Automatic Rate Controller for Granular Spreader Systems

The GSC-1000 from Micro-Trak is a low-cost high performance easy-to-use dry rate controller that not only controls product rate, but also has an optional RPM input. Once the spreader constant has been determined by a simple calibration procedure, product density or gate setting can be changed by simply entering calibration and changing the density or gate height; no need to re-calibrate the spreader constant.

Alternately the GSC-1000 can be easily and quickly configured to do non-ground speed based spinner RPM control.
