ETL Group - New Range Of Meteorological Measurement Systems


Strict Standards: Only variables should be passed by reference in /home/defensef/public_html/components/com_zone/handleHTML.php on line 623
ETL Group
: 01 June, 2007  (Company News)
The ETL group announce the availability of a new range of Meteorological Measurement Systems, which are designed to provide high accuracy data such as atmospheric pressure and relative humidity measurements from barometric pressure, temperature and relative humidity sensors.
The range comprises of two models which are designated the MET3 and the MET3A. Both have a pressure resolution of more than 1 microbar with a total accuracy of 0.09 hPa over the extended barometric range of 620 to 1100 hPa.Temperature resolution is 0.01 degree C. the fan aspirated MET3A has a total temperature accuracy of 0.1 degree C over the full temperature range of -50 to+60 degrees C. Relative humidity performance is more than 2% at 25 degrees C, and humidity recovery time for the MET3A after 100% water saturation is less than 2 minutes.

These fully integrated systems are housed in environmental enclosures for stand alone, indoor or outdoor mounting. Installation hardware and software are included, with optional interface cabling for easy integration. The MET3A radiation shield protects the temperature and humidity sensors from precipitation and solar radiation. A high performance tuned barometric pressure port reduces dynamic pressure errors caused by wind.

Microprocessor-based electronics provide fully temperature compensated and linearised outputs via a two way RS-232 interface. The serial interface allows complete remote configuration and control of all operating parameters including resolution, sample rates, choice of engineering units, integration time and sampling commands. Individual measurement parameters or a unified data word with all sensor outputs are easily interfaced with computer systems, GPS receivers, and data loggers.

These innovative systems are ideal for GPS Meteorology (Precipitable Water Vapour), Crustal Observation, Tectonic Research and Weather and Climate Research Studies. Other areas are Surface and Maritime Weather Observation and Ground based Altimeter Setting Indicators.

These versatile products have applications in Metrology, Aerospace, Meteorology, Oceanography, Process Control and Laboratories.
