Title
(EN) DETECTOR AND METHODS OF DETECTING
(FR) DÉTECTEUR ET PROCÉDÉS DE DÉTECTION
Abstract
(EN)
An ultrasonic detector (10) suitable for mounting in a position for surveying an area for a source of airborne ultrasound, which detector comprises a sensor (20) for detecting an ultrasonic sound signal, characterised by a transducer (64) configured to produce a broadband ultrasonic sound signal for reception by said sensor (20) enabling said ultrasonic detector to perform a self-test.
(FR)
L’invention concerne un détecteur ultrasonique (10) qui peut être monté en position afin de surveiller une zone et détecter une source d’ultrasons portés par l’air, lequel détecteur comprend un capteur (20) pour détecter un signal de son ultrasonique, caractérisé par un transducteur (64) conçu pour générer un signal de son ultrasonique en bande large qui sera reçu par ledit capteur (20), ce qui permet audit détecteur ultrasonique d’effectuer un autotest.
