Abstract

"DISPOSITIVO E MéTODO PARA DETECçãO SEM CONTATO DO ESTADO ROTACIONAL DE UM ROTOR". A presente invenção se refere a um dispositivo e método para detecção sem contato do estado rotacional de um rotor (10). O rotor apresenta uma superfície dividida em uma parte eletricamente condutora (1e) e uma parte eletricamente não-condutora (1f) Três bobinas elétricas (2a, 2b, 2c) são individualmente incluídas em um respectivo circuito ressonante paralelo, e são aplicadas próximo ao percurso rotacional e com seus eixos longitudinais orientados na direção do dito percurso rotacional, da parte eletricamente condutora do rotor. As oscilações ressonantes são amortecidas dependendo da posição rotacional do rotor. O estado rotacional é avaliado com um circuito eletrónico. Em um medidor de fluxo de líquido, as bobinas podem ser aplicadas na parte seca do medidor.
