S52i Weigh Belt & Belt Scale Integrator

THAYER’s S52i is a compact, cost effective belt scale integrator. Advanced microprocessor based technology is used to process both weight and speed signals and output accurate and stable reading of flow rate and totalize weight of bulk solid materials. The S52i integrator is compatible all THAYER non-commercial Belt Scales and Weigh belt scales. As a retrofit, the unit will work with any single or dual load cell based weigh-bridge.

S52i Weigh Belt or Conveyor Belt Integrator

THAYER’s S52i Integrator is a full featured instrument in a single, compact package. It performs the same functions as an instrument costing many times more without sacrificing the accuracy associated with THAYER products. Simplicity of use has always been a very important factor in designing an instrument and the S52i has inherited all the time and labor saving methods THAYER has developed over the years.

The S52i Instrument can be used on most belt conveyor weigh belt systems to provide continuous information about the flow of material to its process by monitoring the load and speed. The weigh system must use a strain gauge to sense weight; however a variety of sensors can be used to sense the speed. Weight information is processed as weight per length and speed is processed as unit length per time. Integrated together, a great deal of information is available about the system, such as: flow rate; accumulated weight (total); belt loading; belt speed; etc.
