There is described a sealing device (20) for sealing packages (2) filled with a pourable product within a packaging machine (1). The sealing device (20) has at least one sonotrode (21) comprising at least a sonotrode head (23) and a vibration control unit (25) connected to the sonotrode head (23) and configured to actuate ultrasonic vibrations of the sonotrode head (23). The vibration control unit (25) comprises one or more piezoelectric transducer devices (35) configured to generate ultrasonic vibrations to be coupled into the sonotrode head (23) and one or more temperature sensors (36) configured to measure the temperature of the one or more piezoelectric transducer devices (35) for determining and/or monitoring respective operating states of the one or more piezoelectric transducer devices (35).
