Shock & Vibration AAC Offers Silicone Gel Products to Isolate Vibration on UAV Cameras Advanced Antivibration Components (AAC) offers a number of different silicone gel products for isolating vibration in UAV (unmanned aerial vehicle) applications. Surveillance UAVs make use of cameras to obtain visual intel in military and other applications. Because there is significant vibration caused by turbulence and the propulsion of the system itself, vibration damping is crucial for obtaining smooth camera footage. AAC offers silicone gel spring mounts, pads, tapes and chips, but the bolt mounts are of particular interest for UAV applications. Identified as the V10Z61MS, V10Z61MA and V10Z61MB series, the mounts have a low profile design to minimize image distortion. They have a temperature range of -40°C to 200°C. IMI Sensors Launches Linear Adjust Mechanical Vibration Switch IMI Sensors has released the new mechanical vibration switch, Model 685A09. The model features a unique design that provides added sensitivity adjustment. IMI has developed this Linear Adjust Mechanical Vibration Switch for use in various applications such as cooling towers, fin fans, large exhaust and vent fans, HVAC systems, blowers and motors. The mechanical vibration switch has a design that provides better trip sensitivity adjustment, which allows a user to better control the trip level in the switch and improve protection of their equipment. Additionally, due to the design and manufacturing processes used to build the switch, it is more cost competitive. Some of the other benefits of the mechanical vibration switch include low cost protection for critical machinery, better sensitivity repeatability on reset, DPDT relay, 10 amp dry contacts and120, 240 VAC or 24 VDC options. Piezoelectric Accelerometers for Vibration and Shock Work Columbia Research Laboratories has developed a group of piezoelectric general purpose accelerometers that are designed for a wide range of shock and vibration applications. The 3000 series standard size units include many with all welded construction that are hermetically sealed for use in dirty and humid environments. The unique design of the piezoelectric seismic system inherently provides complete mechanical isolation of the sensing element. This design makes the sensors insensitive to mounting torque, body strains, cable vibration, cable whip, pressure variations and most heat transients. The signal is self generating, requiring no external power source. These units offer wide frequency ranges and are available in high temperature versions. The 5000 series are smaller and lighter in weight than standard 26 units. Characteristics are almost identical to standard units except that with the smaller, lighter units, higher natural frequencies and shock levels can be obtained due to their reduced mass. Sensitivities, however, are somewhat lower. For best performance, Columbia model 4601 Charge Amplifier, series 5684 airborne amplifiers, or 5421 power supply combined with inline charge converter model 5810 are recommended for use with these high impedance accelerometers. Additional mounting adapters and cable assemblies are also available. Betex VibChecker Vibration Monitor Meter From QBC is for Quick Vibration Surveys A Betex professional VibChecker vibration monitor meter from Quality Bearings & Components (QBC) is a light and compact-sized instrument designed for quick and accurate vibration surveys. The meter, identified as the model TB-C780201, provides portable vibration measurement in the 10 to 1,000 Hz frequency range. Measurement results are immediately and automatically evaluated against ISO standards. Green, yellow and red LEDs indicate vibration severity and a real time FFT spectrum is produced for easy pattern recognition. Results can be stored for documentation and follow-up. With its built-in probe, easy button operation and clear symbols, VibChecker is an all-set-to-go instrument. Just point the probe and measure to locate vibration-related problems. VibChecker is used to trend vibration levels on fans, motors, pumps, compressors and other types of rotating process machinery. In most cases, vibration measurement can detect a problem long before damage to the machine is done. The repair of equipment failing while in service is many times more costly than planned repairs made possible through vibration monitoring. SensorCloud Demonstrates MathEngine Analytics For Enhanced Sensor Data Performance Indicators Lord MicroStrain’s cloud-based sensor data platform, SensorCloud, provides big data visualization and analytical tools to identify anomalies in terabyte vibration data. SensorCloud was used to rapidly plot, navigate and extract key performance indicators on 100 billion points of time synchronized vibration data. The 1 terabyte dataset was composed of 100 kHz machine vibration taken in 1 second bursts every ten minutes and simulated more than 19 years. Embedded analytics allowed users to identify vibration frequency deviations in seconds and support long-term condition based maintenance. The MathEngine analytical toolkit supported the development and implementation of processing scripts directly on SensorCloud. By plotting a virtual peak frequency channel, individual burst anomalies were immediately identified. Fast graphing capabilities enabled drill-down to raw waveform views within seconds. “Sensors are increasingly generating big data,” said Ben Corneau, manager of Software Engineering, Lord MicroStrain. “In order to extract actionable information, users need powerful data management, visualization,and analytical tools. When applied to real-time sensor networks, MathEngine outputs can be fed directly to the Alerts App for fully customized email and SMS alerting.” September/October 2013 www.ElectronicsProtectionMagazine.com http://www.ElectronicsProtectionMagazine.com
