ADR-50DU Advanced Ultrasonic Closure Monitors

The ADR-50DU is the newest to our ADR-50D lines.  It has an ultrasonic sensor that will identify and reject all common mechanical and process related defects such as missing & misapplied lids, low/high internal pressure or vacuum deviations, knocked down flanges, "leakers", "swells", etc.

Is a non-contact detector that does not use the Reference Strip (Ware Strip). Accurate on-line inspection and control of container vacuum, pressure and leak defects on can, glass, PET and composite container lines. The ADR-50DU Universal Closure Monitors provide automated operation on-line data analysis and exceptional performance accuracy. Standard systems resolve all container inspection and control requirements for closures of 2 to 6-1/4 ( 50mm to 165mm ) inches in diameter. High speed can or bottle line lane selector for simple single container removal to pull tab or two piece random can orienting. Can be used on metallic and non-metallic lids. The ADR-50DU is ideal for low acid canning where swelling lids could be a problem.
