For single unit applications the Model 4060 LIW Rate Controller is utilized.  This control takes 15 samples from the scale per second and makes corrective speed changes in the hundredths of a second to maintain the desired output rate.   For optimal accuracy, the unit features a processor, which provides 1:1,048,576 counts of resolution and features vibration rejection technology, which intelligently deciphers true weight data – all contributing to excellent system accuracy.

The HI 4060 loss-in-weight rate controller features:

• Automatic closed loop control: continuously adjusts the feeder to deliver the desired feed rate
• True five-point automatic rate calibration: produces high feed accuracy for a wide range of feed rates
• Multiple configuration storage: stores hundreds of different system configurations
• Automatic feeder refill: starts and stops refilling without interrupting the feeding of material
• Convenient manual mode: allows manual speed control, with switch to automatic control at the touch of a button
• Various alarms, including rate tolerance and disturbance
• Embedded web server for remote access
• Communications: optional DeviceNet, EtherNet/IP, Remote I/O, Profibus, Modbus TCP/IP, and Analog
