Overview
Simple, Secure, Wi-Fi Data Acquisition
Wi-Fi data acquisition is an extension of PC-based data acquisition to measurement applications where cables are inconvenient or uneconomical. NI Wi-Fi data acquisition (DAQ) devices combine IEEE 802.11g wireless or Ethernet communication; direct sensor connectivity; and the flexibility of NI-DAQmx driver software for remote monitoring of electrical, physical, mechanical, and acoustical signals. NI Wi-Fi DAQ devices can stream data on each channel at up to 250 kS/s. In addition, built-in NIST-approved 128-bit AES encryption and advanced network authentication methods offer the highest commercially available network security. With the flexibility of NI LabVIEW graphical programming and the ubiquity of 802.11 network infrastructure, NI Wi-Fi DAQ makes it easy to incorporate wireless connectivity into new or existing PC-based measurement or control systems.
The NI WLS-9234 is a four-channel IEEE 802.11 wireless or Ethernet C Series dynamic signal acquisition module for making high-accuracy audio frequency measurements from integrated electronic piezoelectric (IEPE) and non-IEPE sensors. The WLS-9234 delivers 102 dB of dynamic range and incorporates software-selectable AC/DC coupling and IEPE signal conditioning for accelerometers and microphones. The four input channels simultaneously digitize signals at rates up to 51.2 kHz per channel with built-in antialiasing filters that automatically adjust to your sampling rate.

Application and Technology
NI WLS-9163 and C Series Hardware
Each NI WLS-9234 wireless sound and vibration device is a combination of an NI WLS-9163 wireless carrier and an NI 9234 C Series measurement module. The WLS-9163 provides both IEEE 802.11g and Ethernet connectivity back to a host PC. You can synchronize a WLS-9163 with other devices by using two onboard individually programmable digital trigger lines to export or import sample clocks, start triggers, pause triggers, and reference triggers.
C Series modules provide direct sensor connectivity and built-in signal conditioning for a variety of measurements, including temperature, strain, acceleration, current, and voltage. In addition to the WLS-9163, these modules may be used interchangeably for measurement and control applications with different chassis, including NI CompactDAQ and CompactRIO, and the NI USB-9162 and NI ENET-9163 carriers.
Figure 1. Each NI Wi-Fi DAQ device combines an NI WLS-9163 carrier and an NI C Series module to provide wireless sensor measurements.
You may purchase WLS-9163 carriers and select C Series modules separately or together in a kit as WLS-9xxx devices.
Wireless Security
NI Wi-Fi DAQ devices implement the highest commercially available wireless network security standard, IEEE 802.11i (commonly known as WPA2 or WPA2 Enterprise), including network authentication and data encryption. IEEE 802.1X authentication ensures that only authorized devices have network access, and encryption prevents data packets from being intercepted. NI Wi-Fi DAQ devices support multiple Extensible Authentication Protocol (EAP) methods that provide for mutual authentication between the data acquisition devices and wireless access points (WAPs). These devices also support the Advanced Encryption Standard (AES), a 128-bit cryptographic algorithm endorsed by the National Institute of Standards and Technology for use in many U.S. government facilities. By using standard security protocols, NI Wi-Fi DAQ devices make it easy to add wireless measurements to existing IT networks safely.
TEDS Compatibility
IEEE 1451.4, also known as TEDS (transducer electronic data sheet), technology consists of a standardized set of templates for specific sensors that store information such as manufacturer, manufacture date, calibration data, sensor-specific setup data, and more. TEDS is typically implemented on the sensor side via an onboard EEPROM. With this, the sensor has all of the information needed for setup and calibration stored locally, so you no longer have to keep up with paper data sheets. On the instrumentation side, the measurement system must have the capability to read and understand the TEDS data from the sensor. The WLS-9234 has the capability to read TEDS information for TEDS-enabled sensors.
Analysis Software
The WLS-9234 is well-suited for noise and vibration analysis applications. The NI Sound and Vibration Measurement Suite, which specifically addresses these applications, has two components: the NI Sound and Vibration Assistant and LabVIEW analysis VIs (functions) for power spectra, frequency response (FRF), fractional octave analysis, sound-level measurements, order spectra, order maps, order extraction, sensor calibration, human vibration filters, and torsional vibration.
