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.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
