Balance de précision WLC 120/C2/K

La balance de précision WLC est conçue pour l’indication rapide et précisive de masse dans les conditions laboratoires et industrielles.

l’interface

Elle peut aussi être utilisée aux lieux privés d’accès au réseau secteur (230V) parce qu’elle est équipée d’un accumulateur interne et de l’interface RS 232.

La balance de précision WLC possède le plateau en acier inoxydable et l’afficheur rétroéclairé LCD qui garantit une bonne lisibilité des résultats.

Fonctions

Plus/Minus Control

Control of sample's mass carried out with reference to specified MIN and MAX thresholds. The weight is considered to be correct if it is comprised within threshold values. A graphic visualisation of weighing result is displayed in a form of a bar graph.

Percent Weighing

Percent Weighing function is used for comparision of measured products with mass standard. Mass of a mass standard may be a numeric value taken from a database or it may be determined through a measurement process. Each measured product is compared to mass standard, mass of which is presumed as a model 100% ideal mass. For products weighing less than the mass standard, obtained results are lower than 100%, for products weighing more, the obtained results are greatly exceeded.

Totalizing

Function adding new mass value to already obtained one. This allows to determine mass content of the mixture, being a composition of number of different consistence components. Totalizing is limited by maximum capacity parameter.

Parts counting

Function using mass measurement for determination of measured items quantity. Mass of a single item is required for this process. It may be either estimated through weighment or taken from a database. For items counting the following algorithm is used: all items mass / single item mass = quantity. Function operation is supperted by a mechanism of Automatic Correction of Accuracy. This allows to update single item mass in course of the process. To a certain extend Automatic Correction of Accuracy eliminates error which may be a result of different mass values of seemingly alike single elements. For industry solutions items counting may be simultaneously carried out with checkweighing and dosing thus industry solutions feature audio signalling base informing that specified number of items has been weighed. It is possible to apply weighing systems using few platfroms of different MAX capacities and different accuracies.

Internal battery

Internal and rechargeable battery of SLA 6 V type (sealed lead acid) enables device operation without connecting the device to the mains (9h operation). The weighing instrument controls battery status and displays a respective pictogram on the screen.

Peak hold

Function registering the greatest temporary indication occurring in course of the weighing process. It is most often used in medical scales in order to hold the measurement indication.
