Harsh environment closed loop servo<br />
inclinometers/accelerometers<br />
The Sensorex SX41200 and SX41400 series from Meggitt<br />
Sensing System are two families of rugged, gravity referenced<br />
closed-loop servo inclinometers/accelerometers designed for<br />
use in harsh environments.<br />
Available in 12 individual<br />
models per series, with<br />
angular measurement ranges<br />
from ±3° to ±90°, and choices<br />
of single axis (SX41200)<br />
and twin axis (SX41400) versions, their highly rugged design<br />
incorporates a galvanometric pendulum sensing element with<br />
hydromechanical damping, combined with an optical position<br />
sensor, with 4-20 mA or ±5 VDC (±5%) output, proportional to<br />
sine of the angle of tilt. Inertial sensing elements are contained<br />
wi<strong>thin</strong> rugged, watertight IP65 sealed aluminum housings.<br />
They are powered by a single, unregulated voltage supply and<br />
feature a bidirectional output. Additional options, available<br />
upon customer request, include a ±0.02% non-linearity error<br />
specification (excluding ±90° range), special bandwidth, zero<br />
offset (unipolar output) and special range and output signals.<br />
All Sensorex SX41200 and SX41400 series models conform to<br />
both <strong>Europe</strong>an EMC and railway testing standards.<br />

Powerline and wireless communications<br />
SoCs for smart energy management<br />
Greenvity Communications has developed the first hybrid<br />
system-on-chip (SoC) family that integrates powerline communication<br />
(PLC) and wireless capabilities on a single chip.<br />
The Greenvity Hybrii chip family<br />
supports both the HomePlug<br />
Green PHY PLC and ZigBee<br />
worldwide standards simultaneously<br />
to enable robust<br />
and intelligent connectivity<br />
for a variety of home and building energy management and<br />
electric vehicle applications. The first family members include<br />
the Hybrii-XL chip for smart grid, smart energy management,<br />
industrial and consumer applications, and the Hybrii-PLC<br />
device for rugged, high temperature conditions. Hybrii-XL<br />
enalbes smart grid products that integrate both PLC and<br />
ZigBee communication capabilities. The Hybrii chip automatically<br />
chooses the best medium to transmit energy-related<br />
data—wirelessly or via existing power lines—and extends the<br />
range to cover an entire home or building. If wireless nodes<br />
are noisy due to interference then PLC will be enabled and<br />
vice versa, ensuring reliable communication. The Hybrii-XL<br />
(GV7011) integrates HomePlug Green PHY PLC and ZigBee<br />
wireless functions for low cost and low power consumption.<br />
Both HomePlug Green PHY PLC and ZigBee can operate simultaneously.<br />
The GV7011 offers high performance with data<br />
rate up to 9.8 Mbps in PLC mode and 250 Kbps in wireless<br />
mode. The Hybrii-PLC chip (GV7012) was designed to support<br />
electric vehicle and electric vehicle supply equipment<br />
(EVSE) or battery chargers. It can support up to 9.8 Mbps of<br />
data rate over power line.<br />

High accuracy temperature sensor enables<br />
adjustable alerts<br />
Linear Technology Corporation has introduced the LTC2996<br />
high accuracy temperature sensor for 2.25 V to 5.5 V systems.<br />
The LTC2996 measures a remote diode’s temperature<br />
with ±1°C accuracy and its own die<br />
temperature with ±2°C accuracy<br />
while rejecting errors due to noise<br />
and series resistance. The device<br />
provides a voltage-proportional-toabsolute-temperature<br />
(V PTAT<br />
) output,<br />
as well as individual undertemperature and overtemperature<br />
alert outputs, defined by user-adjustable thresholds. No code<br />
is required to configure the device. With a 200 µA quiescent<br />
current, the chip simply provides a precise, space-saving,<br />
micropower temperature monitoring solution. Its accuracy,<br />
configurability and code-free operation caters to a wide<br />
variety of applications, including system thermal control, energy<br />
<strong>harvesting</strong>, desktop and notebook computers, network<br />
servers and environmental monitoring. Users can choose to<br />
measure internal or remote temperature and easily adjust the<br />
temperature thresholds with resistive dividers. Temperature<br />
conversions are updated every 3.5 ms to provide systems<br />
with sufficient time to react to alerts.<br />
