Abstract
An event monitoring sensor apparatus for detecting vibration signals emitted from a machine. In one aspect, the apparatus includes a housing, an inner chamber within the housing, a sensor at a first position of the inner chamber, and an electrical connection that electrically connects to the sensor. The apparatus further includes an attachment mechanism at least partially enclosed within the inner chamber and located at a second position of the inner chamber. In some examples, the attachment mechanism is removably attachable to a machine to seal the inner chamber from external noise.
Claims10
A sensing apparatus for detecting ultrasonic waves from a vibration-generating machine, the sensing apparatus comprising:
- a housing;
- an inner chamber within the housing;
- a sensor at a first position of the inner chamber, wherein the sensor is configured to detect ultrasonic waves and convert the ultrasonic waves to electrical signals;
- an electrical connection that electrically connects to the sensor and is configured to output the electrical signals from the sensor;
- and
- a magnet at least partially enclosed within the inner chamber and located at a second position of the inner chamber opposite the first position, wherein the magnet is configured to removably attach to a machine to acoustically seal the inner chamber from external noise through a direct attachment to a surface of the machine.
A system for machine diagnostics comprising:
- a machine with an engine that is configured to cause the machine to vibrate;
- a sensing apparatus attached to the machine, the sensing apparatus comprising:
- a housing;
- an inner chamber within the housing;
- a sensor at a first position of the inner chamber, wherein the sensor is configured to detect ultrasonic waves and convert the ultrasonic waves to electrical signals;
- an electrical connection that electrically connects to the sensor and is configured to output the electrical signals;
- and
- a magnet at least partially enclosed within the inner chamber and located at a second position of the inner chamber opposite the first position, wherein the magnet is configured to removably attach to a machine to acoustically seal the inner chamber from external noise through a direct attachment to a surface of the machine.
