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 sensor circuitry is used to configure the settings that include interval timer, units of measure, 4 mA and 20 mA drop distances, maximum drop distance, and the Relay 1 and 2 functions. The sensor features two relays that are configurable by the user. Other benefits include the output of a 22 mA error signal if it should encounter a stuck top or stuck bottom condition and a soft start feature that reduces wear on the motor. BinMaster.
