Product Description

S52c WEIGH BELT or LOSS-IN-WEIGHT CONTROLLER

The S52c Instrument can be used on most Weigh Belt and Loss-In-Weight Feeder systems to provide continuous control and information about the flow of material to its process by monitoring the load and speed. The weigh system can use either a strain gage or LVDT Load Cell to sense weight; however a variety of sensors can be used to sense the speed.

Weight information on a Weight information is processed as weight per length and speed is processed as unit length per time. Integrated together, this information is processed by the controller portion of the instrument to provide continuous control of the system to match a target flow rate or set-point.

On a Loss-In-Weight application the S52c uses the change in weight of the feeder to determine instantaneous material flow rate and accumulative weight total information. The speed is used to control the feeder when in volumetric control, used during refill and disturbance control integrated together, this information is processed by the controller portion of the instrument to provide continuous control of the system to match a target flow rate or set-point.

All information gathered by the system is then presented both visually on the instrument’s face and through optional communications via a number of field buses.
