Frequently asked questions
Sisgeo digital instruments can operate in two powering modes: TIMED or ALWAYS-ON (for more information see F.A.Q.#094.A string of mixed instruments consisting of TIMED gauges and ALWAYS-ON gauges cannot work.The first thing to do is therefore to check that ALL connected instruments in your array are set to TIMED mode.You can check the powering mode […]

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.

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 […]

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).

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.
