Operating Conditions; Installation Guidelines - Evikon PluraSens E2658 Series User Manual

E2658-N2O

Operating conditions

The device should be used in a basic electromagnetic environment, where the latter is
defined in EN 61326-1. Avoid strong mechanical shock and vibrations. Although E2658
series devices are suitable for use in the presence of flammable dust, special precautions
should be taken when operating in a dusty environment. Dust may block the porous filter of
the sensor and compromise the results of the measurement. The detector should be
inspected regularly if used in a dusty atmosphere. Keep the instrument away from direct
sunlight. A sudden temperature or humidity change might affect the sensitivity of the
sensor. Make sure that installation and maintenance are performed in an explosion safe
atmosphere.

Installation guidelines

Before proceeding with the installation it is mandatory to read the Safety requirements
section and make sure to comply with all listed instructions. Installation standards EN
60079-29-2 and EN 45544-4 are also recommended for further instructions and related
information about the installation. During the installation of the detector-transmitter the
following points must be considered:
Application (air quality control or leakage detection.)
●
● Properties of the space under investigation (room geometry, direction, and
velocity of airflows, etc.),
● Nitrous oxide is heavier than air. The recommended location is close to or below
the potential leakage source.
● The device should be accessible for maintenance and repair.
The aforementioned conditions above will affect the coverage area of the device. however,
the coverage area for a detector-transmitter is usually between 2.5 to 5 meters radius.
For early leakage detection install the sensor as close as possible to the potential leakage
sources (flanges, valves, pressure reducers, pumps, etc.), taking into consideration other
points listed above.
For general area monitoring without definite leakage sources, the detectors should be
distributed evenly in the room.
For personal safety control, the detectors are installed in the breathing zone (at the height
of the head of people or animals). The recommended sensor position is vertical, pointing
downwards.
