Na \u00c1lava Ingenieros, representamos a LNS Dynamics e a ASC-Sensors, l\u00edderes em aceler\u00f3metros IEPE. Estes sensores incorporam um pr\u00e9-amplificador que converte o sinal para baixa imped\u00e2ncia, permitindo a utiliza\u00e7\u00e3o de cabos longos sem perda de qualidade e minimizando a interfer\u00eancia de ru\u00eddo. S\u00e3o a escolha perfeita para testes modais, monitoriza\u00e7\u00e3o industrial e laborat\u00f3rios. <\/p>\n

Aceler\u00f3metros IEPE da LNS Dynamics e ASC: Precis\u00e3o e fiabilidade para a medi\u00e7\u00e3o de vibra\u00e7\u00f5es<\/b><\/p>\n

No centro de qualquer sistema de monitoriza\u00e7\u00e3o ou teste de vibra\u00e7\u00f5es est\u00e1 o sensor, e a escolha certa \u00e9 essencial para obter dados fi\u00e1veis. Na \u00c1lava Ingenieros, trabalhamos com a LNS Dynamics e a ASC-Sensors, dois dos fabricantes mais conceituados do mundo no campo da tecnologia de sensores. A sua gama de aceler\u00f3metros IEPE (Integrated Electronics Piezo-Electric) representa a solu\u00e7\u00e3o padr\u00e3o da ind\u00fastria para a medi\u00e7\u00e3o precisa de fen\u00f3menos de vibra\u00e7\u00e3o, choque e acelera\u00e7\u00e3o. <\/p>\n

O que \u00e9 a tecnologia IEPE e porque \u00e9 que \u00e9 a mais utilizada?<\/b><\/p>\n

A norma IEPE define um tipo de aceler\u00f3metro piezoel\u00e9trico que incorpora no seu interior a eletr\u00f3nica de condicionamento do sinal (um amplificador ou conversor de imped\u00e2ncia). Quando o cristal do sensor piezoel\u00e9trico \u00e9 sujeito a acelera\u00e7\u00e3o, gera um sinal de carga de alta imped\u00e2ncia, que \u00e9 altamente suscet\u00edvel ao ru\u00eddo eletromagn\u00e9tico e \u00e0 interfer\u00eancia do movimento do cabo. <\/p>\n

A eletr\u00f3nica incorporada num sensor IEPE converte imediatamente esta carga num sinal de tens\u00e3o de baixa imped\u00e2ncia muito mais robusto e est\u00e1vel. Este sinal \u00e9 transmitido atrav\u00e9s de um cabo coaxial padr\u00e3o de dois fios, que simultaneamente alimenta o sensor com uma corrente de excita\u00e7\u00e3o constante do sistema de aquisi\u00e7\u00e3o de dados. <\/p>\n

Principais vantagens dos aceler\u00f3metros IEPE<\/b><\/p>\n

Esta configura\u00e7\u00e3o engenhosa oferece vantagens cruciais:<\/p>\n

    \n
  • Imunidade ao ru\u00eddo:<\/b> O sinal de baixa imped\u00e2ncia \u00e9 inerentemente resistente \u00e0 interfer\u00eancia electromagn\u00e9tica e ao ru\u00eddo triboel\u00e9trico gerado pelo cabo.<\/li>\n
  • Utiliza\u00e7\u00e3o de cabos longos:<\/b> Permite a passagem de cabos at\u00e9 centenas de metros sem degrada\u00e7\u00e3o do sinal, ideal para grandes estruturas ou m\u00e1quinas.<\/li>\n
  • Custo e complexidade reduzidos:<\/b> Utiliza cabos coaxiais de baixo custo e conectores padr\u00e3o (como BNC ou microdot), simplificando a instala\u00e7\u00e3o e a manuten\u00e7\u00e3o.<\/li>\n
  • Intercambialidade:<\/b> Como padr\u00e3o da ind\u00fastria, os aceler\u00f3metros IEPE e ASC da LNS Dynamics s\u00e3o compat\u00edveis com a grande maioria dos sistemas de aquisi\u00e7\u00e3o de dados existentes no mercado.<\/li>\n<\/ul>\n
    Aplica\u00e7\u00f5es ilimitadas<\/b><\/h5>\n

    Desde a monitoriza\u00e7\u00e3o do estado estrutural de uma ponte at\u00e9 \u00e0 an\u00e1lise de vibra\u00e7\u00f5es de alta frequ\u00eancia num motor de combust\u00e3o, os aceler\u00f3metros IEPE s\u00e3o a ferramenta essencial. As aplica\u00e7\u00f5es incluem manuten\u00e7\u00e3o preditiva na ind\u00fastria, testes de ru\u00eddo e vibra\u00e7\u00e3o (NVH) em autom\u00f3veis, testes de vibra\u00e7\u00e3o no solo (GVT) na ind\u00fastria aeroespacial, an\u00e1lise modal, monitoriza\u00e7\u00e3o s\u00edsmica e investiga\u00e7\u00e3o e desenvolvimento laboratorial. <\/p>\n

    A equipa de especialistas da \u00c1lava Ingenieros pode aconselh\u00e1-lo na sele\u00e7\u00e3o do aceler\u00f3metro monoaxial ou triaxial LNS Dynamics ou ASC IEPE que melhor se adapta \u00e0 sua aplica\u00e7\u00e3o.<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
