Multifunctional Stainless Steel Ramp Scale 300kg d:100 g HX7.4N.300.H4

Overview

The HX7.4N H scale is a device controlled by means of the PUE HX7 indicator, and it has been equipped with a 4-load-cell ramp platform made of stainless steel, AISI 304. This robust design facilitates weighing of heavy loads in humid environment. The ramps enable easy loading and unloading.

Indicator with a colour 7” graphic display and a diode bar graph allow to observe visualisation of a current load mass presented in relation to the scale range or declared minimum and maximum thresholds. This makes the operation significantly easier. At the back of the housing there are hermetic connectors of RS232, RS485, USB and Ethernet communication interfaces, plus digital inputs/outputs and analogue output. This enables cooperation with external devices such as barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control and superior IT systems.

With use of the bracket you can either place the indicator at any flat horizontal surface, or fix it to the wall adjusting the tilt respectively to suit your needs.
The terminal's software allows carrying out processes such as weighing, parts counting, dosing, labelling, formulations and percent weighing. Indicator’s system of information is based on databases (users, products, weighings, packaging, formulations, customers) and ALIBI memory which guarantees stored data safety.

Functions

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.

Replaceable unit

Weight function to change the weight unit.

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.
