Limfjordstunnelen – Tunnel monitoring
Limfjordstunnelen is a Danish motorway tunnel which connects the highway in eastern Aalborg with the highway east of Nørresundby. Opened 6 May 1969, it was the country’s first motorway tunnel. The tunnel measures 582 metres (1,909 ft) in length, and 27.4 metres (90 ft) in width. Limfjordstunnelen comprises a 6-lane motorway, which is part of the E45. The tunnel consists of […]
Neckartal Dam project
In March 2020 the huge dam of Neckartal was inaugurated in Namibia. This dam is fundamental to bring water to the Namibian desert and irrigate 5 thousand hectares of land, stimulating the agriculture and creating employment.This work, realized with the RCC technology (Roller-Compacted Concrete), is the biggest dam of Namibia: 80m high, 518 long and […]
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.
“La Linea” Road Pass, Colombia
Tunnel “La Linea”, recently inaugurated, connects Colombia from the south-west to the center of the country, from Portal Bermellón in Cajamarca – Tolima, to Portal Galicia in Calarcá – Quindío. With a length of more than 8 kilometers, it is the longest road tunnel in the Americas. The road has two motorways exits and 13,4 […]

Warsaw Metro Project – Line 2
The 6.5 km east-west route links Rondo Daszyńskiego and Dworzec Wileński includes seven stations and an 870 m tunnel under the Wisła River. The civil works began late in 2010 and became operative in March 2015. In 2016 the works for the extension toward east and west of the second line started, estimated schedule of […]
Vibrating Wire Deformation Meters
Reference products codes: D233, LBSG VW deformation meters (also named LBSG – Long Base Strain Gauges) are mainly designed to be enbedded into concrete or RCC dams in order to measure expansion of induced joints. Deformation meter consists of a vibrating wire displacement transducer housed into a PVC tube having a steel flange on each […]
Embedment Jointmeters
Reference products codes: D314 The embedment jointmeter allows to detect the movements between two anchors. It is suitable to be merged in concrete grouting, placing it across expansion joints, as usually occur in concrete dam. A thermistor allows temperature measurement for temperature compensation, if needed. It consists in two anchors, a vibrating wire displacement tranducer […]
Wire Crackmeters
Reference products codes: D241 Wire crackmeter allows to monitor the changes in the distance between two anchor points located up to 30 m apart. Typical applications include measurements of large displacement associated with landslides, monitoring of rock-masses, mansonry cracks and surveying of earth faults. The wire crackmeter consists of a stainless steel transducer box which […]
Wire Deformeters
Reference products codes: D313F, D314F Wire deformometers allows to monitor the changes in the distance between two anchor points. Typical applications include measurements of small cracks, convergence monitoring in tunnel and structural deformations. The USB wire deformometer consist of an aluminium logger and transducer box with a tensioned steel wire having 80mm stroke. Electrical deformometer, available […]
Ojo de Agua Hydroelectric project

The project will generate 109 GWh/year with an installed capacity of 22.5 MW, a discharge of 6.0 m³/s and a gross head of 418 m.The project consists of […]
Electrical Crackmeters and Jointmeters
Reference products codes: D313, D313S Electrical and vibrating wire crackmeters (jointmeters) are intended to monitor movement across surface cracks and joints in concrete structures or rock. The instrument assembly includes sensor housing and target, both parts are equipped with screw anchors. Typically the anchors are bolted on the opposite sides of the joint (crack). The […]
