continuous level sensor binmaster level smartbob aoBinMaster Level Controls’ SmartBob AO level sensor features an integrated 4-20 mA analog output to a PLC for monitoring bin-level measurement data. A push-button user interface built into the sensor’s circuitry is used to configure the settings for each device. The sensor features 2 user-configurable relays. The user selects any 2 of 4 different relay options in any combination including measurement status, high-level alarm, low-level alarm or error alarm (e.g., the sensor did not take a measurement). The unit includes the output of a 22 mA error signal if the device should encounter a “stuck-top” or “stuck-bottom” condition and a soft start feature that reduces wear on the motor.
