Crystal element for piezoelectric sensors

摘要

A piezoelectric crystal has a transverse effect and the crystal is designed as one flat plate (22) and at least one base (21) normal to this plate. The base on at least one side (21) juts out over the thickness of the plate. At least two surfaces of the plate (15,16) have an electrically-conducting layer (17,18). Independent claims are included for the following: (1) An arrangement of two identical crystals, (2) A piezoelectric sensor for receiving signal reception, (3) A method for manufacturing a piezoelectric crystal with transverse effect.
