Product Overview

The Bently Nevada 990-05-XX-03-CN Vibration Transmitter is a precision-engineered device designed for the continuous monitoring of radial vibration in industrial rotating machinery. As a critical component in the 990 Series, this transmitter provides an efficient, cost-effective solution for monitoring equipment that does not require the complexity of a full-scale rack-based system. By converting proximity probe signals directly into a proportional 4-20 mA signal, the 990-05-XX-03-CN integrates seamlessly into PLC or DCS control systems, providing essential mechanical health data for site operators.

With built-in certifications including CSA Division 2, ATEX, and ABS maritime approval, this transmitter is uniquely suited for hazardous and offshore environments. When you buy this transmitter, you are investing in the long-term reliability of your assets, ensuring early detection of bearing wear, rotor imbalance, and shaft misalignment.

Key Features

• Simplified Integration: Direct 4-20 mA output allows for easy connection to existing automation infrastructure without additional rack space.

• Wide-Range Measurement: The 0-5 mils pp (0-125 µm pp) range offers high-fidelity monitoring for a variety of medium-to-large machinery.

• Hazardous Area Certified: Robust construction compliant with CSA Div 2 and ATEX standards for safe operation in explosive atmospheres.

• Maritime Approved: ABS certification makes this an ideal choice for marine and offshore power generation applications.

• Compact Footprint: Includes DIN clips and screws for quick, stable mounting in cramped cabinets or control enclosures.

Technical Specifications

Model Configuration Explanation

The model number 990-05-XX-03-CN is highly descriptive:

• 990: Represents the base Vibration Transmitter series.

• 05: Refers to the full-scale range of 0-5 mils pp (0-125 µm pp), covering the most common industrial vibration thresholds.

• XX: Customization code (varies by application).

• 03: Specifies the included mounting hardware (DIN clips and screws).

• CN: Indicates full international hazardous area and marine certifications (CSA, ATEX, ABS).

Typical Applications

• General Purpose Machinery: Continuous monitoring for pumps, fans, and blowers.

• Power Generation: Speed and vibration tracking for auxiliary power equipment.

• Offshore Platforms: Reliable vibration monitoring for maritime pump sets and motor-drive systems.

• Petrochemical Industry: Safety monitoring in explosive environments where ATEX Zone 2 compliance is mandatory.

• Manufacturing: Long-term maintenance tracking for critical gearbox and motor bearings.

System Compatibility

The 990-05-XX-03-CN is designed to function as an independent, "transmitter-style" device. It is fully compatible with standard Bently Nevada proximity probe systems. By outputting a standard analog current loop, it bypasses the need for complex rack-mount instrumentation, making it the perfect upgrade for plants transitioning to digital control systems (DCS).

Installation Guidelines

1. Environmental Check: Ensure the installation area matches the ATEX/CSA hazardous area ratings provided in the datasheet.

2. Mounting: Utilize the provided DIN clips for installation on standard 35mm DIN rail for optimal alignment and vibration resistance.

3. Wiring: Connect the 4-20 mA loop to your PLC/DCS input card. Use shielded, twisted-pair cabling to prevent EMI.

4. Sensor Calibration: Ensure the proximity probe connected to the transmitter is properly gapped according to the machine's technical manual.

5. Validation: Use the 4-20 mA signal loop to verify that the transmitter output matches your reference handheld vibration monitor.
