DEVICE FOR DETERMINING AND/OR MONITORING A PREDETERMINED LEVEL IN A CONTAINER |
摘要 |
A housing (1) has at one end arms (5) projecting to the level monitored and in contact with a stack (13) of piezo electric elements held between two very hard metal plugs (19,21). One plug contacts a circular membrane (3) attached to the arms. A threaded clamping stud (24) adjusts the pressure which the bottom plug exerts on the membrane. The piezo elements act to excite the arms to oscillate and provide signals to the measurement unit - |
