Abstract

Un detonador que incluye un fusible, una unidad de control, un generador de corriente que, en respuesta a una senal proveniente de la unida de control, hace pasar una corriente de prueba cuya magnitud es menor que la magnitud de una corriente actuante a través del fusible y, un dispositivo de memoria en el cual se almacena la senal de estado que depende de la magnitud del voltaje producido por el paso de la corriente de prueba.A detonator that includes a fuse, a control unit, a current generator that, in response to a signal coming from the control unit, passes a test current whose magnitude is less than the magnitude of a current acting through the fuse and, a memory device in which the status signal is stored that depends on the magnitude of the voltage produced by the passage of the test current.
