This kind of piezometer Type PP4 RS in the heavy-duty model with an extra ring filter made of sintered metal. The piezoresistice piezometer is used to monitor pore-water pressures. The pressure sensor of heavy-duty piezometer is encapsulated in a waterproof housing made of stainless steel with a diameter of 40 mm and a length of 230 mm. Filter area: 57cm2

Model with Hydraulic Pressure Pad and Pressure Sensor

The electric stress sensor with hydraulic pressure pad and pressure sensor is used for measurements

  • f earth pressure. The pressure pad connected to an electric tranducer is filled with a hydraulic fluid

in a closed system. When loading the pressure pad, the arising hydraulic pressure is transferred to the diaphragm of the electric tranducer and converted into a stress proportional to the loading.

FIBER OPTIC – GESO DATA S

Distributed Temperature Sensing (DTS) The product being developed by GEOS are basen on the fiber optic Distributed Temperature Sensig Technology (DTS). This technology provides temperature readings along the length

  • f an optical fibre with a high temperature resolution as well as a high spatial resolution.

The temperature is measured simultaneously at regular intervals of normally 1 meter over the whole length of the fibre; the temperaature over each metre being averaged.
