The 960-TX from Columbia has been particularly developed to track vibration produced by commercial and military helicopter engines, transmissions and airfames. The 960-TX consists of three miniature vibration sensors that are mutually perpendicular and embedded into a tough machined housing integrating a single central mounting screw
The 960-TX features combined thick film electronic signal conditioning circuitry which offers temperature compensation, low impedance output drive capability and high sensitivity.
The sensor configuration is suited perfectly to other vibration monitoring applications like structural analysis and aircraft modal, commercial machinery vibration monitoring, and as the key vibration sensor for all prognostic maintenance vibration diagnostic systems.
