G7 Vibrating Wire Data Logger

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 data logger and enable the connection of more than one MPBX to the node.

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 Laser Tiltmeter can be suitable alternatives.

Total pressure cells at different orientations and piezometers can be connected to a 6-channel Vibrating Wire data logger to interpret the behavior of the paste backfilling and the load on the barricade.

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

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 6-channel data logger.

Connect piezometers and multi-point piezometers from all the major geotechnical sensor manufacturers. Use 1-channel, 2-channel or 6-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.

Monitor the tensional states of concrete tunnel linings using a NATM connected to a Vibrating Wire 6-channel data logger.

Attach vibrating wire strain gauges to the steel arch supported by arc welding them directly to the steel arch to achieve long-term strain measurements of the structural element. Connect the gauges to the Vibrating Wire 6-channel data logger. Additionally, it is possible to embed vibrating wire strain gauges in the shotcrete to measure strains within the tunnel lining.

Crack meters available in the market can be readily connected to a Vibrating Wire 1-channel data logger or the Piconode to monitor movement across surface cracks.

Monitor the pot bearing pressure and displacement through pressure sensors, extensometers or crackmeters. Control the joint expansions and contractions wirelessly connecting these sensors to Analog, Digital or Vibrating Wire data loggers.

Assess the proper functioning of your superficial drainage by connecting a V-notch weir to a Vibrating Wire 1-channel data logger.

Different sensors compatible with Worldsensing data loggers can monitor flow in open channels and seepage collection ditches. For instance, non-contact level sensors using radar or ultrasonic technology can connect to the Analog data logger. Additionally, a vibrating wire weir monitor and a V-notch can measure flow in an open channel using a Vibrating Wire 1-channel data logger. Some of these sensors are also suitable for monitoring tailings pond levels.

Assess the tangential and radial stresses in shotcrete support for underground excavations with pressure cells connected to the Vibrating Wire 6-channel data logger.

Ensure the proper functionality of anchor systems (active and passive) by monitoring in a representative sample the load throughout their lifecycle including the load tests and stressing works. Stream data wirelessly from most of the load cells based on resistive strain gauges available in the market using the Piconode data logger. The 6-channel Vibrating Wire and the Digital data loggers can also be suitable, depending on the type of load cell.
