Geotechnical monitoring

In-place inclinometers are positioned at fixed locations in the inclinometer borehole allowing continuous monitoring. Connect Shape Arrays and IPIs and wirelessly transmit data using the Digital Data Logger or the broadband ThreadX3 for longer chains.

Up to 200 segments of Shape Array using the Digital Logger and up to 300 segments using the ThreadX3.

Leverage compatibility with all major manufacturers of multi-point extensometers (MPBX) and in-place extensometers (IPX). Connect any vibrating wire, potentiometer, or analog displacement sensors installed in the head of the extensometer to the appropriate data logger. Digital MPBXs allow for reading more points with a single digital logger and enable the connection of more than one MPBX to the node.

If higher spatial resolution is needed, a chain of in-place extensometers can be installed in the borehole and connected to a digital logger.

Connect piezometers and multi-point piezometers from all the major geotechnical sensor manufacturers. Use 1-channel or 5-channel Vibrating Wire data loggers to transmit data from any number of sensor configurations. Water level sensors can be connected through Analog or Digital Data Loggers.

Detect slope movements by monitoring tension cracks across landslides using a displacement sensor compatible with Worldsensing’s Analog or Vibrating Wire data logger. For situations with large movements anticipated, wireline extensometers, draw wire sensors, or the LaserTilt90 can be suitable alternatives.

Total pressure cells at different orientations and piezometers can be connected to a 5-channel Vibrating Wire data logger to interpret the behavior of the paste backfilling and the load on the barricade.

Assess soil water tension and moisture with a tensiometer and a granular matrix sensor both connected to an Analog Data Logger. Additionally, measure volumetric water content with a soil moisture sensor connected to a Piconode. You can also connect the Digital Logger to one or a chain of digital tensiometers.

The Digital Logger can be utilized to read and transmit the 3-D stress measurements from HID cells via a digital converter.

Measure total pressure (effective stress and pore water pressure) within embankments -such as tailings dams- and fills to determine its distribution and magnitude. Pressure cells can also be used to measure at the interface between soil and structures. Assess the total pressure measurements with pressure cells connected to the Vibrating Wire 5-channel data logger.
