## Abstract

A wheel sensor which is primarily located outside of a pneumatic tire includes a sensor for sensing one or more conditions within the pneumatic tire of a wheel and a connector configured to secure the sensor to the wheel rim; wherein the connector establishes a link between the medium inside the tire and the sensor; and includes a valve which seals when the sensor is removed from the rim and opens when the sensor is attached to the rim.

## Claims

### Claim 1

A wheel sensor which is primarily located outside of a pneumatic tire comprising sensing means for sensing at least one condition within the pneumatic tire of a wheel and an attachment means for securing said sensing means to the wheel rim;
wherein said attachment means establishes a link between the medium inside the tire and said sensing means; and
comprises a valve which seals when the sensing means is removed and opens when the sensing means is attached to the rim.

### Claim 2 (depends on 1)

A wheel sensor according to claim 1, wherein said attachment means attaches to the rim substantially without any part projecting into the inside of the tire beyond said rim.

### Claim 3 (depends on 1)

A wheel sensor according to claim 1, wherein said attachment means is a screw for traversing an aperture in a rim and for attaching to a corresponding recess in a sensor's housing; the screw head being shaped and configured to be retained by said rim within said aperture.

### Claim 4 (depends on 3)

A wheel sensor according to claim 3, wherein said screw incorporates a channel through the screw which forms a conduit for linking the medium inside the tire to sensing means located in said housing.

### Claim 5 (depends on 1)

A wheel sensor according to claim 1, wherein the wheel sensor housing is cylindrical with an end face for engaging the wheel rim; and incorporates a truncated edge portion; whereby when the housing is attached to the rim in close proximity to a bend in the rim profile, the housing is prevented from rotating in use as said edge portion abuts against the rim.

### Claim 6 (depends on 1)

An outer and inner tire combined wheel, comprising a wheel sensor according to claim 1 located within the rim for establishing a link between the medium inside the outer tire and sensing means.

### Claim 7 (depends on 6)

An outer and inner tire combined wheel according to claim 6, comprising a second wheel sensor configured to assess the medium of said inner tire.
