a wear part including a cavity that receives the nose of the base;
a lock for securing the wear part to the base;
a hole in the nose that opens at the exterior surface to face the wear part or the lock when the base, wear part, and lock are assembled together;
a monitoring device within the bore and facing outwardly from the outer surface proximate to the wear part or the lock, the monitoring device detecting the presence and/or absence of the wear part or the lock; a monitoring device that transmits a wireless signal when the wear part or the lock is detected absent.

2. The claim 1, wherein the wear part or the lock comprises a proximity device detected by the monitoring device to determine the presence and/or absence of the wear part and/or the lock. wear assembly.

The wear part includes a lock opening, the lock is received within the lock opening and a hole in the nose to secure the wear part to the base, and the monitoring device indicates whether the wear part has been separated from the base. 2. The wear assembly of claim 1, detecting the presence and/or absence of said lock to identify whether.

The lock includes a tip movable to be received in and out of a hole in the nose, and the monitoring device is positioned within the hole adjacent the tip of the lock when the tip is received in the hole. 4. The wear assembly of claim 3, wherein:

2. The wear assembly of claim 1, wherein the monitoring device is proximate the wear part and detects the presence and/or absence of the wear part.

3. wherein said nose includes a second hole separate from said hole for receiving said lock when said wear part, base and lock are assembled together, said monitoring device being within said second hole. 6. The wear assembly according to 5.

7. The nose includes a front surface, a top surface, a bottom surface and opposed side surfaces, the surveillance device receiving aperture opening into one of the side surfaces and the lock receiving aperture opening into one of the side surfaces. Wear assembly as described in .

A wear assembly for earth work equipment comprising:
a base securable to the digging edge of the earth work machine and including a nose having an outer surface, a first hole and a second hole, wherein each of the first hole and the second hole are in the nose; a base opening into the outer surface of the
said wear member including a cavity for receiving said nose of said base and an aperture extending through said wear member and communicating with said cavity;
a lock received within said opening in said wear member and within a first hole in said nose for securing said wear member to said base;
a monitoring device in the second hole proximate to the wear part for detecting the presence and/or absence of the wear part and transmitting a wireless signal when the wear part is detected absent;
a wear assembly.

The nose includes a front surface and opposite side surfaces, the first hole opening into one of the side surfaces and the second hole opening into one of the side surfaces remote from the first hole. 9. The wear assembly of claim 8, wherein:
