Abstract:
(EN) A pressure sensor, comprising: a displacement sensor (40), an elbow pipe (30) and a base (32); a first end of the elbow pipe (30) is fixed on the base (32), the displacement sensor (40) comprises a first reflection member (50) and a second reflection member (51), the first reflection member (50) being fixed in the main body of the displacement sensor (40), and the second reflection member (51) being movable relative to the main body of the displacement sensor (40); the main body of the displacement sensor (40) is fixed on the base (32), and the second reflection member (51) is connected to the elbow pipe (30) at a first position of the elbow pipe (30); alternatively, the second reflection member (51) is fixed on the base (32), and the main body of the displacement sensor (40) is connected to the elbow pipe (30) at a first position of the elbow pipe (30); when the pressure in the elbow pipe (30) changes, the elbow pipe (30) deforms, such that the distance between the first reflection member (50) and the second reflection member (51) changes, and the magnitude of the change of pressure is obtained by means of the displacement measured by the displacement sensor (40).
(FR) L'invention concerne un capteur de pression comprenant : un capteur de déplacement (40), un tuyau coudé (30) et une base (32); une première extrémité du tuyau coudé (30) est fixée sur la base (32), le capteur de déplacement (40) comprend un premier élément de réflexion (50) et un second élément de réflexion (51), le premier élément de réflexion (50) étant fixé dans le corps principal du capteur de déplacement (40), et le second élément de réflexion (51) étant mobile par rapport au corps principal du capteur de déplacement (40); le corps principal du capteur de déplacement (40) est fixé sur la base (32) et le second élément de réflexion (51) est relié au tuyau coudé (30) à une première position du tuyau coudé (30); en variante, le second élément de réflexion (51) est fixé sur la base (32) et le corps principal du capteur de déplacement (40) est relié au tuyau coudé (30) à une première position du tuyau coudé (30); lorsque la pression dans le tuyau coudé (30) change, le tuyau coudé (30) se déforme, de telle sorte que la distance entre le premier élément de réflexion (50) et le second élément de réflexion (51) change, et l'amplitude du changement de pression est obtenue au moyen du déplacement mesuré par le capteur de déplacement (40).
(ZH) 一种压强传感器,包括:位移传感器(40)、弯管(30)、底座(32);弯管(30)的第一端固定在底座(32)上,其中,位移传感器(40)包括第一反射部件(50)、第二反射部件(51),第一反射部件(50)固定在位移传感器(40)的主体中,第二反射部件(51)能够相对位移传感器(40)的主体移动;位移传感器(40)的主体固定在底座(32)上,第二反射部件(51)在弯管(30)的第一位置处与弯管(30)连接;或者,第二反射部件(51)固定在底座(32)上,位移传感器(40)的主体在弯管(30)的第一位置处与弯管(30)连接;弯管(30)内的压强发生变化时,弯管(30)发生形变导致第一反射部件(50)和第二反射部件(51)之间的距离发生变化,通过位移传感器(40)测得的位移得到压强变化大小。
