ABSTRACT:
A device for encapsulating a monitoring device for a pneumatic tire with an encapsulation material includes an encapsulation body having an encapsulation chamber. The monitoring device has at least a pressure sensor and an antenna. A damming element is carried by the encapsulation body in an adjustable manner such that the damming element contacts the pressure sensor of the monitoring device when the monitoring device is disposed within the encapsulation chamber. The damming element prevents the pressure sensor from being clogged with the encapsulating material when the monitoring device is encapsulated. The antenna of the monitoring device is held in a channel formed in the body when the monitoring device is disposed within the encapsulation chamber. The connection between the antenna and the body holds the monitoring device in a floating disposition in the encapsulation chamber. The damming element is in the form of a tube that also helps carry the monitoring device in the floating disposition. A breathing tube abuts the pressure sensor and extends through at least a portion of the damming element to further prevent the encapsulation material from clogging the pressure sensor. A top plate of the body extends over the encapsulation chamber to form a lip that serves to indicate when the encapsulation chamber has been filled with the encapsulation material.
