The invention relates to a device for the ultrasonic processing of materials (20), comprising: an ultrasonic processing system, which consists of an ultrasound generator, a converter (12), a sonotrode (16), and a counter tool (18); and an advancing unit, by means of which the sonotrode (16) and the counter tool (18) can be moved toward each other or away from each other; wherein a force sensor (32) is provided, by means of which the force that the ultrasonic processing system applies to the materials (20) to be processed can be measured. According to the invention, in order to provide a corresponding ultrasonic processing device that enables a higher processing speed, the force sensor (32) is a piezoelectric sensor, the output of which is converted into a voltage by means of a charge amplifier, and a control device is provided, which either short-circuits the piezoelectric sensor if the ultrasonic processing system is not performing material processing or adds a time-varying force compensation value to the value measured by the piezoelectric sensor.
