Abstract
A test apparatus for testing an IR sensor of train undercarriage temperatures is disclosed. The IR sensor may be used to obtain infrared IR emission data by sensing a wheel or a wheel bearing of a rail vehicle. The test apparatus may comprise a heat emitter for supplying IR emissions at a reference temperature to the IR sensor. A support may support the heat emitter at a position spaced from the passage of the rail vehicle and in an orientation for directing the IR emissions at the IR sensor.
Claims15
A test apparatus for an IR sensor of a rail vehicle undercarriage component, the test apparatus comprising:
- a heat emitter for producing IR emissions at a reference temperature;
- and
- a support for supporting the heat emitter at a position spaced from the passage of the rail vehicle and in an orientation for directing the IR emissions at the IR sensor.
A method of testing an IR sensor of a rail vehicle undercarriage component, the method comprising the steps of:
- providing a heat emitter for producing IR emissions at a reference temperature;
- supporting the heat emitter on a support at a position spaced from the passage of the rail vehicle and in an orientation for directing the IR emissions at the IR sensor;
- activating the heat emitter to produce IR emissions at the reference temperature;
- and
- comparing the reference temperature of the IR emissions and the temperature detected by the IR sensor.
