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.
Clinometri a barra analogici e digitali
Codici di riferimento: S700, S7BM I clinometri a barra vengono utilizzati sia singolarmente per monitorare l’inclinazione relativa tra due punti, sia installati in catena per misurare ad esempio i cedimenti differenziali di un edificio. Come tutti gli strumenti con tecnologia MEMS prodotti da Sisgeo, sono dotati di un sensore di temperaturea a termistore per monitorare […]
Metropolitana di Roma – Linea C
La linea C della metropolitana di Roma, attualmente in costruzione, taglierà la città da nord-ovest, nel quartiere Della Vittoria, alla periferia est estendendosi oltre il Grande Raccordo Anulare per una lunghezza totale di circa 25,6 km e 30 stazioni passando per il centro storico. Sarà contraddistinta dal colore verde. Attualmente sono in costruzione circa 21,5 […]
Estensione Linea Blu, Contratto 2
La Linea Blu della MRT (Metropolitana a Transito Rapido) è in via di ampliamento. L’estensione sarà completata nel 2017 e da quel momento la Linea Blu sarà la linea circolare che viaggia intorno al centro di Bangkok, con una parte sopraelevata lungo la riva occidentale del fiume Chao Praya e una parte prevalentemente sotterranea lungo […]
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 – Which parameters are save into SISGEO digitized sensors?
All SISGEO digital sensors (IPIs, Tilt-meters, RDSs, H-Level etc..) use the serial RS-485 communication protocol.The SISGEO digital sensors are joined through an electrical cable, so only one cable is used to take reading. In agreement with Customer, they are configured in factory for:
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 […]
