Company information

Elektronikwerk GmbH
Elektronikwerk GmbH
ELEKTRONIKWERK, a young and ambitious company based in Vreden, is a leader in the field of weighing technology and is passionately dedicated to precise weight recording. Our wide range includes everything from parcel scales to state-of-the-art weighing systems for silos or containers as well as special scales for the precise recording of weights for animals and vehicles. We offer scales and weighing systems in the legal-for-trade range, but also in the non-legal-for-trade range, just as required and desired. What particularly characterises us is the versatility and user-friendliness of our systems. In addition to the clear display via large or remote displays, we offer seamless integration of weighing results into software programmes and the option of easy printing via external devices. Our weighing systems are equipped with interfaces for PLCs or other control systems to ensure smooth communication and integration into existing processes. Our top priority is to offer solutions that are as simple as possible and only as complex as the requirements demand. We use display devices that are developed and produced by us in our factory, but also, if necessary, devices that we purchase from our numerous partners. However, the name ELEKTRONIKWERK not only stands for outstanding expertise in weighing technology, but also for the ability to think beyond the boundaries of this specialist field. If you need support in developing and realising your products from the initial idea to series production, we are your reliable partner. Our highly qualified team combines more than a century of experience in the fields of weighing technology and electronics, and we are always ready to utilise our knowledge and innovative strength for your success. We are an authorised repairer for non-automatic weighing instruments of class III up to 70000kg, approved by the NRW Weights and Measures Directorate. For you, this means that we are authorised to destroy the verification marks of the verification office when repairing your still calibrated scales. After successful repair and testing with calibration weights, these are then replaced by repair marks. As a customer, you may then continue weighing directly in legal metrology. We will be happy to take care of subsequent recalibration of the scales.
