2.4.4 ADDITIONAL INFORMATION

Addressable loggers are protected from environmental contaminants by a
rugged IP66 die cast aluminum enclosure. An earth ground terminal is provided
on the exterior of the enclosure to protect against lightning and other large,
transient voltages.

2.5 MESH TILT LOGGER (880X-XX-TLT-NAP)

Tiltmeters are designed for permanent long-term monitoring of changes in tilt of
structures such as dams, embankments, foundation walls, retaining walls,
buildings, and the like.
biaxial tiltmeter loggers contain an integrated tiltmeter sensor, and
GEOKON
communicate with the gateway in the same manner as other loggers.
The two axes of the tiltmeter have a range of ±90°, based on a starting position
of 0°. To achieve the best linearity, mount the tiltmeter so the back of the
enclosure is as close as possible to vertical, and the bottom of the enclosure is
as close as possible to horizontal.
Though designed to send data wirelessly to a gateway, this model also features
a USB connector for transferring data using a USB cable to a PC running Agent
software, the same as with the single-channel loggers.
