Product Overview

The Bently Nevada 200350-12-00-CN is a high-performance piezoelectric accelerometer designed for the precise measurement of high-frequency vibration in rotating machinery. As a key component of a comprehensive machinery protection system, this sensor converts mechanical acceleration into a proportional electrical signal. It is particularly effective for monitoring casing vibration on machines with rolling-element bearings, where high-frequency "noise" from bearing defects or gear mesh issues must be captured and analyzed.

The "CN" designation indicates a version configured for regional regulatory compliance while maintaining the elite engineering standards of the global Bently Nevada 200350 series. This sensor is typically used in conjunction with a vibration monitor (such as the 3500/42M) to provide plant operators with real-time data for trend analysis and emergency shutdown protection.

Key Technical Characteristics

The 200350 series is engineered to deliver stable, low-noise data in the presence of significant electromagnetic interference and extreme mechanical stress.

• Piezoelectric Precision: Utilizes a shear-mode crystal design that provides excellent immunity to base strain and thermal transients, ensuring that the output signal reflects actual vibration rather than environmental noise.

• Broad Frequency Response: Capable of capturing a wide spectrum of vibration data, making it suitable for detecting early-stage bearing wear and complex gear mesh frequencies.

• Integral Signal Conditioning: The internal electronics provide a low-impedance voltage output, allowing the signal to be transmitted over long cable runs without significant loss or susceptibility to interference.

• Ruggedized Housing: Encased in a hermetically sealed stainless steel body, the 200350-12-00-CN is built to resist corrosion, moisture, and chemical exposure common in industrial plants.

• TSI Integration: Designed for seamless connectivity with Turbine Supervisory Instrumentation (TSI), facilitating advanced diagnostics like spectrum analysis and waveform processing.
