Amplificadores de carga de elevado desempenho

Concebidos para utilização com acelerómetros de carga e sensores de pressão

A gama de amplificadores de carga da IMI foi especificamente concebida para melhorar o desempenho de acelerómetros e sensores de pressão em modo de carga. Estes dispositivos convertem as saídas de sinal de alta impedância em saídas de sinal de baixa impedância, assegurando medições claras e precisas mesmo em condições extremas, incluindo temperaturas até +500 °F. Esta capacidade é crítica, pois permite que os amplificadores de carga funcionem eficientemente com sensores de modo de carga de alta temperatura que exibem valores de resistência de isolamento mais baixos.

Amplificadores de carga de terminação simples vs. diferencial

Os amplificadores de carga de terminação única são ideais para configurações que utilizam sensores de terminação única com cabos coaxiais, em que o pino ou condutor do cabo transporta o sinal e o invólucro do conetor ou a blindagem do cabo serve como terra. Isto é particularmente adequado para ambientes onde a simplicidade e a relação custo-eficácia são prioritárias.

Os amplificadoresde carga diferenciais são concebidos para aplicações mais exigentes, em que os amplificadores de carga aceitam sinais positivos e negativos simultâneos. Estes sinais são iguais em amplitude mas opostos em fase, permitindo que o ruído de modo comum afecte ambos os sinais de forma igual, melhorando assim a integridade do sinal mesmo em ambientes ruidosos.
