Balance de précision PS 750.R1

Les balances PS R1 ont été équipées d’interfaces de communication : 2 x RS 232, USB de type A, USB de type B et Wireless Connection optionel.

D’interfaces de communication

La balance peut coopérer avec un ordinateur par l’intermédiaire de l’interface USB, cependant elle a besoin d’équipement supplémentaire (le contrôleur) qui peut être téléchargé de site Internet – la section ‘Logiciel’ ou la section ‘Soutien’.

Le boîtier de la balance est fait en plastique, par contre le plateau de la balance est fait en acier inoxydable. Un opérateur peut peser des charges sous la balance – la charge est suspendue sous la balance.

Les bases individuelles

Dans les nouvelles balances de series R, le système d’information se compose de 5 bases de données, qui permettent le travail de plusieurs opérateurs avec plusieurs articles et en plus de la saisie des pesées.

L'étendue des données qui peuvent être enregistrées dans les bases individuelles:

utilisateurs - 100 différents utilisateurs,
produits - 1000 différents produits,
tares - 100 différentes masses des emballages,
pesages - 5 000 mesures suivantes,
ALIBI - 100 000 mesures suivantes.

USB

L’échange de données dans le système se déroule de façon bi-directionelle à l’aide de l’interface USB. Les nouvelles balances permettent d’importer et d’exporter des bases de données en profitant de clés USB.

L’accès direct aux bases de données se déroule à l’aide de clavier :

Database – l’accès direct aux bases de données
Function – l’accès direct aux fonctions de base
F1 jusqu’à F4 – touches de fonction programmables et touches de navigation du menu.

La mémoire ALIBI

garantit la sécurité de données et permet l’enregistrer jusqu’à 100 000 pesages. Cela assure la sécurité de l’enregistrement des données durant une longue période.

Pesage sous la balance

Le pesage sous la balance ne sera possible que sur une balance équipée de cette fonction dans le processus de production. La nécessité d'une telle fonctionnalité (payante en plus) doit être signalée au stade de la passation de la commande.

Autotest

Diagnostic function aiming at metrological parameters determination (repeatability), the parameters are determined for the actual conditions of use. When speaking of repeatability it may be also used for weighing time optimization. Autotest is operated in an automatic mode thus operator’s time is saved.

Dosing

Weighing process for which reference mass has been determined together with tolerance for its determination. Dosing tolerance is given in [%] and it is calculated in relation to the reference value thus being a permissible deviation of this process. This solution is used for weighing powders, liquids and loose materials. Dosing function performance is often supported with bargraph - load indicator. For industrial scales it is possible to use a control systems of dosing process.

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.

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.

Checkweighing

Checkweighing function is used for checking whether the measured sample mass is within the predefined threshold values, Low [LO] and Hgh [HI]. The thresholds are given in [g] and [kg] units. Current state of a sample being measured is signalled by means of pictorgams located on a display for laboratory balances, for industrial scales Stackligt System is used. This visual +/- inspection is in operation during segregation, control or packing process of products for which mass has bees determined with a specifaied tolerance, eg. 12860 g 961

Animal weighing

Process of mass determination for a product which may unwillingly reposition within the weighing pan. Mass determination in such cases requires much longer period of time when compared to typical weighing process. It is the user who defines period of time needed for control of measured product mass. The user can thus optimize the function depending on the measured product characteristics.

Density determination

Liquid or solid body density function uses the Archimedes principle and it requires a special kit to be applied. The kit when used, replaces a weighing pan. For solids mass of the sample must be determined first in the air, next in the liquid of specified density. For liquids the so called sinker, density of which has been determined, must be measured first in the air, next in the tested liquid. The density determination process is disturbed by air bubbles which may stick either to the measured sample or the sinker. In case of laboratory equipment very light solids may be measured. For industry, solid bodies density may be determined by means of under-pan weighing. Tested load of significant size may be measured this way.
