Title
(EN) PILE TESTER

Abstract
(EN)
A self-contained unit has a probe (N) urgeable against a structure to be tested, means (H, I, J, F, M) for applying a shock to the structure through the probe (N), and transducer means (A, B, C) for receiving resulting vibrations from the structure through the probe (N) and providing electrical output data. The unit may also include a memory (b) for storing the data. The unit may have a tubular body (E) in which the transducer means (A, B, C) is receivable. The transducer means (A, B, C) may be linked to a weight (H) and springs (G, I) such that urging the probe (N) against a structure progressively compresses springs (G, I), drives the enclosure (A, B, C) into the body (E) and raises the weight (H) until it is suddenly released and hits the transducer means (C) to supply the shock.
(FR)
L'unité autonome comprend une sonde (N) pouvant être plaquée contre une structure à tester, des organes (H, I, J, F, M) d'application d'un choc contre la structure à travers la sonde (N), ainsi que des transducteurs (A, B, C) recevant les vibrations qui en résultent en provenance de la structure à travers la sonde (N) et fournissant des données de sortie électriques. L'unité peut également comporter une mémoire (b) de stockage des données. L'unité peut être composée d'un corps tubulaire (E) dans lequel peuvent être reçus les transducteurs (A, B, C). Les transducteurs (A, B, C) peuvent être reliés à un poids (H) et à des ressorts (G, I), de sorte que le fait de plaquer la sonde (N) contre une structure comprime progressivement les ressorts (G, I), enfonce l'enceinte (A, B, C) dans le corps (E) et soulève le poids (H), jusqu'à ce qu'il soit soudainement relâché et vienne heurter le transducteur (C), produisant ainsi le choc.
