimating the term…
The invention concerns a sensor arrangement having at least one condition parameter sensor, one sensor connection structure for the connection of the at least one condition parameter sensor to a structural construction element as well as with one of the signal processing devices which are coupled to the at least one condition parameter sensor, which includes a frequency elimination filter for an averaging of the signal of the at least one condition parameter sensor over the cycle duration of the first natural frequency of the sensor arrangement. This creates the possibility of creating a notch filter with a notch frequency, which corresponds to the first natural frequency of the acceleration sensor arrangement and exhibits a high filter quality. The notch frequency and the whole number multiples are thereby fully eliminated and disturbances due to the natural frequencies of the sensor arrangement are avoided.
A sensor arrangement comprising at least one condition parameter sensor, one sensor connection structure for connection of the at least one condition parameter sensor to a structural construction element and at least one signal processing device which are coupled with the at least one condition parameter sensor, that includes a filter unit for signals of the at least one condition parameter sensor, whereby the filter unit is set up as a frequency elimination filter for averaging of the signals of the at least one condition parameter sensor over a cycle duration of the first natural frequency of the sensor arrangement.
A process for digital signal filtration of a signal from at least one condition parameter sensor in a sensor arrangement having one sensor connection structure for the attachment of the at least one condition parameter sensor to a structural construction element, by means of a filter unit, whereby an averaging of the signal of the at least one condition parameter sensor is undertaken using a cycle duration of the first natural frequency of the sensor arrangement.
