Pressure Sensors Certified for Hazardous
Industrial Environment |
| |
 |
January 12, 2007, Depew, NY, USA – PCB Piezotronics, Inc. (PCB®)
has introduced a series of dynamic, ICP® pressure sensors that have been
certified under ATEX and CSA for use in hazardous environments. These
sensors are widely used on pumps, compressors, power generation
equipment, and other machinery operating in hazardous environments. |
|
|
Series 102 and 121 pressure sensors are ideal for monitoring performance
of compressors, pumps, and gas turbines, because they measure dynamic
pressure events such as surges, pulsations, and spikes. These sensors
also detect wellhead acoustics to determine properties of mud & water.
Sensors may be used with ICP® signal conditioning and permit the use of
a variety of inexpensive two-wire cable systems. The low-impedance
signal may be transmitted over long cable distances, and the sensors may
be used in dirty environments with no signal degradation. ... |

‘Variable Area Flowmeter’ with CMOS-Sensor |
| |
 |
Measurement and regulation of gas flow. Floating-body or high-precision
flow meter: the user determines the device. Variable area flowmeters for
plant and apparatus construction are just as popular as ever. The
numerous advantages in daily practice are convincing: cost-effective
purchase, simple installation and handling, maintenance-free and
independent operation. |
|
|
The variable area flowmeter range from Vögtlin with precision
valves has distinguished itself for years with its high-quality, modular
construction. However, certain applications require measurement
accuracy, with respect to pressure and temperature independence, which
cannot be achieved with conventional variable area flowmeters. This is
where the ‘red-y compact’ thermal mass flow meters come into their own.
Alongside the advantages of the floating body, the devices offer
extremely precise and rapid measurement (accuracy 1 % of full-scale
value, dynamics 1:50) thanks to digital CMOS sensors. Measuring ranges
extend from 2 mln/min up to 450 ln/min air. The measurement is
independent of pressure and temperature. ... |

Highly Integrated DC motor controller
with Bridge predriver for Smart Actuators |
| |
 |
Melexis introduces the MLX81100 DC motor controller with embedded
Flash memory and CPU for automotive high current applications. DC motor
control, diagnostics and protection is greatly simplified with the
highly integrated MLX81100 and a few simple power NMOSFETs. The MLX81100
is the first member of the new ‘MelexCM’ family of automotive actuator
ASSPs with embedded Flash memory. |
|
|
Safety critical high current DC motor actuator applications, like
wipers, seatbelt retractor, steering column lock, electric brakes as
well as pumps, heaters and blowers can benefit most from Melexis new
line of embedded Flash memory microcontrollers. The high temperature
capability of the MLX81100 makes it particularly suited for engine flaps
like throttle, manifold, turbo and EGR. The MLX81100 like all ‘MelexCM’
products consists of a 5MIPS dual task Flash CPU die with a dedicated
high voltage die, which integrates voltage regulator, RC oscillator,
high voltage IO’s, LIN transceiver and ADC. Additionally the MLX81100
has an integrated programmable H-bridge predriver with low side shunt
measurement to enhance DC motor control applications. ... |

KROHNE OPTIFLUX with ceramics is used as
standard at BASF |
| |
 |
The largest chemical company in the world, BASF, has adopted the
OPTIFLUX 5300 electro-magnetic flowmeter as standard. The OPTIFLUX 4300
had previously passed a type test and been integrated to the standard,
and BASF has now also transferred the results to the versions with
ceramic measuring tube linings. |
|
|
This means that the OPTIFLUX 5300 is part of the worldwide framework
contract, making KROHNE an official global supplier of flow and
level measuring equipment to BASF. The flanged version of the OPTIFLUX
5300 from KROHNE is also available with the new high performance
ceramics for small nominal diameters from DN 15 to DN 100. The flanges
protect the ceramic lining of the OPTIFLUX from damage, particularly
during installation. The flanged version also offers the customer
increased protection against leakage of the process medium in case of
fire. KROHNE has drastically reduced the number of parts that come into
contact with the process medium. Apart from the ceramics, only the seals
and the electrodes now make contact. Electro-magnetic flowmeters ... |

Elevator Modernization Made Easy |
| |
|
Modernizing existing elevator equipment is more valid today than ever
before. This does not simply mean freshening up the aesthetics of the
older equipment. Existing elevator equipment often needs to be
modernized due to new safety regulations, higher comfort demands, but
also for increased efficiency or for the intrinsic value of the
buildings. As one of the leading manufacturers of optical sensors and
controller components for the elevator industry, CEDES offers
elevator companies many interesting solutions with which they can adjust
their existing equipment very economically and easily to the new
requirements. cegard/3D – Three-dimensional safeguarding of elevator
entrances. There are application areas, such as retirement homes or
hospitals, where the safeguarding of the door using solely optical door
edges no longer suffices. CEDES specially developed cegard/3D for these
“no compromise” applications. Alongside the danger zone between the
doors, the 3D system additionally monitors the area in front of the
doors. ... |

Light Curtains Ensure Correct Objects
Picked |
| |
 |
Object100 light curtain. Absolute certainty. The technical term “Poka
Yoke” means the prevention of unintentional errors using technical
equipment. So-called “Poka Yoke” systems on racks ensure that the
correct object is picked and the wrong parts aren’t accidentally chosen.
They assist the rack user in removing the right part from the right
place. |
|
|
The main cause for incorrect deliveries and respectively wrong
components being used is eliminated and thus potential consequential
costs are kept to an absolute minimum. Object100 support. With the
Object100 light curtain, picking systems can be quickly and simply
converted to poka yoke capable systems. Due to the large operating range
and the dense web of beams, larger areas can also be dependably
monitored. The shorter reaction time of the light curtains ensures
optimal efficiency during object picking. The extraction area can be
flexibly configured through the equipment controller. Thanks to the very
compact emitter and receiver light curtains, the Object100 can also be
mounted without any problems into areas where space is very limited. The
slender light curtains do not disrupt the function of the rack itself in
any way. ... |
