ENC 8/10, ENC 10/12, ENC 12/14,
ENC 14/16, ENC 16/18 and
AM-ENC/ENCT Enclosures
This manual describes Campbell Scientific’s ENC 8/10, ENC 10/12, ENC 12/14, ENC 14/16,
ENC 16/18 and AM-ENC/ENCT enclosures. This information should be used in conjunction
with other information given in the datalogger or weather station manuals.
1. Description
These enclosures are made of white fibreglass-reinforced polyester. The colour of
the enclosure and the environmental sealing mean that there is no need for a
conventional radiation/rain shield. The enclosures can be wall mounted as
supplied, or pole mounted using the optional enclosure mounting brackets. The
door is fitted with a catch which can accept a padlock if required.
The enclosure is fitted with an anodised aluminium chassis plate which is punched
with an array of holes. The holes accept plastic inserts for accepting screws for the
attachment of power supplies, dataloggers and peripherals. These plastic fittings
can easily be inserted by hand allowing the rapid mounting of components inside
the enclosure.
A small cable gland is fitted to the base of the enclosure and a venting plug is
fitted to this gland. The plug allows pressure equalisation between the inside and
outside of the enclosure (which is required when using barometric or gauge
pressure transducers) and also prevents pressure build-up in the enclosure in the
event of a system failure when charging lead-acid batteries. A blanking plug is
supplied which can replace the porous venting plug, if this is not required.
We recommend that sealed environmental connectors are used for the entry of
sensor leads into the enclosure. However, a large cable gland is also fitted which
can be used for the direct entry of one or more cables into the enclosure.
An earthing boss is also provided for the connection of an external earth lead.
Internally an earth wire is fitted which should be taken to the main earth point
inside the enclosure (normally on the datalogger).
Four bags of desiccant are supplied with the enclosure and are used to maintain a
dry atmosphere inside the enclosure.
2. Installing Components in the Enclosure
When the enclosure is bought as a configured system, the components will be pre-
fitted. If they are not fitted the convention is that the power supply (normally a
PS100E) is mounted in the top of the enclosure (this is the end opposite to that
where the cable glands are fitted). The datalogger is fitted next from the top and
then any peripherals at the bottom.
To fit the components, first work out exactly which holes are to be used and then
push the nylon inserts into the holes in the chassis plate. A 3.5mm or 6-32 thread
screw can then be screwed into the insert. Normally enough inserts and screws are
supplied with each datalogger or enclosure to cater for all peripherals.
