Derived from postal weight verification research, the patented "Weigh on the Fly" technology enables ultra high speed mass detection in automation applications. The technology can be applied anywhere high speed weighing operation is required.

Closed loop servo technology ­ Precision servo systems are applied to the mass in motion challenge with superior results. Processing through­puts of greater that 1000 ppm are achievable. Ultra high speed ­ Processing to 1000 ppm and beyond using closed loop servo technology.

In­Line Scale ­ The weigh on the fly tech­ nology is depicted in the graphic to the left. In this application, a precision servo drives conveyor rollers to accelerate articles under test. The servo behavior is monitored and processed extracting precision mass measurement.
