UYA 2.4Y Ultra-Microbalance

The new generation of ultra-microbalances UYA 4Y is designed to meet the highest requirements for determination of mass. Its built-in system of automatic internal adjustment/calibration maintains excellent measurement reliability and accuracy. The device comprises two major components (an indicator and a precise mechanical measuring system which are enclosed separately). Such design eliminates an influence of heat sourcing from instrument’s electronics on its mechanical components and additionally protects it from shocks and vibrations caused by users operating the instrument. All the elements of a microbalance are made of glass and steel which eliminates the impact of electrostatics on the weighing process.

Filterweighing option

This innovative solution enables the user to easily swap the weighing chamber with the chamber for filter weighing, which considerably expands the UYA 4Y ultra-microbalance functionality. The filter weighing chamber is characterized by high ingress protection. Large open-work weighing pan allows precise weighing of filters of various dimensions (max ø100). It is made of stainless steel which makes the chamber resistant to chemicals, colour change, and scratches. The additional chamber does not come standard with the UYA 4Y ultra-microbalance.

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.

STATISTICS

Statistiscs function registers and analyses performed measurements. This supplies the user withthe following information: Max and Min standard deviation, average value, variance, range et.

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

IR SENSORS

Programmable function supporting the weighing process through control of the following options: sliding weighing chamber doors, printout, zeroing, tarring etc. Especially appreciated wherever preventing the balance from soiling is important.

GLP PROCEDURES

Diagnostic function allowing to objectively document performed measurements. GLP procedures may be either presented in a short report form or extended one.

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

AIR DENSITY CORRECTION

Function performing correction of mass measurement indication, wherein the air density is taken into account. It is used in balances with reading unit < 0,01 mg.

AUTOMATIC SLIDING DOOR

Automatic side panes opened via touch-free IR sensors.

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.
