Wireless module for sound and vibration applications
This wireless dynamic signal acquisition module allows engineers and scientists to stream vibration data wirelessly over Wi-Fi to distributed monitoring systems, while eliminating the cost and clutter of cabling.
The NI WLS-9234 wireless dynamic signal acquisition module allows engineers and scientists to stream vibration data wirelessly over the IEEE 802.11g (Wi-Fi) standard to distributed monitoring systems, eliminating the cost and clutter of cabling. The module offers four simultaneously acquired input channels, each with 24-bit resolution and a 51.2 kS/s maximum sampling rate. It delivers 102 dB of dynamic range and incorporates software-selectable ac/dc coupling and integrated electronic piezoelectric signal conditioning for accelerometers and microphones.
The module also relays data wirelessly over a Wi-Fi network, allowing for easy distributed I/O, and provides support for various wireless security protocols including WEP, WPA and WPA2 (IEEE 802.11i) to protect data and network integrity. It also features support for direct Ethernet connection.
The module is compatible with the NI Sound and Vibration Measurement Suite, which includes NI Sound and Vibration Assistant stand-alone, interactive software for quickly acquiring, analyzing and logging acoustic, noise and vibration data. The Sound and Vibration Measurement Suite also extends analysis functionality with NI LabVIEW VIs for performing audio measurements, octave analysis, frequency analysis and order tracking for automotive, military and aerospace and mechanical and structural designs.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
