Products Description
The Bently Nevada 990 Vibration Transmitter is specifically designed for OEMs integrating small compressors, pumps, motors, or fans, providing a single 4-20 mA vibration signal directly into their control system. This compact, loop-powered device works seamlessly with a 3300 NSv probe and the matching 5 m or 7 m extension cable, converting probe signals into peak-to-peak vibration measurements in engineering units while delivering a standard 4-20 mA output for plant protection logic. Its integrated Proximitor design eliminates the need for additional enclosures, and non-isolated PROX OUT/COM terminals plus a coax connector provide raw dynamic data for advanced diagnostics. The unit features sealed zero/span potentiometers beneath the label for easy loop trimming, a test-input pin for verifying loop current on-site, and a Not-OK/signal-defeat circuit that clamps the output if the probe or cable fails, preventing false trips. It comes with DIN-rail clips and bulkhead screws, allowing flexible installation wherever panel space is available.

Advantages
The Bently Nevada 990-10-XX-01-00 MOD:165353-01 Vibration Transmitter is designed for OEMs seeking a single 4-20 mA vibration output directly into their control systems. It converts signals from a 3300 NSv probe into peak-to-peak vibration values in engineering units, supporting plant protection logic without additional signal conditioning. Its integrated Proximitor eliminates the need for an extra enclosure, while non-isolated PROX OUT/COM terminals and a coax connector provide raw dynamic data for advanced diagnostics. Sealed zero/span potentiometers and a built-in test-input pin enable fast calibration and verification on-site, reducing commissioning time and ensuring reliable operation under continuous industrial conditions.
Industrial Applications
The 990 Vibration Transmitter is ideal for monitoring small rotating machinery such as compressors, pumps, and motors. By providing a 4-20 mA output proportional to vibration amplitude, it allows integration into existing plant controllers for early fault detection and protection. Its high-frequency response (5 Hz to 6 kHz) ensures accurate monitoring of critical shaft movement, while the compact two-wire design simplifies wiring in control panels, making it suitable for OEM equipment and custom-built systems.
