The following pages details how to connect the Campbell Scientific range of data loggers to the VibWire-108 family of vibrating wire sensor interfaces. Any Campbell logger can be used so long as an SDI-12, RS-485 or analogue input ports are available. The switched power supply ports available on some Campbell loggers are ideal for driving the VibWire instruments as they can be powered off between readings to minimise power supply ratings.
Operations
The simplest way to read information from the VibWire instruments into a Campbell logger is to use the SDI-12 serial network. The complete process of reading a signal from a Vibrating wire sensor to the storage within the logger is purely a digital operation. The Campbell logger acts as the SDI-12 Master and the VibWire-108 instruments as SDI-12 slave units. The standard SDI-12 commands shown within Campbell manuals are compatible to reading information from the Keynes Controls product range.
