PS 750.X7 Precision Balance

PS X7 Precision Balances are distinguished by their simplicity of use, clarity of menu and intuitive layout of information on the display. Much of this is due to the 7-inch touchscreen display, but the latest generation of capacitive display, which provides maximum operating comfort, is not the only advantage of these balances.

Precision and comfort

PS X7 Precision Balances have a readability [d] of 1 to 10 mg, and a maximum capacity [Max] of 200 to 10,100 g; both of these parameters vary depending on the model. An advantage of this series balances is internal (automatic) adjustment, which relieves the user from having to carry out this complicated and precision-demanding procedure himself.

The PS X7 balances are equipped with two infrared sensors, which allow for non-contact operation. Built-in IR sensors allow numerous operations (e.g. tarring, transmitting the result to a printer or selecting successive steps of a particular process, etc.) to be performed handsfree, by simply moving a hand across the sensor. The balances housing is made of plastic, and the pan is made of stainless steel.

New Possibilities

PS X7 Precision Balances enable user to design the layout of the information on the display through a wide selection of widgets. Personalizing the PS X7 balance display gives access to information and operating results directly from the main display panel.

PS X7 Precision Balances are equipped with multiple communication interfaces: 2 x RS232, USB-A, USB-B, Ethernet and Wi-Fi^®. The balances housing is made of plastic, and the pan is made of stainless steel.

Databases

In PS X7 Precision Balances the information system is based on 9 databases which allow several users to work with database storing several products. The registered weighing results can be subject to further analysis.
The data is registered in 9 databases:

Products (5 000 products)
Users (100 users)
Packaging (100 packaging types)
Customers (1 000 customers)
Formulations (100 formulations)
Formulations reports (500 reports)
Ambient Conditions (10 000 records)
Weighings (50 000 records)
ALIBI memory (512 000 records).

Weighing Data Management

USB interface facilitates quick transfer and copying of any results of your work (measurements, reports, databases) to a computer or another balance. Data management on the balance is also possible online, through remote access to the balance and its database.

ALIBI Memory

PS X7 Precision Balances feature ALIBI memory, which guarantees safety as it automatically records measurements, and allows data prereview, copying and archiving.

The ALIBI memory allows to record up to 512 000 weighment records.

Under-pan weighing

Weighing instruments purchased after 15th February 2023 will allow under-pan weighing at any time after the purchase. All you need to do is just to order a dedicated hook.

THBR 2.0 System

Cooperation with THBR 2.0 System for ambient conditions monitoring.

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.

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.

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.

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.
