Fuel terminal monitoring

Supply of instrumentation for the monitoring of fuel terminal tanks in the city of Cuenca, Ecuador. The scope includes the monitoring of the settlements of structures through H-Level settlement cells and tiltmeters. The settlements and horizontal movements of the ground will be evaluated through IPI inclinometer probes and DEX S probes.

Messbalken-Tiltmeter

Codes der Referenzprodukte: S700, S7BM Tilt Beam (TB) sensors can be used both in chain to measure a continuous displacement or in stand alone application to measure the tilt-displacement between two point (ends of the beam). As all Sisgeo’s MEMS tilt sensor, they use the latest MEMS technology that grant great performance and low temperature dependance. […]

Rome Underground – Line C – Italy

Rome metro Line C runs through the city from North-West (Della Vittoria district) to the eastern suburb and is extending beyond the Grande Raccordo Anulare.Line C has a full-run of 25,6 km and 30 stations, passing through the old town centre.The Route will be characterised by the green colour. The interchanges with the other metro […]

Bangkok Blue Line Extension Project, Contract 2 – Thailand

The MRT (Metropolitan Rapid Transit) Blue Line is being extended.The extension is expected to be completed in 2017 and by then the Blue Line will become a loop line around the centre of Bangkok, with the part on the western side of the Chao Praya River mainly being an elevated system and the other half […]

FAQ#116 – How do I configure a WR-Log digital node to read RS485 Sisgeo TIMED sensors?

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 […]

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#076 – Why it is necessary add a termination resistor to the last digitized sensor of each RS-485 chain?

All SISGEO digitized instruments (IPIs, Tiltmeters, H-Level…) use the RS-485 serial communication protocol The RS485 protocol contemplate a termination resistor. The recommended chain connection is point-to-point (multidropped) nodes as a bus mode (line). Star, ring or multiply network connection are not recommended. SISGEO dataloggers has already a termination resistor assembled (typically 120Ω). On the opposite […]

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#074 – Which kind of datalogger is necessary to read a SISGEO digital sensors?

The sensors are read connecting the end cable to a Modbus Master unit (i.e. OMNIAlog or miniOMNIAlog) with RS-485 interface (DCE, Half duplex, no Echo) able to manage communication with SISGEO Modbus RTU communication protocol. SISGEO’s communication protocol is available for the release upon request. The power [W] of power supply must be chosen according […]

FAQ#073 – Which is the maximum number of digitized sensors (RS-485, Modbus), the maximum number of chains and the maximum length of cable in a RS-485 network?

Last update: October 2021 All the SISGEO digitized sensors utilize a RS485 interface with Modbus protocol. 1.The maximum number of digitized sensors in a RS-485 network are 247 (theoretical) 2.The maximum number of digitized sensors chains that is possible to connect to Modbus master unit (as OMNIAlog or miniOMNIAlog) are 4. 3. About the maximum […]
