Terminal de pesage PUE 7.1

Terminal de pesage PUE 7.1 est conçu pour les constructions des balances industrielles tensometriques.

Ergonomie et confort de travail

Le terminal est équipé d’un afficheur TFT 5,7’’ avec le panel tactile, d’un clavier à membrane et de deux senseurs de mouvement desquelles fonctions sont programmées de niveau de menu.

Le terminal peut être connecté à deux plate-formes de balance au maximum. De plus, on peut le connecter aux lecteurs de code-barres, aux imprimantes, aux étiqueteuses, au lecteur RFID et à l’équipement PC (une souris, un clavier, une mémoire flash USB). Le terminal PUE 7.1 en version de standard dessert une plate-forme de balance et possède une interface de communication élargiée. L’interface de communication élargiée contient : 2x USB, 2xRS 232, Ethernet, 4 entrées/4 sorties (digitales), Wi-Fi^®.

Le terminal PUE 7.1 peut être élargié par l’addition d’un module d’une plate-forme supplémentaire DP-6.

Attention : pour la version avec deux plate-formes de balance, le terminal peut être réalisé avec le câble (la réalisation en version /R n’est pas possible).

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.

Labelling

Marking products with the right symbols contributes to quick and reliable identification. The balance/scale usually transfers product mass or product quantity to the label printer. The transferred value is printed with the following information: bar code, pictogram, content, address etc. In laboratory the labelling is performed in a semi-automatic mode, for industry in an automatic one (dynamic scales).

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.

Formulation

Function supporting the mixture making process, wherein the mixture contains various components. Formulation function usually uses the balance/scale database of components. Formulation serves for monitored checkweighing of every single component with a given tolerance. It is enriched with a set of individual settings.

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.

Differential weighing

Differential weighing informs about mass variation a particular sample, wherein the said variation is a result of manufacturing processes.

Differential weighing is often applied in product control process, for which reference product parameters have been specified in order to be used as a source of comparison for the whole series.
Insuchcasestandard deviation is the information which tells about quality and completeness of a final product. For systems based on a feed-back technique such information may be used by control units.

ALIBI Memory

"ALIBI" memory enables saving and storing up to 100000 measurements. Measurements are saved automatically upon each pressing of the key. There is no need for any additional operations or changing settings.
The following data related with the measurements is saved: measurement date; measurement time; result (mass); tare value; operator carrying out the measurement (logged in); product name.
The software saves the measurement in a so called loop, i.e. when the measurement no. 100001 is saved, the measurement 1 gets automatically deleted from the memory.
Measurements saved to balance memory cannot be deleted.
You can preview and print out the data saved to the ALIBI database.
