StreamTech provides, installs and services a broad line of conveyor checkweighers both as integral parts of our shipping and automation systems as also for stand-alone quality control applications.  Below is a sampling of a few of our major checkweigher models.  Please contact us for additional information; we have solved many unique applications beyond what is pictured here.

StreamTech Engineering Conveyor Checkweighers

Small item, high speed conveyor checkweighers that include infeed and/or discharge belt conveyors. This is a premium unit that is capable of direct food contact and tolerant to washdown applications. Tool-less removal of frames and belt. 1″ dia. rollers for smooth transitions for the smallest parts including cookies and other foodstuffs.  The design can be “ganged” for multi-lane applications. Servo driving belts for smooth operatio and high accuracy. As these accuracies, slight air currents can make a big difference so optional wind tunnels are available to maintain performance. Optional items include reject diverters for out-of-tolerance items or used when sorting by weight, stack lights, etc.
