What weighing technology suppliers provide

Suppliers in this category cover mass measurement in the production line rather than in the laboratory. The scope includes strain-gauge and electromagnetic force restoration load cells, platform and silo weighing modules, dynamic checkweighers that verify every pack at line speed, multihead weighers that combine portions to a target weight, and gravimetric dosing and batching systems for bulk solids and liquids. Many suppliers combine weighing with metal detection or X-ray inspection in a single end-of-line unit and provide the data interfaces for batch records. Core competence lies in holding accuracy against vibration, air movement, and temperature drift in a working plant. In the pre-selection phase, compare the accuracy class and throughput a supplier documents under production conditions, and whether they handle verification and periodic recalibration.

Relevant standards

Non-automatic weighing instruments placed on the EU market fall under Directive 2014/31/EU, and automatic weighing instruments under Directive 2014/32/EU. The corresponding metrological requirements are set out in OIML R 76 for non-automatic instruments, OIML R 51 for automatic catchweighing instruments, and OIML R 61 for automatic gravimetric filling instruments. Suppliers commonly certify quality management to ISO 9001.

Frequently asked questions

Does a checkweigher need legal verification?
It depends on the use. Instruments used to determine quantity for trade or to check prepackage compliance fall under the EU weighing instrument directives; purely internal process checks generally do not. Confirm the intended use before shortlisting.
