Glossary: weighing technology

Analog/digital converters are used to convert analog signals (mostly voltages) into digital signals. The conversion process involves a number of steps, including sampling, quantification and coding.

Combination of different types of scales in classes of equal accuracy. According to the international guidelines of the EC there is the following classification: coarse scale = class (IIII), commercial scale = class (III), precision scale = class (II), fine scale = class (I).

Device for weighing or compensating a tare load without using the weighing range of the scale.

Adjustment is the setting (adjustment) of a measuring chain with the aim of keeping measuring deviations small. An intervention in the measuring chain takes place.

Weight storage for scales requiring W&M approval that evaluate and process the weighing data via a connected EDP system. Electronic archiving by means of a data storage device that conforms to guidelines and cannot be manipulated is required. All data transmitted to the computer (such as date, time, weight) are stored for at least three months.

The alibi printer (log printer) is a printer used to consecutively record weighing transactions for weighing installations with connection to EDP systems.

Animal scales are used in agriculture, in veterinary medicine as well as in zoos. They can be designed as mobile single animal scales, floor scales and group animal scales. Digital weighing indicators display weight values and provide interfaces to other systems (e.g., for data processing and storage). Animal scales are equipped with special filter options and animal weighing programs. These provide stable and accurate measurement results, even when animals move on the scale and generate vibrations. Robust and easy-to-clean materials such as stainless steel are used for the weighing electronics. SysTec weighing terminals have proven themselves in various livestock scales.

 

Type approvals or test reports are issued by a notified body (e.g. PTB in Germany, NMi in the Netherlands). A scale can only be verified if a corresponding valid approval is available.

Abbreviation for ATmosphères EXplosibles. The ATEX directive regulates the use of equipment and components in potentially explosive industrial environments within the EC. Explosion hazards can be caused by flammable substances such as gas, steam, mist or dust.

Scales where the weighing process is carried out without interaction of the operating personnel.

A distinction is made between:

  • Automatic gravimetric filling instruments (AGFI)
  • Automaticdiscontinuoustotalizers (bulk weighers)
  • Automatic continuous totalizing weighing machines (conceyor belt weighers)
  • Automatic checkweighing instruments (checkweighers)
  • Automatic railroad scales

Axle weighers or axle load scales are used to determine the axle load of a vehicle. In order to ensure safe transports, a balanced weight distribution on the individual axles of a vehicle is important. Unacceptable overloading of trucks and other vehicles can be avoided with axle load scales and wheel load scales, so that no fines are incurred. Axle load scales belong to the category of truck scales / vehicle scales.
