Abstract

An RFID tag reading system affixed to a machine bearing housing is provided. The reading system includes a mobile data collector having an RFID reader for reading a unique identity of the RFID tag, an magnet electro-mechanically connected to the mobile data collector and a magnet mounting pad fixed to the machine housing. The magnet mounting pad having a ferromagnetic contact body for housing the magnet mounting pad and an RFID antenna disposed within the RFID tag for transmitting a unique identity of the RFID tag. The RFID tag is disposed within the ferromagnetic contact body. The magnet is magnetically connected to the magnet mounting pad. The mobile data collector automatically reads the unique RFID tag identity transmitted from the antenna of the RFID tag when the combination mobile data collector and magnet are placed onto the RFID mounting pad.

Claims

1. A magnet mounting pad affixed to a machine housing, the magnet mounting pad comprising;

a ferromagnetic contact body for housing the magnet mounting pad;

an RFID tag having a unique identity and disposed within an unexposed portion of the contact body; and

an RFID antenna integral to the RFID tag, the antenna for transmitting the unique identity of the RFID tag.

2. The magnet mounting pad according to claim 1, wherein the contact body further provides a disk shaped contact body having a bottom portion, a side portion and a top portion.

3. The magnet mounting pad according to claim 2, wherein the unexposed portion provides a well for mounting the RFID tag in the top portion.

4. The magnet mounting pad according to claim 3, wherein the RFID tag is one of sealed within the well and epoxied in place.

5. The magnet mounting pad according to claim 1, wherein the RFID tag is sealed within the well with a potting material

6. The magnet mounting pad according to claim 1, wherein the RFID tag is of a metal mount type.

7. The magnet mounting pad according to claim 1, wherein the unique identity can be one of etched into the body and printed on a label and fixed to the body.

8. The magnet mounting pad according to claim 1, wherein the mounting pad is affixed to the machine bearing housing by being one of epoxied and studded together.

9. The magnet mounting pad according to claim 1, wherein the machine housing further comprises a machine bearing housing.

10. The magnet mounting pad according to claim 1, wherein the RFID tag is associated with a Point ID.

11. The magnet mounting pad according to claim 10, wherein the Point ID may be preloaded into the RFID tag prior to shipment.

12. The magnet mounting pad according to claim 6, wherein the metal type RFID antenna further comprises one of an RFID spiral antenna and a RFID wound inductor antenna.

13. An RFID tag reading system in conjunction with a piece of rotating equipment, the reading system comprising:

a mobile data collector having an RFID reader for reading a unique identity of the RFID tag;

an magnet electro-mechanically connected to the mobile data collector; and

a magnet mounting pad fixed to the machine bearing housing having;

a ferromagnetic contact body for housing the magnet mounting pad;

an RFID antenna disposed within the RFID tag for transmitting a unique identity of the RFID tag;

wherein

the RFID tag is disposed within the ferromagnetic contact body;

wherein

the magnet is magnetically connected to the magnet mounting pad;

wherein the mobile data collector automatically reads the unique RFID tag identity transmitted from the antenna of the RFID tag when the combination mobile data collector and magnet with its mounting magnet are placed onto the RFID mounting pad to form a single system; and

wherein

the RFID tag ID is used by the data collection device to retrieve POINT ID and POINT setting information and automatically initiate measurements that may include vibration and temperature measurements.
