SmartBob AO Continuous Level Sensor

The SmartBob AO level sensor features an integrated 4-20 mA analog output to a PLC for monitoring bin level measurement data. A simple push-button user interface built into the SmartBob AO circuitry is used to configure the settings for each SmartBob AO. To set up the SmartBob AO, the user opens the device to access the keypad and steps through a series of push-button settings to set the interval timer, units of measure, 4 mA and 20 mA drop distances, maximum drop distance, and the Relay 1 and 2 functions. Once setup is complete, measurement data is sent directly to a PLC, with all settings for the bin saved in the non-volatile memory of the SmartBob AO. The interval timer setting initiates a measurement in pre-determined time intervals such as every two, four or eight hours. When a measurement is needed immediately, an external start input can be used to initiate a measurement on demand. Additionally, an override input feature can be used to turn the measurement feature off, disabling the measurement function. The override feature is useful when filling tanks to avoid covering the SmartBob probe with material or to stop measurements when a bin is undergoing maintenance or cleaning.
