PCB® Introduces Miniature Accelerometer
Weighing 0.20 Grams for Vibration Screening of Circuit Boards, Disk
Drive Mechanisms, PDA’s & Mobile Phones |
| |
 Depew,
NY, USA – PCB Piezotronics (PCB®) has introduced Model 357A19, a
very miniature charge output accelerometer, designed for performing
shock and vibration studies in space-restricted locations and on small,
lightweight structures. The unit occupies a 0.11 x 0.16 x 0.27 inch (2.8
x 4.1 x 6.9 mm) envelope, and weighs a mere 0.007 ounces (0.20 grams),
for minimal mass loading of a test article. The unit connects to
laboratory-style charge amplifiers or in-line charge converters, which
condition an output signal for recording or analysis. Model 357A19
features an operating temperature range of -100 to +350 °F (-73 to +177
°C) and is ideally suited for thermal cycling and vibration stress
screening of circuit boards, disk drive mechanisms, mobile phones,
PDA’s, and other electronic devices. Other applications include NVH
studies on automotive parts and modal analysis of small structures and
satellite components. The sensor is structured with a shear mode,
piezoceramic sensing element and produces a 0.35 pC/g output signal,
with frequency response of up to 20 kHz and resonant frequency of
greater than 70 kHz. Additional features include

LVDT 0.25% accuracy, Ex-stock to 4 weeks
delivery |
| |
|
Recent improvements to the design and manufacturing methods for the LVDT
range from Applied Measurements have resulted in improved
accuracy and quicker delivery. They are now able to offer the option of
0.25% accuracy and a maximum delivery of 4 weeks. There are three main
types, Miniature, Economy and Industrial. Each of these types is
available in several mechanical and electrical configurations.
Mechanical options include; the plain core, the plain core with
extension rod ( free or guided), spring loaded or with rod ends. The
basic sensor without integral electronics operates from an ac supply and
provides an ac output signal. The Economy and Industrial models are also
available with standard ac operation, or with integral signal
conditioning. The integral amplification requires a dc supply and
provides either a 4-20mA, 0-5Vdc, 0-10Vdc or +/-2.5Vdc output options.
Stroke lengths available range from +/-0.25mm with the miniature series
to +/-550mm with the Economy and Industrial models. Environmental
sealing ranges from IP40 for the miniature series through IP54 for the
Economy series to IP65 and 68 for the Industrial Series. Special designs
are also available including models for use in pressurised environments.
The LVDT range is supported by a comprehensive selection of analogue and
digital signal conditioning systems to provide fully calibrated ready to
use systems.

IMI Sensors New ICP® Accelerometer Alarm
Transmitter for Monitoring Unbalance and Misalignment on Motors, Pump
Sets and Other Rotating Equipment |
| |
 Depew,
NY, USA – The new Model 682A08 Vibration Transmitter from the IMI
Sensors division of PCB Piezotronics (PCB®) is an all-encompassing
ICP® accelerometer signal conditioner, complete with dual semiconductor
relay alarms and 4-20 mA signal transmission, for continuous monitoring
of critical machinery. The product’s versatility makes it ideal for
monitoring unbalance and misalignment on motors, pump sets and other
rotating equipment. This module provides excitation power for industry
standard 100 mV/g (10.2 mV/(m/s2)) ICP® accelerometers, and has the
capability to integrate the signal into velocity. The product comes
standard with selectable low pass filters at 1k Hz or 10k Hz, and high
pass filters at 3 Hz or 10 Hz. Model 682A08 retransmits an acceleration
or velocity signal as a 4-20 mA signal for trending and simple interface
with PLC, DCS, and SCADA systems. It also outputs the raw vibration
signal from an accelerometer for frequency analysis and system
diagnostics. It is DIN rail mounted, 24 VDC powered, and is an
economical solution for ICP® signal conditioning and alarming, in a
simple, compact design.

MOST Cooperation Steering Committee
Welcomes Commitment of Harman/Becker and SMSC to Open Data Link Layer of
MOST |
| |
|
Karlsruhe (Germany) - The Steering Committee of MOST Cooperation,
the cooperative established to promote the infotainment network standard
known as Media Oriented Systems Transport (MOST(r)), and whose
membership consists of Audi, BMW, DaimlerChrysler, Harman/Becker and
SMSC (Nasdaq: SMSC), has announced today that it welcomes and embraces
the decision by Harman/Becker Automotive Systems and SMSC to open the
details of their proprietary Data Link Layer for new and current
generations of the MOST multimedia network. In a press release on
October 1st, SMSC and Harman/Becker announced their intention to make
their detailed Data Link Layer technology for existing and future
generations of MOST available via a royalty bearing license in a
step-wise process linked to market growth. They also announced that a
detailed Data Link Layer specification for the first generation, MOST25,
has already been made available and can be requested on SMSC's website
by members of the MOST Cooperation. A license agreement to the related
patents of both companies can be requested via the same webpage.

e2v Selects Jazz Semiconductor for next
generation analogue to digital converter (ADC) products |
| |
|
e2v, a leading developer and manufacturer of specialised
components and subsystems and Jazz Semiconductor®, the leader in
Analog-Intensive Mixed-Signal (AIMS) foundry solutions and wholly owned
subsidiary of Jazz Technologies™ Inc., today announced that e2v has
chosen Jazz’s 0.18-micron SiGe BiCMOS process, SBC18HX, for the
manufacture of its next-generation high resolution programmable data
converter products. e2v and Jazz have already demonstrated their
successful collaboration on e2v’s award winning 12-bit Analog-to-Digital
Converter (ADC) developed using Jazz Semiconductor’s 0.35-micron SiGe
BiCMOS process, SBC35. e2v received the 2007 EE Times Ultimate Product
ACE Award for the World’s Fastest Monolithic 12-bit ADC (AT84AS001TP).
The AT84AS001TP is a 12-bit A/D Converter that can provide 500 Msps data
conversion from a single monolithic chip. This breakthrough in ADC
design allows system designers to accurately digitize intermediate
frequency (IF) signals with frequencies up to 500 MHz at twice the
sampling rate of conventional 12-bit ADCs. As a result of combining
Jazz’s high-speed silicon technology and e2v’s proprietary chip
architecture, a new 12-bit ADC standard has been set without
compromising on power consumption, dynamic range or linearity.
