Features:
- Interface Between the 3300 NSv Proximity Probe and Standard Industrial Control Systems
- Combines Proximity Probe Signal Conditioning with 4–20 mA Loop-Powered Output
- Operates in Conjunction with Bently Nevada 3300 NSv Probes and Extension Cables
The Bently Nevada 990-10-XX-01-00 MOD:165353-01 operates as a two-wire, loop-powered vibration transmitter, providing reliable 4–20 mA output proportional to vibration amplitude for direct integration with PLC or DCS control systems. It continuously processes signals from 3300 NSv proximity probes across a frequency range of 5 Hz to 6,000 Hz (+0, –3 dB) and converts these into a standard current signal distributed through the control loop to support continuous monitoring of rotating machinery. Seamless signal transmission is standard with the 990-10-XX-01-00 MOD:165353-01, and its built-in "Not OK/signal failure" protection circuit drives the output below 3.6 mA within 100 microseconds upon detection of probe faults or loose connections, preventing false control system actions and equipment damage.
The 990-10-XX-01-00 MOD:165353-01 provides essential vibration monitoring functions common to industrial rotating equipment, and is a critical component of the protection path, directly affecting the proper, normal operation of the overall machinery monitoring system. One 990-10-XX-01-00 MOD:165353-01 transmitter is required per monitoring point, and it is typically installed in a 35 mm DIN rail-mounted control panel for straightforward integration.
For advanced diagnostic applications, the 990-10-XX-01-00 MOD:165353-01 features a front-panel BNC connector that provides raw Proximitor dynamic signal output. In addition to standard 4–20 mA loop operation, this dynamic signal output enables connection to portable analyzers or permanent online diagnostic systems for vibration spectrum analysis. The 990-10-XX-01-00 MOD:165353-01 executes signal verification using the dedicated test input pin specified in the transmitter options.
The 990-10-XX-01-00 MOD:165353-01 Bently Nevada Vibration Transmitter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Bently Nevada 990-10-XX-01-00 MOD:165353-01 Vibration Transmitter Specs
General
- Manufacturer Bently Nevada
- Model 990-10-XX-01-00 MOD:165353-01
- Condition New Original ready stock
- Product Family 990-50-XX-01-00,990-70-XX-01-00
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.
- Fluid-Film Bearing Equipment: It is widely deployed to monitor the radial shaft vibration and shaft position of rotating machinery that relies on fluid-film or journal bearings.
- Centrifugal Air Compressors: The compact design makes it ideal for installation on small-footprint compressors and packaging skids where space is highly limited.
- Balance-of-Plant (BOP) Machinery: It provides standard vibration trending data for less critical rotating assets such as industrial pumps, fans, blowers, and electric motors.
- Direct Control System Interface: It is used to feed real-time vibration metrics straight into a Programmable Logic Controller (PLC) or Distributed Control System (DCS) via a standard 4-20 mA current loop.
- High Humidity and Moisture Protection: The transmitter features advanced potted construction, making it completely sealed and capable of operating in up to 100% condensing humidity.
- Temperature Tolerance: It functions reliably within a wide ambient temperature range, spanning from -35°C to +85°C (-31°F to +185°F).
- High Vibration Mounts: The standard configuration features a robust 35 mm DIN-rail clip, ensuring the transmitter remains securely locked in place even when exposed to heavy structural vibrations.
- Integrated Design: By combining a Proximitor sensor and a 4-20 mA transmitter into one module, it eliminates the need for separate signal-conditioning hardware and reduces overall field-wiring complexity.
- Dynamic Data Access: It includes a non-isolated "PROX OUT" terminal and a coaxial connector, allowing field technicians to hook up portable analyzers or oscilloscopes to view the raw vibration waveform without interrupting the control loop.
- False-Trip Prevention: Built-in "Not OK" and Signal Defeat circuitry monitors the health of the connected proximity probe, instantly clamping the output to prevent false alarms or emergency shutdowns if a sensor fault or cable break occurs.
- Simplified Calibration: The unit is equipped with a dedicated test input pin for running loop checks with a function generator, alongside non-interacting zero and span adjustments for straightforward field verification.
