Ambient Conditions and Limits for Operation and Storage
Although the Awite gas analysis systems are designed for use under rough conditions, some requirements
concerning the location and environmental conditions should be met in order to obtain a high accuracy of
measurement and to avoid damaging the system.
4.4.1
Ambient Temperature
In the interior of the casing, the temperature can be 15°C higher than the ambient temperature. Therefore,
the ambient temperature for the device must be between5°C to 35°C in order to guarantee an exact
measurement of the sensors and not to damage the electronic components. The analysis systems are
calibrated at 25°C. All detailed specifications refer to this temperature, any deviations that occur under
significantly changed temperature conditions are sensor-related.
CAUTION
The temperature inside the device can be up to 15°C higher than the ambient temperature. Excessively
high temperatures can lead to damage to components and reduce the service life of sensors. Sub-zero
(°C) temperatures can destroy electrochemical sensors. This affects the measuring function and gas
leakage can occur. Install the device in rooms with temperatures b5°C and max. 35°C. The
temperature in the control box must not exceed 50°C . Do not install the device in the hot exhaust air of
cogeneration units.
4.4.2
Ambient humidity
The relative humidity must be kept between 0 and 80% .
4.4.3
Installation height
The gas analysis system can be operated in areas which are located up to 2,000 mabove sea level
(normal height null, NHN).
4.4.4
Humidity and dust
The gas analysis system complies with IP54 protection class and is therefore dust- and splash-proof.
4.4.5
Measuring gas pressure
The pressure in the measuring lines must be at atmospheric pressure ±20 mbar (normal operation).
Pressure outside this range is not allowed because the sensors may be damaged and measured values
