8960 Series

The Model 8960 Series Digital Vibrating Wire Interfaces expand the capacity of GeoNet Dataloggers, Mesh, Cellular, and Wi-Fi® Multi-Channel and Addressable Loggers by allowing users to add additional sensors to the system. The Model 8960 Series also enables the reading of vibrating wire sensors from Modbus® RTU clients using signal conditioning and digital addressing.

The 4- and 8-channel Digital Vibrating Wire Interfaces are also compatible with Model 4900 Vibrating Wire Load Cells. Multiple load cells and VW sensors can be connected to a single interface, provided that the total number of VW gauges does not exceed the channel capacity of the interface.

The Model 8020-38 Addressable Bus Converter is required to connect addressable sensor strings to personal computers, readouts, dataloggers, and programmable logic controllers. The converter acts as a bridge using the TTL or USB protocols between readers and GEOKON RS-485-enabled sensor strings.
