Abstract

Esta solicitud describe un aparato para registrar la operacion de una válvula (10) del tipo que tiene un husillo (18) girable por una llave (20) para efectuar la abertura y cierre de la misma, el aparato que incluye un medio operativo (36) que se porta en el uso en una llave (20), el medio operativo que es operable de manera independiente de cualquier otro aparato o equipo electronico, para detectar el movimiento giratorio de la llave durante la operacion de la válvula. En forma preferente, el medio operativo incluye un medio sensor (40, 42) sensible al campo magnético de la tierra; y es operativo para determinar la rotacion de la llave por el análisis de las señales generadas por el medio sensor. Al detectar la operacion de la válvula con el medio operativo en una llave, se evita el gasto de proporcionar un medio de deteccion para cada válvula (el numero total de llaves que es mucho menor que el numero total de válvulas), como es la necesidad de proporcionar equipo potencialmente delicado en ambientes hostiles de las válvulas.
