Geoflex Loggers; Sensor Connection - SLOPE INDICATOR GTecLink Manual

3.2 GeoFlex Dataloggers
3.2.1 Sensor Connection
LS-G6-DIG data logger supports different sensor models by default (RS485 port):
●
DGSI GeoFlex In-Place Inclinometers

●
Geosense Inclinometer
●
RST inclinometer
●
Sisgeo inclinometer
●
MDT's Multi-Point Borehole extensometer (MPBX)
The GeoFlex datalogger can power and read 10 GeoFlex sensors with the standard configuration
(57801705). The GeoFlex datalogger with external power (57801700) can power and read 50 GeoFlex sensors.
For other sensors, DGSI ensures that up to 30 Geosense/RST inclinometers
can be safely powered by the data logger. For the Sisgeo inclinometer, 15 can be powered
up to 60 sensors may be read and transmitted by the data logger. An external 12 V battery should be
connected if more sensors are to be supplied. In this case, contact DGSI.
The GeoFlex datalogger can also read MDT's Multi-Point Borehole extensometer (MPBX) up to six anchor
points connected to a SMART Link-485 digital interface. It is also possible to read up to five MPBX with six
anchors each connected to one SMART Link-485 through a multiplexer.
Wiring is indicated in the RS485 port of the data logger. The data logger must be placed at HALF to read the
inclinometers. For the connection of digital data loggers at SDI ports, wiring must be checked at the sensor
specifications.
Note: Always remove plastic protection from Half/Full switch as it can cause erratic behavior on node.
Tested with a chain of 8 Sisgeo inclinometers.
