Sensor mounting assembly for machine condition monitoring

摘要

A sensor node with a mounting assembly and methods of using the same for affixing a sensor node to a machine to detect, isolate, and diagnose machine faults are discussed. An exemplary mounting assembly includes a base with a substantially centered through hole, and a fixation member operatively to pass through the through hole and engage the base. The sensor node includes a circuit board with circuitry to sense information of machine characteristic. The circuit board defines a guide hole concentrically aligned with the through hole on the base to allow the fixation member to pass through said holes. The base can be fixed directly to the machine by the fixation member, or via a mounting pad. A network of sensor nodes may communicate with a cloud-based computing device that provides a cloud-based service to detect a machine fault or to diagnose a fault type.
