990-10-XX-02-00 | Bently Nevada 990 Series Vibration Transmitter

Product Overview

The Bently Nevada 990-10-XX-02-00 acts as a high-performance signal conditioner designed for radial vibration monitoring on rotating machinery. This transmitter specifically interfaces with 3300 NSv (Near Side view) proximity probes, making it the primary choice for applications with small shaft diameters or tight mounting clearances. We supply this unit as 100% Brand New and Original in its factory-sealed packaging, ensuring long-term stability and compliance with original equipment manufacturer (OEM) standards.

Part Number Breakdown

The 990-10-XX-02-00 configuration utilizes a modular selection code to define measurement range and physical installation hardware:

Technical Specifications

The 990-10-XX-02-00 delivers precise 4-20 mA data via a simplified 2-wire loop-powered architecture:

• Input Compatibility: Connects directly to 3300 NSv proximity probes

• Output Signal: 4 to 20 mA analog (proportional to vibration levels)

• Frequency Response: 5 Hz to 6,000 Hz (300 to 360,000 cpm)

• Power Supply: 17.5 to 30 Vdc (2-wire loop powered)

• System Lengths: Available in 5.0m and 7.0m electrical configurations

• Condition: Brand New, original factory packing

Engineering Advantages

• Optimized for Restricted Spaces: Unlike standard proximity systems, this transmitter works with the 3300 NSv series. The NSv technology allows for accurate vibration measurement on shafts as small as 50 mm (2 inches) where standard sensors encounter side-view interference.

• Direct Control System Interface: The unit eliminates the need for expensive rack-mounted monitors. It outputs a standard 4-20 mA signal that communicates directly with your PLC or DCS, reducing hardware footprint and total installation cost.

• Flexible Bulkhead Mounting: The "02" mounting option provides a sturdy bulkhead plate. This allows engineers to mount the transmitter inside local junction boxes or directly onto machine frames where DIN-rail space is unavailable.

• High-Frequency Precision: The 5 Hz to 6,000 Hz response range ensures the transmitter captures both low-speed shaft unbalance and high-frequency harmonic content, providing a comprehensive view of machine health.

FAQs

• Can I use this with a standard 3300 XL 8mm probe? No. The 990-10-XX-02-00 is specifically calibrated for the 3300 NSv probe series. Using it with a standard 8mm probe will cause significant measurement errors and non-linear outputs.

• How do I choose between the 5m and 7m "XX" option? The "XX" must match the total electrical length of your probe and extension cable combined. A mismatch between the transmitter calibration and the physical cable length will compromise data accuracy.

• Does this transmitter provide a raw signal for diagnostics? Yes. The unit includes a BNC connector that provides a buffered raw vibration signal. Reliability technicians can connect portable analyzers to this port for detailed waveform analysis without interrupting the 4-20 mA protection loop.

• Is this a refurbished or used component? Absolutely not. We deliver only Brand New and Original Bently Nevada hardware. Each unit includes the factory serial number and the standard 12-month manufacturer warranty.
