Acelerómetros Industriais de Alta Temperatura

A IMI Sensors é um fornecedor global de instrumentação de monitorização de condições a altas temperaturas. Frequentemente utilizados em ambientes industriais exigentes, estes sensores de vibração fornecem dados críticos para a deteção precoce de falhas em máquinas.

Os nossos acelerómetros ICP® de alta temperatura com eletrónica interna têm a melhor capacidade de temperatura de qualquer modelo comparável atualmente no mercado, com temperaturas de funcionamento contínuo até 325 °F (162 °C). Para aplicações que excedam estas temperaturas, a IMI Sensors oferece uma variedade de acelerómetros de carga sem amplificadores internos que podem operar até 1200 °F (649 °C).

Mecânica central de um acelerómetro de modo de carga

Alguma vez se perguntou como é que os acelerómetros de carga convertem o movimento físico em sinais eléctricos quantificáveis? Na sua essência, estes dispositivos utilizam cristais sensores dispostos com precisão, firmemente fixados a uma massa sísmica. O conjunto é ainda estabilizado por um anel ou pino de pré-carga que exerce a força suficiente para garantir que toda a estrutura permanece rígida e se comporta linearmente sob várias condições. Quando sujeita a aceleração, a massa sísmica exerce pressão sobre os cristais, gerando uma carga eléctrica proporcional à força aplicada. Esta saída eléctrica é captada por eléctrodos, transmitida através de fios para um conetor elétrico e, por fim, ligada a um cabo de baixo ruído para garantir uma retransmissão de sinal clara e precisa.

Apresentando o elemento UHT-12

O UHT-12™ é um novo cristal concebido para aumentar a precisão e reduzir o ruído durante grandes variações de temperatura. A tecnologia UHT-12™ minimiza eficazmente o impacto das variações de temperatura, abordando a questão comum do fenómeno piroelétrico. Estes fenómenos podem levar a "picos" indesejáveis nos dados, perturbando o desempenho do acelerómetro e distorcendo os resultados dos testes. Os acelerómetros fabricados com a tecnologia UHT-12™ melhoraram a qualidade dos dados e as suas caraterísticas:

  • Embalagem hermética para fiabilidade a longo prazo
  • Sem saída piroeléctrica - apenas medições precisas e de baixa frequência
  • Sensibilidade mais consistente ao longo de uma ampla mudança de temperatura
  • Cristais de modo de cisalhamento para evitar erros de medição transversais e de deformação da base
