New Wireless Sensors for Humidity,
Temperature and CO2 |
| |
 EE240
wireless sensors from E+E Elektronik are the ideal solution for
high quality, wireless measurement of humidity, temperature or CO2. With
the introduction of state-of-the-art wireless data transmission, E+E
Elektronik, the sensor specialist, is expanding its expertise into
wireless sensor systems. Up to three intelligent probes can be connected
to each transmitter. Each probe operates independently and can be hot
swapped. Remote probes allow the sensing head to be placed at a distance
of up to 10m away from the transmitter. These features make the E+E
wireless sensors especially suited for industrial applications that
require sensors to be routinely recalibrated without affecting network
operation. The measured values can be read directly off the display on
the transmitter or read remotely using your web browser from any PC in
the company network. The base station features a digital Ethernet
interface for effective connection to the network and data analysis. The
integrated web server allows you to easily and individually configure
the wireless sensor network from any PC without ... |

Energy-efficient ventilation with the
Climate Guard: optimum indoor climate with minimum energy expenditure |
| |
 The
Climate Guard from J. Dittrich Elektronic is a network-compatible
multi-sensor system that facilitates demand-controlled, energy-efficient
ventilation for special-purpose buildings. It measures the important
parameters of indoor air: the carbon dioxide concentration by means of a
dual beam infrared photometer (NDIR); the temperature by means of a
bandgap sensor; and the relative humidity by means of a capacitive
polymer. Both the power supply and digital transmission of measured
values are effected via an Ethernet connection (PoE). Since the Climate
Guard has its own web server, it can be integrated directly into a local
network or the Internet and data called up using a web browser. This is
ideal for automated buildings. All three measured variables increase ... |

Novel CO2 Sensors for Closed Circuit
Rebreathers |
| |
|
Synkera Technologies, Inc. is currently developing solid-state,
conductiometric sensors for monitoring carbon dioxide (CO2) under a SBIR
Phase I grant from NOAA. The focus of the funded work is the development
of small, low-power sensors to be included in the breathing loop of
closed circuit rebreathers that can monitor for a breakthrough of the
CO2 scrubbing system. The inclusion of a CO2 sensor in closed circuit
rebreathers will make the dive equipment safer and allow for more
widespread use. The initial SBIR effort is the development of sensors
and electronics and will be followed-up by the integration of the
sensors into rebreathers for testing of prototype units. Due to
significant cost advantages, it is anticipated that the devices will
expand CO2 sensing for applications served by currently available
technology, primarily infrared (IR) sensors, and open up new sensing
opportunities. A particular area that these novel sensors are expected
to impact is demand control ventilation (DCV). These new solid-state
sensors are expected to demonstrate performance comparable to IR sensors
currently used in cost sensitive applications. Fabrication of the
sensors in a unique surface mount geometry is ideal for integration with
electronic components, allowing for very small sensing modules. The CO2
sensors will have the following unique characteristics ... |

The World’s Most Energy-Efficient CO2
Sensor Module |
| |
 With
its unparalleled low power consumption the new EE892 from E+E is
a highly impressive CO2 sensor module. Features such as an adjustable
measuring interval enable optimum adaptation to specific applications
while maintaining an average current consumption of less than 60μA. This
makes the EE892 CO2 sensor module the ideal battery-operated,
energy-saving device. The CO2 sensor module was specially developed for
OEM applications and high-volume production. The digital interface and
extremely compact design facilitate clear-cut integration in mobile and
energy-sensitive applications such as data loggers or demand controlled
ventilation. The CO2 load cell is based on infrared technology (NDIR)
and, thanks to the patented E+E autocalibration process, it is
completely maintenance-free. Ageing effects are compensated
automatically to guarantee outstanding ... |

MikroKera™: New Low Power Micromachined
H2 sensors and VOC Sensors Available |
| |
 Synkera
Technologies, Inc.: In response to increased demand for gas sensors
of all types and requests for low power versions of Synkera sensors,
Synkera has introduced the first two products in our new MikroKera™
line. Designed for low power, reliability and excellent performance, the
new MikroKera™ H2 sensors and VOC sensors meet the needs of customers in
industrial health and safety, air quality monitoring and process control
applications. Both the new MikroKera™ and our current ProKera™ sensors
accommodate the complex requirements of instrument and systems
manufacturers. The MikroKera™ family of sensors utilizes Synkera’s
unique micromachined, nanostructured ceramic microsensor platform made
from anodic aluminum oxide (AAO). This patented microsensor platform
offers an unprecedented combination of performance, reliability and
scalability that will ultimately facilitate development of a complete
family of sensors for existing and emerging industrial and commercial
applications. The first two sensors use the same sensing materials that
have been successfully deployed in our longstanding ProKera™ VOC and
hydrogen (H2) sensors ... |

mySENS® – Micronas Announces Major
Breakthrough In Gas Sensing Technology Based On Standard CMOS |
| |
 Micronas,
a leading supplier of innovative application-specific IC and sensor
system solutions for automotive electronics, announces a major
breakthrough in gas sensing technology. Based on Micronas’ mySENS
platform, this innovative technology rests upon standard CMOS technology
which has been utilized and proven in Micronas’ current products for
automotive and industrial applications for many years. “Leveraging its
extensive experience in Hall-effect sensors, Micronas is in an ideal
position to use existing know-how for developing new sensor technologies
for a broad range of markets and applications,” says Peter Zimmermann,
Director Marketing at Micronas. “With the mySENS technology we are
expanding our sensor expertise towards the field of gas sensing to
target industrial as well as automotive applications.” Similar to its
success story within the Hall-effect sensor market, where Micronas
pioneered the CMOS Hall-effect sensor, mySENS technology enables the
combination of sensing elements with standard electronic devices such as
amplifiers, logic circuits, and memories. Such integration capability
will significantly contribute to the miniaturization of existing gas
sensing applications and – as a result of its small size – enable
completely new ... |

Exact measurement of residual oxygen
content in furnace exhaust gas |
| |
 The
MF010-O-LC dynamic oxygen measuring system from J. Dittrich
Elektronic is the fail-safe way to determine the residual oxygen
content in furnace exhaust gas. With the help of a coupled controller
the excess air specified for reasons of safety can be minimised and
combustion in the furnace optimised, thereby increasing efficiency. In
this way it is possible to compensate for fluctuations in the quality of
fuels for modern wood firing. Contrary to a lambda probe which measures
the relative oxygen content, the extremely robust oxygen measuring
system determines the absolute content, i.e. the oxygen partial pressure
in the exhaust gas. For this reason, fluctuations in air pressure,
humidity and temperature have no influence on the accuracy of the
measurement. The system is calibrated electrically, without reference
gas and without additional personnel, in atmospheric air at the end of
the furnace’s ventilation phase, thereby reducing maintenance work. This
is made possible by a dynamic zirconium dioxide sensor ... |
