assess_vibration_severity
Evaluate vibration severity against ISO 10816/20816 standards for stored signals. Classify machinery condition using signal ID, machine class, and axis parameters.
Instructions
Assess vibration severity per ISO 10816/20816 for a stored signal.
Uses the signal_id pattern (load once, reference by ID).
Signal unit is read from metadata; defaults to 'g' if unknown.
Args:
signal_id: ID of the stored signal.
machine_class: 'I' (small <15kW), 'II' (medium 15-300kW),
'III' (large rigid >300kW), 'IV' (large flexible).
axis: Measurement axis (informational).
