Microprocessor-Based Vibration Amplifier

Sensing and monitoring systems supplier Meggitt PLC launched the Endevco model 6634C, a microprocessor-based vibration amplifier that has been designed to condition and display rotating machinery data in simultaneous outputs, such as broadband, acceleration, velocity, and displacement.

Model 6634C is designed to accept inputs from a single-ended, differential piezoelectric or ISOTRON (IEPE-type) 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, 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 10 unique setups can be stored and recalled from the nonvolatile memory, while two TTL-compatible latched alarm outputs provide both warning and alert functions. An optional 19-inch mounting rack from Meggitt Sensing Systems can accommodate up to six units. (
