Cantar cu certificare EX WPT 3/H1/K/EX Cantar cu certificare EX WPT 3/H1/K/EX

Cantar cu certificare EX WPT 3/H1/K/EX

Cântarele rezistente la apa ,  din familia WPT/H EX ,  sunt construite pentru a funcționa atat în zone cu risc de explozie cat si in zone cu umiditate ridicata.

Atat indicatorul electronic cat și platforma de cântărire respecta normele in materie de risc de explozie (anti EX). Alimentarea cantarelor se face printr-o sursa externa , model  ZRi02.

 Alimentatorul trebuie localizat  în afara zonei EX.

Pentru protectie , alimentatorul este echipat cu o barieră realizata cu diode. Lungimea cablului de alimentare a indicatorului poate fi de maxim 20 de metri.
Seria WPT/H EX este proiectata să funcționeze în zone EX de tip  1 și 2 unde exista probabilitatea de a fi prezente amestecuri de vapori explozivi si/sau gaze care pot fi  incluse in clasa de explozivi IIB și clase de temperatură T1, T2, T3 și T4.
 Deasemenea cântarele din seria WPT/H EX sunt destinate să funcționeze  în zone cu umiditate ridicată sau in contact direct cu apa. Cantarele sunt echipate cu un indicator realizat din oțel inoxidabil, model PUE C31/H . Indicatorul este conectat la platforma de cântărire printr-un cablu lung de 3 m și este echipat cu un suport ce faciliteaza plasarea pe o masă de cântărire sau pentru montarea pe perete.
 Componentele platformei de cantarire  sunt realizate integral din oțel inoxidabil OH18N9.

Function adding new mass value to already obtained one. This allows to determine mass content of the mixture, being a composition of number of different consistence components. Totalizing is limited by maximum capacity parameter.

Plus/Minus Control

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

Function registering the greatest temporary indication occurring in course of the weighing process. It is most often used in medical scales in order to hold the measurement indication.

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.

Function allowing to perform the measurement in Newton unit, it may be used for processes aiming to determine force resulting in the sample damage.

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 optimaze the function depending on the measured product characteristics.
