Após mais de meio ano de desenvolvimento técnico e testes funcionais, os analisadores de umidade halógenos das séries VM-S, VM-Q, WKT-E, DHS e VM-TH da VicoMeter obtiveram com sucesso os relatórios de certificação CE-EMC
The IEC (International Electrotechnical Commission) defines electromagnetic compatibility as follows: a system or device can function properly in its electromagnetic environment without causing interference to other systems and devices.
Para padronizar a gestão da compatibilidade eletromagnética de equipamentos elétricos entre os Estados-Membros da UE e harmonizar seus regulamentos de CEM, a Diretiva CEM 89/336/EEC foi emitida em 1º de maio de 1989 e tornou-se obrigatória em 1º de janeiro de 1996; a diretiva atual é a 2004/108/EC. A Diretiva CEM atualizada tem o número 2014/30/EU e entrou em vigor em 18 de abril de 2014. A antiga Diretiva CEM 2004/108/EC foi revogada em 20 de abril de 2016.

The EMC Directive of CE certification requires that the electromagnetic emissions generated by all electrical and electronic products and equipment containing electrical or electronic components must not exceed specified limits, so as not to interfere with the normal operation of other equipment; products must also have a certain level of immunity so that they can operate normally under normal conditions (that is, they can resist electromagnetic interference emitted by other devices that is below the limits allowed by industrial standards).
1. Product manual;
2. Product structure description;
3. Product electrical schematic diagram and printed circuit board diagram;
4. List of key EMC components of the product;
5. Other relevant documents required when necessary;
6. Copies of certification certificates for key safety components of the product;
7. Descrição das diferenças entre modelos de produto dentro da mesma unidade de aplicação.
1. EMC includes EMI (interference) and EMS (susceptibility), that is, electromagnetic interference and electromagnetic susceptibility.
2. EMI, electromagnetic interference, describes the degree of electromagnetic radiation interference a product causes to other products, and whether it will affect the normal operation of the surrounding environment or other electronic or electrical products within the same electrical environment; EMI further includes conducted interference CE (conduction emission), radiated interference RE (radiation emission), and harmonics
harmônica.
3. EMS, suscetibilidade eletromagnética, descreve se um produto eletrônico ou elétrico será afetado por interferência do ambiente ao seu redor ou de outros produtos eletrônicos ou elétricos no mesmo ambiente elétrico, afetando assim seu próprio funcionamento normal.
EMS further includes electrostatic discharge immunity (ESD), radio frequency immunity (EFT), electrical fast transient/burst immunity, surge immunity, voltage dip immunity (Dip), and other related items.
