FAQ#094 – Which are the available powering modes for SISGEO digital sensors?
All SISGEO digital gauges can be settled in two different powering mode: The STANDARD powering mode is ALWAYS ON, so unless otherwise requested by the Customer, the sensors are settled as default in ALWAYS ON.
FAQ#087 – Could the IPI, BH Profile and DEX probes have problems in frozen water?
Sisgeo suggest that frozen water within the inclinometer casings is to be avoided due to following reasons: – Ice within the casing will affect functionality of the systems by blocking the individual probes;– Mechanical damages can occur to the probes, but also to the inclinometer casing due to the expansion of frozen water In any […]
FAQ#081 – Which is the maximum cable length for DEX and DEX-S probes?
The maximum instrument cable length from DEX probe to datalogger is 200 m. If the automatic data acquisition system includes distributed external multiplexer box, the maximum cable length is 200m from DEX probe to multiplexer box plus 200m from multiplexer box to OMNIAlog (in total 400m).
FAQ#075 – What parameters are saved in SISGEO digital sensors? What information must the Customer provide when ordering?
All SISGEO digital sensors (e.g. IPI, BH Profile, MD Profile, LT Inclibus, Tilt-meter, RDS, H-Level, etc.) use the Modbus communication protocol over RS-485 serial. SISGEO digital sensors are connected to each other with a single signal cable. The parameters that are configured at the factory for each digital sensor are as follows: Upon confirmation of […]

FAQ#031 – Is the DEX system suitable for in-place applications?
DEX system has been designed for automatic soil settlement monitoring (vertical movement) in unattended location. DEX system consists of a string of DEX probes installed in borehole within a ABS inclinometer casing. DEX-S, the combined inclinometer-settlement probe, provides both horizontal movements (X, Y-axis) and vertical settlement (Z-axis) for 3-D borehole automatic profile monitoring.

Chuquicamata Mine (Codelco), Chile
Chuquicamata is an opencast copper mine, where a relatively poor copper ore is mined in impressive huge amounts. Modern mining and smelting technology allows the usage of such depostits at unrivaled low costs. The ore contains only between 1,13% and 1,18% metals, most of it copper, but also molybdenum and selenium in a very low […]
