PRESS RELEASE
E+E Elektronik at SENSOR+TEST 2013
Sensors and transmitters all from one source
(Engerwitzdorf, 30.4.2013) At SENSOR+TEST 2013 from 14th – 16th May in Nuremberg, E+E
Elektronik will be exhibiting as an expert and innovative partner for the measurement of
relative humidity, moisture in oil, dewpoint, air velocity, CO2, flow and temperature. "Everything
from one source" is the credo of the Austrian sensor specialist. This is because all E+E
transmitters are based on sensor elements developed and produced in-house. This means that
visitors to the E+E trade show stand in Hall 12, Stand no. 12-139 can expect not both the latest
sensor innovations, and transmitters for the industrial and HVAC sectors.
Sensors for humidity, CO2, oxygen and flow
Calibrated SMD humidity sensor
The HCT01 humidity and temperature sensor combines high quality thin-film sensor technology that
has been proven over the long-term, with standardised SMD mounting. The qualifications in place for
this element, based on the ISO/TS16949 standard, underlines the high quality of the sensor. The precalibrated capacitive humidity sensor makes time-consuming humidity calibration superfluous. The
optional temperature measurement is carried out using a high-precision thin-film element - a must for
precise dewpoint measurement. The special protective coating on the active sensor surface makes the
element particularly insensitive to contamination. The capacitive sensor signal can be integrated costeffectively into an existing µP evaluation, permitting maximum choice in the choice of supplier.
CO2 sensor for OEM applications
The CO2 EE891 sensor module has been developed especially for production in large unit quantities
and for OEM applications. The CO2 sensor is based on infrared technology (NDIR). Thanks to the
patented E+E autocalibration process, the sensor is maintenance-free. This compensates for ageing
effects and ensures excellent long-term stability. A digital interface and the minimal-sized design
permit very easy integration into devices, e.g. for controlled living space ventilation or data loggers.
New O2 sensor
The oxygen content plays a critical role in many applications. For example, this means that in
combustion processes, efficiency increases are achieved and the efficiency is optimised via the
regulation of the oxygen concentration. The O 2 sensor developed by E+E Elektronik functions in
accordance with the amperometric measuring principle. With a measurement range for the oxygen
concentration from 0 to 100%, it is suitable for virtually any conceivable application. The compact
design with integrated heater structure, linear limiting overload characteristic and response times in
the seconds range are further outstanding features of the E+E oxygen sensor. After the first pilot
projects in 2013, the start of series production is planned for the beginning of 2014.
New flow sensor
The new VTQ flow sensor from E+E Elektronik is based on the hot film anemometer principle. The
familiar disadvantages, such as high sensitivity to contamination, low mechanical load capacity,
minimal reproducibility of the characteristics, long response times, high angle-dependence or a limited
measurement range, have been removed in developing this element. This is achieved via the
combination of the tried and tested E+E thin-layer sensor, mounted onto extremely thin glass with the
latest transfer moulding technology, complex simulations and many years of experience from E+E
Elektronik in the field of flow calibration.
The result is a robust, easy to assemble flow sensor element with an exceptionally low level of
sensitivity to contamination, outstanding reproducibility of the sensor characteristics – a criterion for
cost-effective single-point calibration – and a wide measurement range. The element is ideal both for
measurements in the low flow range from 0 – 2 m/sec, and for air conditioning technology applications
1/4
for measurements up to 20 m/sec. The extremely fast response time, low angle-dependence and the
compact design are further highlights of the new sensor element. Market launch is planned for the end
of 2013.
Transmitters for industrial applications
E+E Elektronik recently expanded its range of industrial transmitters with the EE300Ex, a new,
intrinsically safe humidity / temperature transmitter. The device conforms to the ATEX Directives for
intrinsically safe equipment and can be mounted directly in explosion hazard areas in zones 0 / 20.
The tried and tested E+E humidity sensor guarantees precise, long-term stability measurements up to
180°C and 300 bar pressure. Thanks to its easy-to-clean stainless steel housing, the EE300Ex is ideal
for use in the pharmaceutical and chemicals industry.
The company is also focussing heavily in the field of compressed air monitoring. The thermal
flowmeters from E+E Elektronik record the mass flow of compressed air and industrial gases,
independently of pressure and temperature. Different versions (EE771, EE772, EE776) permit the use
for pipe diameters between DN15 and DN300, and an operating pressure of up to 40 bar. Simple and
rapid mounting - with replaceable valves with no power interruptions at all necessary - facilitates
installation into existing systems as well. For example, the consumption of compressed air, nitrogen,
helium, CO2 or oxygen can be measured. A dewpoint sensor can also be installed in one and the
same mounting valve.
Moisture in oil transmitters from E+E Elektronik permit the precise determination and permanent
online monitoring of the moisture content in lubrication and insulating oils of machines or transformers.
This means that maintenance work can be carried out promptly and according to need. Expensive
repairs and long standstill times are avoided. EE36 devices are certified in line with the Germanischer
Lloyd guidelines (GL) and are thus suitable for use in the maritime sector. E+E moisture in oil meters
are also available in a compact version or as mobile hand-held devices.
Transmitters for HVAC / building technology
For the HVAC sector in particular, E+E Elektronik offers a comprehensive product range for
humidity/temperature, CO2 and air flow. This range is being expanded further with the new EE160
humidity / temperature transmitter. With protection rating IP65, the EE160 housing provides
maximum possible protection against contamination or condensation. The transmitters are available in
wall-mounted or duct-mounted designs and with current, voltage, BACnet or Modbus RTU outputs.
