St. Moritz, Chesa Corviglia

St. Moritz Brattas-Fallun, Chesa Corviglia, 22 years landslide and structural health monitoring.Located above the northern part of the town of St. Moritz in Switzerland, there is a 600m wide and about 1500m long clastic flow type landslide. At the sides bounded by parallel shear zones and at the lower end constrained, the Brattas-Fullun landslide is […]

Convergence extensometer

Reference products codes: D235 Convergence Extensometers, are rod extensometers allow to monitor the changes in the distance between two anchor points. Typical applications include convergence monitoring in tunnels, caverns, underground mining and structural health monitoring. The convergence Extensometer is based on a long stroke linear potentiometric displacement transducer. It consists of a rigid, light weight telescopic […]

ALACAES Pressure plug instrumentation – Geotechnical monitoring for a research project – Switzerland

ALACAES, an Airlight Energy company, is currently constructing a compressed air energy storage solution that enables large-scale electricity storage. ALACAES’ storage solution will be a valuable solution for grid stabilization and energy balance of the electricity network.This pilot plant in Pollegio, Switzerland, to test the feasibility of its electricity storage solution will exploit an abandoned […]

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 […]
