Why CVM™?
LESS DOWNTIME MEANS MORE FLIGHT revenue
Comparative Vacuum Monitoring (CVM™) smart sensors significantly reduce the time and labor maintenance crews spend monitoring and inspecting airframes for cracks. In what used to take days in the hangar now takes minutes at the gate.
Revolutionize your maintenance program and replace costly inspections at heavy and out-of-sequence checks, and restore thousands of flight hours back to the network across your entire commercial fleet each year.
CVM™ is the first FAA certified, non-destructive, failsafe at-the-gate structural monitoring solution for achieving condition-based maintenance.

HOW DOES IT WORK?
CVM™ technology involves installing smart sensors to vulnerable airframe structure where damage is anticipated to occur. Using a PM200 hand-held diagnostics device, maintenance staff simply connect to the aircraft’s CVM™ sensor arrays to monitor and detect if surface imperfections exist or if there’s a loss in structural integrity.
Confirming airworthiness has never been easier
Once CVM™ smart sensor kits are placed on the high-stress components of an airframe structure, vacuum is applied to the sensor using the PM200. If vacuum pressure is maintained, then no structural crack exists; however, if there is a loss of vacuum pressure then structural health could be compromised, and a crack may exist.
When a crack develops, it forms a leakage path between a sensor’s atmospheric and vacuum galleries, the flaw results in a vacuum level that cannot be maintained. If no flaw is present, the vacuum will remain at a stable level.
