The SmartBob AO is a weight and cable-based, stand-alone continuous level sensor featuring direct analogue output. A simple push-button user interface built into the SmartBob AO circuitry is used to configure the bin parameters and assign the functionality of the relays.

As all programming is done within the device, the SmartBob AO eliminates any need for additional operator interface displays or software loaded onto a PC. Once programmed, the parameters for the bin are saved in the non-volatile memory of the SmartBob AO.

The SmartBob AO with built-in 4-20 mA output can easily replace any 4-20 device by simply installing the SmartBob on the top of the bin and wiring the sensor to the existing 4-20 input. When the SmartBob AO takes a measurement, it automatically transmits an updated analogue signal containing the measurement data. The SmartBob AO can be programmed to initiate a measurement utilizing an internal timer to take readings at a predetermined time interval or an external start input can be used to take a measurement immediately, should one be needed. Two configurable relay outputs can be used to alert to measurement status or high, low or error alarms.
