APCI-3600

The PCI noise and vibration measurement board APCI-3600 has been especially developed for acoustic processes in test applications in the industrial environment. It has 8 SE/diff. (+/-) inputs, 24-bit, 8 current sources for the connection of ICPTM-sensors8 digital inputs and 8 digital outputs, 24 V. 4 chronometer inputs (RS485) allow the parallel  revolution counting. The 8 analog SE/diff. (+/-) inputs have 1 A/D converter per channel and allow a simultaneous sampling with a frequency between 2 kHz and 200 kHz. An antialiasing filter to avoid sampling errors is available. Furthermore, the board is equipped with a software programmable  gain from 1 to 10 as well as an input coupling for AC, DC, GND. 64-bit drivers for Windows 8/7/Vista/XP and Linux as well as programming samples are included, real-time drivers for Windows and Linux are available on request.

Description

Acoustic processes in the field of testing are not limited to measurement of noise and vibration.
That is why the multifunctional PCI card APCI-3600 from ADDI -DATA performs almost all additional measurement tasks on the basis of a PC, thanks to its numerous numerous additional functions.

  • 8 analog inputs with coaxial SMB connectors
  • 4 count inputs (up to 1 MHz with 32-bit depth) for applications requiring exact exact determination of coordinates.
  • Current source for ICP™ sensors
  • Synchronous mode (cascading) of multiple APCI-3600 per master/trigger
  • Digital I/O
  • SDRAM memory module allowing transfer rates transfer rates up to 24 MB/s.

For fast integration of the board into special test machines, the machines, the card is delivered with drivers and programming programming examples.

Applications

The following applications can be realized with the APCI-3600 card:

  • Noise measurement with diagnosis of gearing errors or gear errors via FFT: encoders are connected to the timing inputs encoders are connected to the timer inputs and microphones to the analog inputs. The encoders determine the position of the and the analog inputs measure the noise of the noise of the system at a given position. For this purpose, the encoder and analog inputs are sampled synchronously: each analog measurement corresponds to a position of the chronometer. The quality of The quality of the gearing is then determined by FFT function.
  • Measurement of the transfer function of a “black box”.
  • Noise analysis, automatic vibration measurement systems for the validation of washing machines, measurements in the measurements in the automotive sector, etc.

APPLICATIONS

Active vibration damping

For this, a real-time regulation system is used, the MSX-Box, which continuously adapts the counterforce to the vibrations.
