Ituango Hydroelectric project

The 2.400MW Ituango hydroelectric project will be the largest hydropower plant in Colombia. The plant is being built on the banks of Cauca River. The project is located in the northwestern region of Antioquia, about 170km north of the Colombian city of Medellin. The project is a part of the initiative undertaken to exploit the […]

Grand Paris Express

Le Grand Paris Express est le plus grand projet urbain en Europe avec la construction de 200 km de lignes automatiques, soit autant que le métro actuel, et 68 gares. Les quatre nouvelles lignes du Grand Paris Express (15, 16, 17 et 18), ainsi que la ligne 14 prolongée au nord et au sud, seront […]

MEXID – MPBX miniaturisé

Codes de référence: D2MX, D221BM Les extensomètres MEXID sont utilisés pour surveiller les déplacements de points de mesure situés en profondeur dans le sol ou la roche, par rapport à la tête de l’instrument. Le principal atout de MEXID réside dans le diamètre réduit du forage nécessaire, de seulement 50 mm (avant-trou de 75 mm […]

Ulu Jelai Hydroelectric Project, Malaysia

The Project will involve the construction of an accumulation reservoir (Susu Reservoir) with two main water intakes, Telom Intake and Lemoi Intake, located upstream of Susu reservoir. The main part of the project is the construction of the Susu dam on the Bertram River, more than 80 m high and entirely built using the advanced […]

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#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 […]

Chuquicamata Mine (Codelco), Chile

Chuquicamata is an opencast copper mine, where a relatively poor copper ore is mined in impressive huge amounts. Modern mining and smelting technology allows the usage of such depostits at unrivaled low costs. The ore contains only between 1,13% and 1,18% metals, most of it copper, but also molybdenum and selenium in a very low […]
