Title
(EN) LIQUID-LEVEL DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION DE NIVEAU DE LIQUIDE
(JA) 液面検出装置
Abstract
(EN)
This liquid-level detection device (100) for detecting the position of a liquid level is provided with a sensor part (1), a metallic pipe (22), and a body (21). The sensor part is capable of transmitting and receiving ultrasonic waves. The metallic pipe forms a propagation path through which ultrasonic waves transmitted from the sensor part propagate. The body retains the metallic pipe and the sensor part. The metallic pipe is grounded.

L'invention concerne un dispositif de détection de niveau de liquide (100) destiné à détecter la position d'un niveau de liquide, pourvu d'une partie détecteur (1), d'un tuyau métallique (22) et d'un corps (21). La partie détecteur est capable d'émettre et de recevoir des ondes ultrasonores. Le tuyau métallique forme un trajet de propagation à travers lequel se propagent des ondes ultrasonores émises par la partie détecteur. Le corps retient le tuyau métallique et la partie détecteur. Le tuyau métallique est mis à la terre.
