1.4 EMC - Electro Magnetic Compatibility
EMC is the electromagnetic interaction of electrical and electronic equipment with other
electrical and electronic equipment. All electronic devices have the potential to emit and be
affected by electromagnetic fields. With the reduction in size of electrical components and
the ever increasing amount of electrical & electronic devices such as mobile phones, two-
way radios, safety control systems, signalling, generators, welding equipment, power cables
etc in all environments, especially construction sites, there is a huge potential for devices to
interfere with each other.
Geosense® G8 PLUS has been designed and tested for EMC under the relevant CE
marking directives to comply with the relevant industrial standard. This ensures correct
operation under the harshest of site conditions.
Cables attached to a Geosense® G8 Data Logger Systems should have adequate
shielding to minimise the affects of electrical noise (EMI) and have the correct functional
earth.
FAILURE TO PROVIDE SUITABLY SCREENED CABLES &
TOGETHER WITH EMC GLANDS COULD RESULT IN INCORRECT
OPERATION OF THE EQUIPMENT
ENSURE THERE IS SUITABLE FUNCTIONAL EARTHING TO ENSURE

4.3 Inspection
It is important to check all the equipment in the shipment as soon as possible after
taking delivery and well before installation is to be carried out. Check that all the
components detailed on the documents are included in the shipment. Check that the
equipment has not been physically damaged.
4.4 Storage
Geosense®G8 PLUS contains electronics and whilst they are designed for outside
use and mounted within a waterproof (IP66) enclosure the internal circuit board can
be affected by excessive moisture, dust and temperature. When not in use they
should be stored in a cool, dry location with the cabinet door closed .
Most units have a sealed battery fitted and therefore this should be disconnected if
not in use to avoid discharging.
4.0 DELIVERY
This section should be read by all users of Geosense® G8 PLUS.
4.2 Handling
Geosense®G8 PLUS is a precision measuring instruments. They and their
associated equipment should always be handled with care during transportation,
storage and installation.
Once the shipment has been inspected ( see below ), it is recommended that the
Geosense® G8 PLUS remain in its original packaging for storage or transportation.
Cable should also be handled with care. Do not allow it to be damaged by sharp
edges, rocks for example, and do not exert force on the cable as this my damage the
internal conductors and could render the installation useless.
4.1 Packaging
Geosense® G8 PLUS is packed for transportation to site. Packaging is suitably
robust to allow normal handling by transportation companies. Inappropriate handling
techniques may cause damage to the packaging and the enclosed equipment. The
packaging should be carefully inspected upon delivery and any damage MUST be
reported to both the transportation company and Geosense® .

15
ELECTRICAL NOISE (EMI)
Vibrating wire instruments can be affected by electrical noise which typically comes from
power lines, generators, motors, transformers and arc welders.
Typically “spikes” in the data will be observed and the cause can often be identified by
looking at the time when this interference occurs e.g. starting a welder on site.
One benefit of vibrating wire sensors is that when the readings are affected they are very
evident and do not have any long term detrimental effect on the sensor itself.
