Interfaces and Multiplexers

  • Geokon GeoNet

    GeoNet is a low-power, wireless data acquisition network developed to more efficiently collect data from many points. The system consists of a Network Supervisor (8800-2) and up to 100 Single-Channel Sensor Nodes (8800-1). The supervisor controls the network and is the aggregator of all the data collected by the nodes. Sensor Node Multiplexers are available, which expand the capacity at each node to 8 channels, thereby allowing clusters of closely spaced sensors to be added to the system. The system is compatible with all Geokon Vibrating Wire instruments.

  • Piezometer, VW Push-In

    The Model 4500DP has the transducer located inside a housing with an EW drill rod thread and removable pointed nose cone. When threaded onto the end of EW drill rods, the unit can be pushed directly into soft ground with the signal cable located inside the drill rod. This model is ideally suited for use in soft clays and landfills. The piezometer may be recovered at the end of the job.

  • Settlement Sensor, High-Sensitivity System

    High-senstivity settlement system consists of a series of vessels containing liquid level sensors interconnected by a liquid filled tube. A reference vessel is positioned at a stable bench mark, and all other sensors detect differential settlement and heave from that reference. A VW logger is required, with a channel allocated to each sensor. Standard sensor ranges are 100mm, 150mm, 300mm and 600mm.
