Belt Scale System with Speed Sensor is designed for general in-plant conveyor-belt weighing applications in the most demanding industrial environments. The Belt Scale System consists of a compact weigh bridge with two load cells mounted on a steel frame, speed sensor and an integrator which processes the signal from the belt scale. The Belt Scale System is equipped with an adjustable single alarm for high or low flow rates and a fully automated zero calibration facility. Belt Scale System with Speed Sensor can be configured with security locking to prevent accidental interference or unauthorized access.
