Addressable Vibrating Wire Interface | Model 8020-30
The Model 8020-30 Addressable Interface is designed to “daisy-chain” vibrating wire sensors on a single 4-conductor cable, using the Modbus® RTU protocol over an RS-485 connection. It is particularly useful for reducing cable runs in multipoint systems, incremental extensometers, and for applications where many sensor cables might compromise a grout or cement bond, e.g. on a soil nail. The system features state of the art signal conditioning and digital addressing to provide a measuring system comprising of up to 100 sensors along one common cable (the maximum number of sensors is determined by overall cable length and power supply: please contact GEOKON for more information). Readout is achieved with the FPC-2 Field PC, 8600 Series Dataloggers or via a PC application.
