Fast acquisition and recording of analog signals with ibaPADU-4-AI-U
Sampling rate for the first time freely adjustable to up to 100
ksamples/s
iba AG enters new speed classes in the field of sampling rates for industrial
analog-digital converters. At the „Sensor+Test 2013“ in Nuremberg, the German
company presents its new ibaPADU-4-AI-U compact device, that offers a
sampling rate which can be adjusted for the first time to up to 100 ksamples/s.
„The ibaPADU-4-AI-U is a further development of the successful PADU
technology and rounds off our product range of transducers to the upper end“,
Dr. Ulrich Lettau - CEO of ibaAG - explains. The measurement system with four
electrically isolated inputs has been designed for acquiring and recording fast
analog signals. The system can be used for special applications in test
benches, in Condition Monitoring, for sound- and vibration measurement as
well as for power quality measurements.
When doing test bench measurements for example, highly dynamic processes with
sound frequencies up to the near ultrasonic range are being recorded. For meeting
the measurement relevant requirements, ibaPADU-4-AI-U offers an integrated signal
pre-processing with a sampling rate of 400 kHz. The signal that is sampled on the
analog input with 400 kHz, is internally processed with a digital filter which can be
freely configured up to the 14th order. This method – the so-called Oversampling –
ensures that a steep-edge and high quality filtering of the signal to be acquired can be
done. Hence, the signal can be digitalized with only low distortions. Selectable analog
and digital antialiasing filters furthermore compensate disturbances caused by
interferences and distortions. After downsampling to the selected sampling frequency
(1 kHz to 100 kHz), the measurement system gets a high-quality signal which is
available via the FO-interface. „In our new parallel analog-digital converter, the
customer can determine the filter characteristics. This is of a great added value for
example in the field of Condition Monitoring where it is all about filtering frequency
components early on in the process“, Dr. Lettau explains.
The customer can also define the so-called “Function block“, by means of which
predefined, technology specific virtual signals can be calculated. With this function,
signal processing functions for special cases like calculating the RMS, determining
frequencies, measuring amplitudes as well as boosts and cuts in the frequency band
can be done. Another special feature of the ibaPADU-4-AI-U: The input signal level
for each channel can be adjusted in several stages from ±250 mV up to ±24 V.
Following up on successful PADU technology
„In addition to these new functions for acquiring and recording fast signals, ibaPADU4-AI-U also disposes of the well-known advantages of our PADU-technology“, Dr.
Lettau explains. The measurement system offers a simultaneous measured value
acquisition for each channel. The signals are sampled in parallel in order to prevent
falsifications. The analog inputs are electrically isolated, the terminals can be
connected without the risk of short circuiting. Using the ibaPDA-V6 online data
acquisition software, the user can moreover select and configure the signals
conveniently. Due to their connectivity, the manufacturer independent iba
measurement value acquisition systems can be connected to the automation systems
and bus technologies of all common manufacturers and generations. The data are
acquired, archived and analyzed across different systems.
