BinDisc

The handy, affordable BinDisc interface simplifies sensor setup and configuration. Easily mounted in locations that are ground or vehicle accessible or integrated into the sensor housing, the interface provides continuous, at-a-glace operational status of the sensor and aids in on-site system diagnosis. Data can also be sent to a PLC in a control system.
