The basis of Wipotec‘s high precision weighing technology is the monoblock, a masterpiece of machining and entirely manufactured in-house. Advanced CNC systems transform a block of raw aluminum into a high precision instrument. The monoblock forms the basis of the weighing process which employs Electro-Magnetic Force Restoration (EMFR) to determine weight values.
Electro-Magnetic Force Restoration - for the highest accuracy
This advanced weighing method uses the same basic principle as the simple beam balance. The aim is to determine the force applied at the end of a lever arm. In this case, the weight forces a coil installed on the other side of the balance out of its magnetic field. An optical positioning system
senses the smallest displacement and reports this to a high precision control system that readjusts the compensation current and restores equilibrium to the balance. This compensation current is
measured through a precision resistor and further processed by a micro-processor system for immediate output as a digital weight value.
The decisive advantage of the EMFR Weigh Cell – in contrast to the strain gauge process – is provided by the very short settling time. EMFR is extremely fast and supplies highly accurate weight values. Furthermore, they provide space and cost savings when integrated in existing systems. The measurement ranges of the Weigh Cells vary from 1 µg to 120 kg depending on the series.
AVC compensates up to 100% of the disturbances
On request, Wipotec Weigh Cells can be fitted with AVC Technology (Active Vibration Compensa-
tion). AVC provides the foundation for accurate and instantaneous weight measurements even at sites that are subject to external disturbance sources (vibrations from machinery or local conditions). And, it does this without any loss in quality in terms of accuracy and throughput.
Wipotec is highly regarded worldwide for precision work “Made in Germany.“ This quality label is both an incentive and the source of our commitment and simultaneously, the best foundation on which to continue writing the success story, using the same ink in the interest of our customers, that
began with ambition and spirit more than a quarter of a century ago.
