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 […]
