2 Février 2012New Multi-level Piezometer released
The multi-level vibrating wire piezometer is perfect for measuring pore pressures at various depths beneath a single surface location. It allows for quick and reliable installations because multiple piezometers are connected to a single communication cable, which is in turn connected to the data acquisition system or readout. This configuration eliminates complicated and time consuming and, therefore, costly process for installing multiple single sensors in the same borehole. This simplified installation not only reduces installation time but also minimizes the potential for hydraulic communication between sensors that might lead to erratic readings. A typical installation of the multi-level piezometer utilizes a direct grouting installation so that only the multi-level piezometer string and a grout injection tube are needed to complete the installation. Once the grout has hardened, the piezometers are isolated from one another, allowing precise measurements of pore water pressure changes at various depths.
The multi-level piezometers incorporate the same standard features included in our single PW-series vibrating wire piezometers. The main function of this multi-level piezometer is to measure pore water pressure beneath the ground surface. It provides significant advantages in terms of time, resources and cost reduction related to installation, while providing quick and reliable reading at various depths. The multi-level piezometer allows the customer to define sensor spacing along the readout cable providing precise depth control based on site specific requirements. Junctions between each piezometer and the main cable are reinforced using epoxy resin for a waterproof and durable seal. The time proven design of the PW-series sensors allows them to be tied to the multi-level piezometer core cable and provide very reliable long-term performance. The sensor wire is fabricated using proven methods for ensuring an exceptional long-term stability. It is isolated in a vacuum sealed chamber to protect against corrosion. A gas filled spark gap integrated into each sensor protects against electromagnetic surges and radio frequency interference. A triple watertight barrier is installed at the cable end to prevent water infiltration to the sensor core. To this day, thousands of PW sensors have been installed and operate throughout the world.
21 Décembre 2011Holiday Greetings

31 Octobre 2011New Convex-D Convergence meter released
The Roctest Group has just released its new CONVEX-D digital tape extensometer, which quickly and accurately measures relative distance changes between two reference points in any orientation. The CONVEX-D is a lightweight and dust proof portable device that has a robust and reliable construction. It is also an essential measuring tool that can be used to monitor applications like mine roof sags, tunnel convergence, dam slope stability and sheet piling deformation. The CONVEX-D is also a "design as you monitor" approach measuring tool, and is compliant with the New Austrian Tunneling Method (NATM). This new instrument incorporates several improved features in comparison to older analogue CONVEX and other convergence measuring instruments available on the market. Among these improvements, which have been designed keeping in mind easier handling for the end-user, you will find: a new pivoting hook that positively locks on tape, a rugged rotary protection drum that allows quick access to function buttons of the new added digital display, and an anti-backlash mechanism to ensure a reliable and a repeatable accuracy for long-term repetability and durability. The CONVEX-D is offered in two versions in order to meet customer needs. There is the anodized aluminum construction offered as the standard model and an even more robust construction, all stainless-steel, for coal mines or other types of harsh environments.
For more information about this product, contact us to discuss how this product could be used for your specific needs and applications.

6 Septembre 2011Nova Metrix LLC conclut l’acquisition de Sensornet Ltée
Le 31 août dernier, Nova Metrix LLC (Nova Metrix) a annoncé avoir fait l’acquisition de Sensornet Ltée (Sensornet), entreprise établie à Elstree, Hertfordshire, au Royaume-Uni. Sensornet fournit des systèmes de solutions de surveillance les plus évolués offerts sur le marché, reposant sur des systèmes de surveillance de la température et de la contrainte distribuées en temps réel. « Avec ce nouvel atout au portefolio de Nova Metrix, nous serons désormais en mesure d’accroître notre offre de produits et services dans le domaine de la surveillance, tout en renforçant et en consolidant les technologies déjà existantes que proposent Roctest Ltée et Durham Geo Enterprises inc. », a déclaré Jim Barbookles, président et chef de la direction de Nova Metrix. Toutefois, l’activité reliée aux puits de pétrole et de gaz de Sensornet demeure sous la direction de son ancien propriétaire, Tendeka.

31 Mai 2011Geomation Solar Panels and Radio Communication Datasheets
The Roctest Group has just released new Geomation datasheets. These new datasheets are mainly for solar panel and radio communication parts. Since Geomation’s products are design for autonomous and stand-alone applications, these features (power and communication) are critical, and therefore require specific parts in order to be compatible with Geomation line of products.

26 Mai 201110,000th SOFO sensor produced at SMARTEC
SMARTEC is proud to announce the production of its 10,000th SOFO fiber optic sensor. Originally introduced in 1996, SOFO and MuST deformation sensors have been used in hundreds of projects to monitor strain and displacement in bridges, buildings, tunnels and many other types of structures. These large numbers of applications and sensors produced have clearly demonstrated the reliability performance of the SOFO technology. Sensors installed 15 years ago are still active today and are showing no sign of ageing or drift.
By a curious twist of fate, the 10’000th sensor is being delivered to EPFL (Swiss Federal Institute of Technology), where the SOFO system was originally developed in the early 1990s.
