'Do not operate' quake-linked disposal wells: EPA draft report
2013-07-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Energy Wire: U.S. EPA officials say oil and gas wastewater injection wells that are causing earthquakes should stop operating if there's no way to stop the shaking. But there is a variety of other options to consider first, according to a "decision model" outlined in a draft report obtained by EnergyWire. That includes scaling back how much well owners can inject, requiring more data collection or public education about "the complexities of injection-induced seismicity." The 341-page document represents...

RF Coaxial Attenuators operate up to 4 GHz.
2013-07-18 14:30:16| Industrial Newsroom - All News for Today
Available in 3 GHz and 4 GHz models, 50 Ω Fixed RF Microwave Attenuators can be ordered with combinations of SMA and N connectors. Units have peak power ratings from 5–200 W, depending on design, and come in 1, 2, 3, 6, 10, 15, 20, 30, and 40 dB varieties. RoHS and REACH compliant, attenuators are manufactured with large aluminum heatsink cooling fins that quickly dissipate heat and allow operation from -55 to +125°C.

Fast Switching NPT IGBTs operate in harsh environments.
2013-07-18 14:30:15| Industrial Newsroom - All News for Today
Offered in 45, 70, and 95 A current ratings, 650 V non-punch through (NPT) insulated bipolar gate transistors (IGBTs) enable switching speeds up to 150 kHz – further improved when transistors are paired with SiC free-wheeling diodes. Products are based on advanced Power MOS 8™ technology and leverage wafer thinning process, reducing total switching losses, and may be paralleled (positive temperature coefficient of Vcesat) to improve reliability in high-current modules.

Servomotors operate without external cooling.
2013-07-16 14:31:12| Industrial Newsroom - All News for Today
Available in standard, high-dynamic, and high-inertia versions, Generation II Simotics 1FK7 Servomotors feature 7 shaft heights, Quick-Connect power connector, and 20- or 24-bit field replaceable encoders in 10 styles. Encoders are mechanically and thermally decoupled from motor, optimizing continuous power. Supplied with or without holding brake, motors provide 2.5% torque ripple, cross profiling, Siemens Drive-Cliq interface for field commissioning, plain shaft or keyway design, and IP ratings.
