Método para ajustar la frecuencia de resonancia (fR) de una sección oscilante (3) de una carcasa (2) de un sensor (1), en particular de un sensor ultrasónico, con lo cual, el método presenta las siguientes etapas: (VS1) medición de la frecuencia de resonancia (fRI) de la sección oscilante (3) mediante un dispositivo de medición (15); (VS2) comparación de la frecuencia de resonancia medida (fRI) con un valor umbral anteriormente determinado de una frecuencia de resonancia deseada (fRS); y (VS3) eliminación de material o aplicación de material adicional en la sección oscilante (3) en base a la comparación para ajustar la frecuencia de resonancia (fR) de la sección oscilante (3). The method involves measuring resonance frequency of an oscillating section (3) with a measuring device (15), and comparing the measured resonance frequency with a previously determined threshold value of an actual resonance frequency. A material removal or coating at the oscillating section is established based on the comparison for adjusting the resonance frequency of the oscillating section, where the oscillating section has a covering at an outer side of a housing (2). Independent claims are also included for the following: (1) a housing for an ultrasonic sensor (2) a device for adjusting of resonance frequency of an oscillating section of the housing of the sensor.
