    W av e spotWave is a trademark of Vallen Systeme and the type designation of a single channel AE measurement system that can be operated by a mobile device or a PC. It has a USB interface for communications and power supply.

  • Page 12: General Information About The Usage

    General Information about the Usage A spotWave device is part of the spotWave measurement system (short: spotWave system). The single channel spotWave system can be used for measuring acoustic emission. It can be operated in an acquisition mode or logging mode. Figure 1 shows a block diagram of the spotWave system in acquisition mode. Figure 1: spotWave measurement system (acquisition mode) as block diagram consisting of one AE sensor, one coupling check transducer (CCT), the spotWave device, and a PC or mobile device running the data acquisition program storing the measurement data.

  • Page 13: Environmental Conditions

    intention is to measure signals with amplitudes in the range of a few Microvolts to Volt and a frequency range of 20 kHz to 500 kHz. As of these characteristics it is suited for measuring Acoustic Emission. The coupling check transducer is driven by the spotWave device and can be used as an artificial source of acoustic emission for (i) checking the mounting quality and function of the AE sensor, (ii) measuring the time-of-flight or (iii) measuring the speed of sound.

  • Page 14: Reasonably Foreseeable Misuse

    Reasonably Foreseeable Misuse The spotWave device shall only be used in the foreseen measurement frequency range. Do not use it with sensors that provide output signals in a frequency range too low (less than 1 kHz) or too high (more than 1 MHz).

  • Page 22: Operating A Spotwave Device

    16.2. Connecting a Coupling Check Transducer Only connect a device from Vallen Systeme that is labelled and specified as Coupling Check Transducer (CCT). For connecting the CC-transducer to the spotWave device use the appropriate cable (product code: CBL-1- 1M2-V70).

  • Page 23: Measurement Mode

    A spotWave device measures features of an AE signal. The measured data is stored to a feature file that meets the SQLite3 standard. The file extension of the feature file is *.pridb. Vallen AE Suite analysis software can read and process this file.

  • Page 24: Command Set

    The spotWave is a USB CDC (Communications Device Class) device and can be controlled with serial commands. Windows uses the usbser.sys driver by default, which exposes a virtual COM port. If the Vallen AE Suite Software is installed, a setup information file for the spotWave device (C:\Vallen\Drivers\spotWave\vspwv1.inf) is installed to use the low-level and stable winusb.sys driver.
