The invention relates to a piezoelectric crystal with transversal effect which may be fitted into a sensor without centering effort or the use of other means, yet assuring a centered and aligned position. For this the crystal according to the invention has a base with at least individual circular segments, which can be fitted into a drill provided for it in a holding device of the sensor. Moreover the crystal production can be automated for mass production, thereby lowering its costs. |
