Weighing Technology

OPC 40200 Weighing Technology

Description

An OPC UA Companion Specification for Weighing Technology which covers different scale systems.

Scale systems are defined as devices within a value chain that measure the weight or mass flow of a product or Object containing several additional parameters (e.g. price, tare of packaging, etc.). Scale systems stand for a complete weight measuring device that includes one or multiple scales. The scales may fulfil different use cases within one scale system (e.g. filling and price labelling). Each scale consists of one or multiple load cells which capture the weight. It is the smallest unit regarding the components of a scale system within this Companion Specification.
The Companion Specification covers the following scale system types directly: Automatic Filling Scales, Catchweigher (Automatic Price Labelling Scales, Automatic Weight Labelling Scales, Checkweigher), Continuously Scales, Hopper Scales, Laboratory Scales, Piece Counting Scales, Simple Scales, Totalizing Scales and Vehicle Scales.

Other scale systems including weighing bridges may be modelled based on this Companion Specification, but probably need to be extended by certain parameters.
