Vibro-Meter 144-140-000-011 CA140 Vibration Accelerometer Unit

Feature & Principle

It adopts piezoelectric sensing principle, built-in IEPE constant current drive circuit. Mechanical vibration acts on the piezo crystal and converts vibration acceleration into analog charge signal, then outputs standard IEPE signal to VM600 monitoring card. The system calculates vibration velocity/displacement value, realizes bearing vibration trending, alarm and turbine trip interlock protection.
