Automatic Test Weight Lift & Storage Mechanism For "M" Type Weigh Belts

More and more weigh feeders are being used in conjunction with statistical process control where performance records are routinely generated and delivered with the product as required by a customer’s quality assurance program. Such a record should contain a “validation of scale calibration” step to be truly meaningful as a quality assurance tool. Thayer’s automatic test weight mechanism provides a means for automatically applying a known test weight and going through a calibration sequence on computer or push-button demand to check scale calibration. A “foolproof” self-checking software algorithm in the feeder control instrumentation prevents erroneous calibration.

Calibration is fast, accurate and reliable. The Thayer Scale test weight calibration method has proven accurate and reliable over decades of in-plant use. Unlike material sampling, it is always clean, fast and safe. Unlike electronic signal stimulation scale loading, it actually tests the performance of critical electro-mechanical components. The Thayer Automated Test Weight Placement Assembly now makes calibration even easier and more exact.

THAYER ATWL Features:

• Auto Zero Calibration Check
• Auto span calibration Check
• Auto adjustment of zero and span errors.
• History of past calibration results stored in instrument for trending and determination of required calibration interval.
