San Juan Capistrano, California, USA – Meggitt Sensing Systems, a Meggitt group division, has announced the successful application of the Endevco® 6634C vibration amplifier in meeting the rigorous demands of jet engine testing and aircraft auxiliary power unit vibration measurements.

The Endevco® 6634C is a microprocessor-based vibration amplifier, designed to condition and display rotating machinery data while offering simultaneous outputs as broadband, acceleration, velocity and displacement. The Endevco® 6634C is designed to accept inputs from a single-ended, differential piezoelectric or ISOTRON® (IEPE) accelerometer, velocity coil or remote charge converter. Full-scale AC and DC output ranges, as well as sensitivity, are user programmable in selectable engineering units and are representative of acceleration, velocity or displacement. Programming is accomplished from the front panel keyboard or optional RS-232 computer interface. Units also have an optional six-pole filter, which may be programmed from the front panel. Up to ten unique setups can be stored and recalled from the non-volatile memory, while two TTL- compatible latched alarm outputs provide both warning and alert functions. An optional 19-inch mounting rack, also available from Meggitt Sensing Systems, can accommodate up to six units.



With its unique versatility to accept and condition multiple transducer output types, the Endevco® 6634C vibration amplifier is ideal for the turbine and generator health monitoring of jet engines, generators, turbines and pumps. They are also well-suited for aerospace engine test cell applications which further incorporate the use of high-temperature accelerometers, or where vibration data is required to be expressed in terms of velocity. These rugged units may also be used with other balanced differential output devices. Additional applications include fixed and mobile test cells for small turbofans, air cyclers, as well as in-laboratory test rigs.

The Endevco® 6634C vibration amplifier is also backed by a five-year comprehensive product warranty, with quantities available for immediate customer shipment.
