Rate controller

Hardy Instruments’ HI 4060 is a compact, single-feeder, closed-loop rate controller for use in a variety of applications, including auger, belt and vibratory-based feeders, converting them from volumetric to gravimetric.

After supplying excitation to the load sensors and digitising the weight signal, the rate controller provides an analog output to control the feeder speed and adjusts this signal based on the required rate at which the feeder is losing weight.

This rate controller features an embedded web server, true five-point automatic rate calibration, automatic feeder refill, various alarms including rate tolerance and disturbance, and optional DeviceNet, EtherNet/IP, remote I/O, Profibus, Modbus TCP/IP and analog communications. It also includes Hardy’s Waversaver technology to eliminate the effects of surrounding vibration for fast, stable weight display, electronic calibration without test weights, an SD memory module card for fast transfer of configuration data and integrated system diagnostics and troubleshooting.
