The Electro-Mechanical Silo Pilot Level Transmitters are one of the first technology introduced for continuous level measurement and is still widely accepted by lot of customers because of its rugged design and easy maintenance and repair. A very unique application solution provided by our Silo Pilot device is the measurement of solids submerged within liquids.

The SmartBob AO with built-in 4-20 mA output and integrated keypad 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 analog signal containing the measurement data to a PLC. 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.

  • Operations that prefer direct 4-20 mA analog output versus using the C-100 console or Binventory software

  • Rugged, simple, and dependable inventory measurement system for solid, liquid and slurry materials in vessels up to 180 feet

  • Works in dusty and very demanding applications

  • Vendor-managed inventory

  • Plastics, chemicals, coal, concrete, food ingredients, pharmaceuticals, feed/grain, aggregates, and many other materials

  • Detect Solids Submerged within liquids
