Scope
Content
This SAE Aerospace Standard (AS) specifies requirements for the interface between a rotational system indexing sensor and its interface electronics. These sensors generate one or more electrical pulses for each revolution of the shaft being monitored. These pulses can be used to determine the actual shaft rotational speed and/or position for use in a Health and Usage Monitoring System (HUMS). Indexing sensors are used in the following HUMS areas on the aircraft: (a) rotor track and balance, (b) engine vibration monitoring and diagnostics, (c) drive train vibration monitoring and diagnostics. The goal of this standardization effort is to be able to take any compliant indexing sensor and connect it to any compliant interface electronics.
These SAE HUMS Interface Specifications include the minimal interface and performance requirements for interoperability with the Rotorcraft Industry Technology Association (RITA) compliant HUMS. Compliance with these Interface Specifications can be referenced in more comprehensive procurement and device specifications.
Rationale
Content
HM-1 Committee reached consensus to stabilize AS5392 document at a previous meeting. Justification is that the documented standard does not reflect approach taken by HUMS suppliers. However, there is useful system functionality data which should not be lost via document cancellation.
