A wide range of low-power industrial sensors and controllers are turning to alternative sources of energy as the primary or supplemental means of supplying power. Ideally, such harvested energy will eliminate the need for wired power or batteries altogether. Transducers that create electricity from readily available physical sources such as temperature differentials (thermoelectric generators or thermopiles), mechanical vibration (piezoelectric or electromechanical devices), and light (photovoltaic devices) are becoming viable sources of power for many applications.
This week the hot topic of nuclear power was overshadowed by President Obama’s announcement to restrict the use of nuclear weapons and reduce nuclear stockpiles—along with Russia—by about one-third. If you missed it, the President specified that the use of nuclear weapons would only be considered against countries that are not in compliance with the nuclear Non-Proliferation Treaty; for example, North Korea and Iran.
The LK-G5000 Laser Displacement Sensor from KEYENCE (Woodcliff Lake, NJ) now features a RS-CMOS sensor and provides a 392 kHz sampling rate that is eight times faster than previous models, with a 0.01µm repeatability. The sensor is now more compact than previous models, making it easy to mount in tight production environments.
Metabo Corporation (West Chester, PA) now offers the 5” W11-125 Quick Compact Class Angle Grinder, which features a quick wheel change system that makes changing discs both safe and easy, without the use of tools. The W11-125 is ideal for cutting and grinding applications with a Vibratech side handle that reduces vibration up to 60 percent, lowering the risk of white finger syndrome, according to the company.
Konecranes (Springfield, OH) has developed RopeQ, a reliable system that evaluates the working condition of wire ropes using a proprietary Non-Destructive Testing (NDT) method. The RopeQ uses electromagnetic technology to assess the inner and outer wires and strands of a rope, which ensures accurate and repetitive inspection results.
The VoltageVision Power Warning Alerts from Grace Engineered Products (Davenport, IA) provide electricians with electrical safe information while working on de-energized systems. The system is now available in a solid-on model type, which features LEDs to illuminate the presence of voltage.
Danray Products LLC (Rockford, IL) introduces its new fan guard safety scale, which checks the openings in fan guards for compliance with OSHA 29 CFR 1910.212(a)(5). The OSHA regulation states that fan blades must be covered with a guard, which may not have openings more than ½”.
A line of AISI 1018 steel shaft collars from Stafford Manufacturing Corp. (Wilmington, MA) can be machined to facilitate the welding of components such as brackets, cams, lever arms, mounts, pins, and rods. The collars come in one- and two-piece styles that can be further machined to make fixturing easier when creating welded assemblies.
Blackmer (Grand Rapids, MI) announces its SMVP Series Sliding Vane Pump, which combines the energy-efficiency of sliding-vane technology with a seal-less magnetic coupling. The SMVP offers zero shaft leakage when dealing with hard-to-seal surfactants, fatty acids and oils, glycerin, additives, and more.
Cleveland Gear Company, Inc. (Cleveland, OH) is broadening its product offerings to a new line of shaft mount reducers and accessories (tapered bushing kits, belt guards, torque arms, motor mounts, and backstop assemblies). The gears are available in eight CGSM sizes (2-9), input horsepower from 1/3 to 125, and output rpm from 4-6 up to 118-125.
WASHINGTON (AP) — Toyota agreed on Monday to a record $16.4 million fine for its slow response to sticking gas pedals — the equivalent of a little more than $2 for every vehicle the company sold around the globe in 2009. But the fine, the maximum under the law, could be simply a downpayment in the long run: The Japanese auto giant still faces dozens of private lawsuits, which have been combined before a federal judge in Santa Ana, Calif.
PONTOTOC, Miss. (AP) — A Canadian company has scaled back its initial plans to build a biofuels plant in Pontotoc County.
