FAQ#111 – Why I cannot read correctly my 4-20mA current loop gauge?
It could be a problem connected to the power supply given by the readout or logger. When the power supply is in the current loop (2-wire gauge) it is necessary to consider the effect of voltage drop across the shunt resistor on the voltage applied to the gauge. For example, suppose a 4-20mA gauge requires […]
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 – ¿Cual es la longitud de cable maxima para la sonda DEX y DEX-S?
La longitud de cable maxima para la sonda dEX al datalogger es 200m. Si el sistema de adquisicion de datos incluye una caja multiplexer externa, la longitud de cable es 200m desde la sonda DEX hasta el multiplexer mas 200 m desde el multiplexer hasta el OMNIALOG (en 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 […]
Egnatia Odos Road – Athens, Greece
Egnatia Motorway was designed to the specifications of the Trans-European road network. Across Epirus and Northern Greece from Igoumenitsa to Evros, Egnatia Motorway is one of the largest road construction projects in Europe, 670 kilometres long and 24.5 metres wide.The realisation of this motorway requires the construction of: 50 road interchanges; 350 entrance / exit […]
FAQ #031 – ¿Es el sistema DEX adecuado para aplicaciones fijas?
El sistema DEX ha sido diseñado para el monitoreo automático de los asentamientos del terreno (movimiento vertical) en lugares desatendidos. El sistema DEX consta de una cadena de sondas DEX instaladas en pozo de sondeo dentro de una carcasa inclinometrica ABS. La sonda DEX-S, la sonda inclinómetro-asentamiento combinado, ofrece ambos movimientos horizontales (X, eje Y) […]
