The present invention relates to a device for mounting a sensor to a curved component surface. The mounting device (170) has a first side at which the sensor (180) is attached and a second side which has a radius of curvature. Further, the mounting device has an aperture that is shaped to receive an insert part (185) of the sensor, and a first sealing element (191) is provided around the aperture, at the first side of the device. According to the invention, the first sealing element is provided on a first recessed surface of the mounting device, which is defined between a first upstanding rim and a second upstanding rim. The first and second rims extend in a circumferential direction of the device and provide a contact surface for an attachment part (183) of the sensor. In addition, the first and second rims retain the first sealing element in both axial directions.
