## Abstract

A monitoring system includes a fastener. A sensor is coupled to the fastener. A circuit board is electrically coupled to the sensor. An antenna electrically coupled to the circuit board.

## Claims

### Claim 1

A roller condition monitor, comprising:
a frame coupled to an inside of a roller, where the roller comprising an idler roller;
a circuit board assembly disposed in the frame;
a sensor coupled to the circuit board assembly, the sensor adapted to monitor parameters associated with wear of the roller;
a recessed antenna electrically coupled to the circuit board assembly and extending rearwardly from the frame, the recessed antenna being received into a slot formed in an inner surface of the roller; and
a power source electrically coupled to the recessed antenna.

### Claim 2 (depends on 1)

The roller condition monitor of claim 1, wherein the sensor is at least one of a vibration sensor, a temperature sensor, an accelerometer, or a strain gauge.

### Claim 3 (depends on 1)

The roller condition monitor of claim 1, comprising at least two recessed antennas.

### Claim 4 (depends on 1)

The roller condition monitor of claim 1, wherein the power source is a battery.

### Claim 5 (depends on 1)

The roller condition monitor of claim 1, wherein temperature is monitored in an effort to diagnose failing components.

### Claim 6 (depends on 1)

The roller condition monitor of claim 1, wherein vibration is monitored in an effort to diagnose failing components.

### Claim 7 (depends on 1)

The roller condition monitor of claim 1, wherein gyration rates are monitored in an effort to diagnose failing components.

### Claim 8 (depends on 1)

The roller condition monitor of claim 1, wherein the roller condition monitor is modular.

### Claim 9 (depends on 8)

The roller condition monitor of claim 8, wherein the roller condition monitor may be inserted or removed from the roller.
