200350-02-00-CN Bently Nevada Vibration Transducer

Product Overview

The 200350-02-00-CN is a versatile and durable industrial accelerometer designed by Bently Nevada for continuous vibration monitoring. Engineered to provide reliable data for predictive maintenance programs, this sensor is optimized for high-speed assets such as compressors and pumps where precision is paramount. By utilizing a 100 mV/g sensitivity scale, it translates mechanical vibration into clear electrical signals, allowing operators to detect early signs of bearing wear or rotor instability before they escalate into costly mechanical failures.

Technical Configuration

The 200350-02-00-CN features a specific hardware stack tailored for international industrial standards. The "02" configuration specifies an M8x1.25 Beryllium Copper (BeCu) mounting stud, known for its superior fatigue resistance and excellent acoustic coupling. The "00" designation indicates a standard ±20% tolerance for the 100 mV/g output, providing a balanced cost-to-performance ratio for general-purpose monitoring. Additionally, the "CN" suffix ensures the unit meets regional compliance standards, making it an ideal choice for global projects requiring localized certification.

Technical Specifications

Installation & Maintenance Guide

To maximize the frequency response of the 200350-02-00-CN, the sensor should be mounted on a flat, machined surface. The M8x1.25 BeCu stud must be tightened to the recommended torque to ensure rigid coupling. Improper mounting can lead to signal resonance and false high-frequency readings. The integrated 2-meter coaxial cable is EMI/RFI shielded; however, it should still be routed away from high-voltage motor leads to maintain a high signal-to-noise ratio. Periodic inspection of the IP67-rated connector is advised in high-moisture environments.

Engineering Advantages

The 200350-02-00-CN offers exceptional phase response (±3° from 2 Hz to 5 kHz), which is critical for accurate balancing and diagnostic analysis. Its 304 stainless steel housing and 5000g peak shock resistance ensure it survives the transient conditions of heavy-duty industrial machinery. Furthermore, the 0.5% linearity within the primary monitoring band (50-1000 Hz) provides the high-fidelity data required by advanced vibration analyzers for detecting subtle mechanical changes over long operational periods.

Technical FAQs

Q1: What does the CN classification represent?
A1: The CN classification indicates that the accelerometer has undergone specific regional testing and certification to meet local safety and industrial compliance standards.

Q2: Can this sensor be used for low-speed machinery?
A2: While it has a 5 Hz response, it is primarily optimized for the mid-to-high frequency ranges found in rotating turbines and compressors. For ultra-low-speed assets, a velocity sensor may be more appropriate.

Q3: Why is Beryllium Copper used for the mounting stud?
A3: BeCu provides a combination of high strength and excellent fatigue resistance, ensuring the sensor remains securely fastened even under constant high-frequency vibration.
