Ultrasonic transmitting and receiving device for ultrasonic liquid level sensor, has electrode and contact section connected with respective contact zones of conductor paths in electrically conducting manner by using conductive adhesives

摘要

The device has a piezoelectric unit (24) attached on a carrier plate (11) and including electrodes (25, 26). The electrode (25) faces the plate and arranged at a distance from an edge of a broadside of the piezoelectric unit. The electrode (25) and a contact section are connected with respective contact zones (15, 20) of conductor paths in an electrically conducting manner by using conductive adhesives, which lie on the electrode (25).
