Ultrasonic transducer with a piezoceramic and method for producing an ultrasonic transducer of this kind

A method for producing an ultrasonic transducer for the measurement of fluid volumes, the ultrasonic transducer including:

• a housing in which a contact element and a piezoceramic are arranged, where said piezoceramic includes two electrodes of different polarity which are applied onto different sides of the piezoceramic, where contact surfaces for electrical contact of the two electrodes are arranged on the same side of the piezoceramic;
• and
• the contact element includes at least two contact sections of different polarity, where the contact element forms a part of the housing, wherein
• the contact element is pot-shaped, where the contact sections are arranged at a base of the contact element and are electrically contactable by way of edge sections of the contact element protruding from the base, the method comprising:
• a. arranging said piezoceramic in said housing so that said contact surfaces of said piezoceramic are in electrically conductive contact with said contact sections of said contact element which are of corresponding polarity;
• and
• b. closing said housing with a lid.
