Acelerómetros de alta temperatura con modo de carga

Los acelerómetros de salida en modo de carga de PCB® utilizan elementos sensores piezocerámicos que emiten una señal de carga electrostática proporcional a la aceleración aplicada. Estos sensores pueden funcionar a temperaturas extremadamente altas porque no contienen la electrónica de acondicionamiento de señal incorporada que limita el rango de temperatura de los acelerómetros ICP®. Los sensores de modo de carga se utilizan en las pruebas de turbinas de gas y vapor, motores a reacción, motores de alta potencia, sistemas de escape y motores de automóviles, donde las temperaturas pueden oscilar entre 260° C (500° F) y 649° C (1200° F).

Se requiere un acondicionamiento externo de la señal para interconectar las señales de medición del modo de carga con los instrumentos de lectura o registro. Las señales de salida de carga pueden acondicionarse con un amplificador de carga de tipo laboratorio o con un convertidor de carga fijo en línea. Cada uno de estos productos convierte la salida de carga en una señal de tensión de baja impedancia.

Es importante tener en cuenta que la resolución de las mediciones y la respuesta a baja frecuencia de los sistemas de detección en modo de carga dependen de las características del ruido de fondo y de la constante de tiempo de descarga de los dispositivos de acondicionamiento de señal y de lectura utilizados.
