The assembly has a sealing unit including a joint (10) placed in a junction plane (P) between a sensor casing (2) and a main casing (8). The sealing unit includes a protection collar (11), which is secured to the main casing. The collar is projected from the main casing by surrounding the junction plane. The collar partly covers the sensor casing by leaving from the sensor casing and leaving a set of assembling clearances (J), where height (H) of the collar is less than six times of value of the clearance. The collar is filled with a sealing material. The sealing material is selected from a group consisting of flexible crosslinkable elastomer resin of type epoxy, polyurethane, acrylate or silicone. The sealing material is rubber or viscous grease. The casings are made of a plastic material and aluminum. |
