Features:
- Provides a loop-powered 4–20 mA vibration output derived from proximity probe input for simplified monitoring integration.
- Includes integrated signal conditioning with adjustable zero/span and built-in diagnostic access via PROX OUT interface.
- Supports harsh environments with sealed construction, wide temperature range, and multiple industrial certifications.
The Bently Nevada 990-05-50-02-05 is designed for industrial systems where simplified vibration monitoring is required without full diagnostic complexity. The Bently Nevada 990-05-50-02-05 operates as a two-wire loop-powered device, making it suitable for compact machine installations where wiring and space are limited. It processes vibration signals from compatible proximity probes and converts them into standardized output values. This design allows control systems to receive stable vibration feedback for basic protection functions.
In applications where centrifugal compressors or small rotating machines are used, the Bently Nevada 990-05-50-02-05 provides a practical signal conversion solution. The system supports peak-to-peak vibration representation and delivers a proportional 4–20 mA signal to downstream control equipment. It also includes adjustable configuration elements such as zero and span potentiometers for loop calibration. The integrated design reduces the need for external signal conditioning modules.
The Bently Nevada 990-05-50-02-05 is built for environments requiring reliable operation under varying conditions, including humidity and temperature fluctuations. Its construction supports both bulkhead and DIN-rail installation methods for flexible mounting. The unit also provides diagnostic signal access through its PROX OUT interface for maintenance and verification purposes. Overall, it serves as a compact vibration transmission solution for OEM and industrial machinery systems.
The 990-05-50-02-05 Bently Nevada Vibration Transmitter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Product Family 990-04-50-02-05,990-08-50-02-05,990-10-50-02-05
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- System Simplification: Direct 4-20mA signal output eliminates the need for intermediate converters for connection to PLC or DCS systems, significantly reducing system complexity.
- Status Indication: Features a "non-OK" status detection function. When a probe or cable malfunctions, the current automatically drops below 3.6mA, facilitating system identification and preventing false alarms.
- Isolation Protection: The design incorporates power and signal isolation mechanisms, effectively suppressing common industrial ground loop interference and electromagnetic noise, ensuring data accuracy.
- Quick Diagnostics: The enclosure provides a dedicated buffered output connector, allowing maintenance personnel to directly connect to portable analyzers for spectrum diagnostics.
- Flexible Installation: A compact DIN rail mounting design supports high-density layouts, greatly saving internal control cabinet space.
- Convenient Commissioning: Supports on-site adjustment of "zero" and "full scale" positions, compensating for signal offsets caused by mechanical installation errors or material differences.
- Environmental Adaptability: Features a robust, sealed housing design, enabling long-term stable operation in industrial indoor environments with oil mist, high humidity, or corrosive gases.
- Electrical Compatibility: Its rationally distributed terminal blocks support standard industrial wiring and exhibit strong tolerance to fluctuations in external DC power supply voltage.
- Centrifugal Machinery: Used for real-time monitoring of radial vibration (shaft vibration) in rotating equipment such as centrifugal pumps, fans, and motors.
- Critical Equipment Protection: Provides economical and reliable vibration shutdown protection for small and medium-sized rotating machines that lack dedicated unit protection systems (such as the 3500 system).
- Remote Monitoring: Suitable for geographically dispersed pump stations or unattended stations, enabling long-distance monitoring via a 4-20mA signal.
- Shaft Displacement Measurement: Configurable for monitoring changes in axial displacement of rotating shafts caused by load fluctuations or thrust bearing wear.
