Meggitt Sensing Systems' Endevco
model 6233C is a highly rugged, high-temperature piezoelectric charge output
accelerometer, designed for continuous operation to +482C (+900F) with long Mean Time Before
Failure (MTBF), making it useful for the high-precision vibration monitoring of
high-temperature jet and turboprop engines, helicopter and rotorcraft HUMS, gas
turbines and nuclear power plant machinery and equipment.
With available standard ranges of 10, 50 and 100 pC/g, the
Endevco model 6233C offers a highly balanced differential output, performance stability
over temperature and a wide operational bandwidth. Units are case isolated and
feature standard three-point ARINC mounting and a rugged 2-pin 7/16-27 UNS 2A
threaded receptacle. As a self-generating device, the accelerometer requires no
external power source for operation. At such high temperatures, the use of a
charge amplifier or remote charge converter that can accept a 100 O source
resistance is required.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
