Solving Vibration Monitoring Challenges in Harsh Industrial Environments
When rotating machinery begins to exhibit subtle vibrations, engineers face a critical challenge: detecting these early signs of wear before they escalate into costly failures. In environments where moisture, temperature extremes, and physical shocks are daily realities, standard sensors often fall short. The Bently Nevada 200350-12-00-CN accelerometer is engineered to meet this exact need, delivering reliable vibration data in the most demanding conditions.
Introducing the 200350-12-00-CN Accelerometer
Part of the 200350&200355 series, the 200350-12-00-CN is a high-performance accelerometer from Bently Nevada, a trusted name in industrial monitoring. This sensor is designed for permanent installation on critical machinery, providing continuous vibration measurement to support predictive maintenance programs. Manufactured in the U.S.A., it combines rugged construction with precise sensing capabilities.
Technical Specifications and Performance
The 200350-12-00-CN offers a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%), ensuring accurate vibration detection across a wide frequency range of 30-600,000 cpm (0.5-10,000 Hz). With a measurement range of ±50g, it can handle both normal operating vibrations and occasional high-amplitude events. The sensor features a mounted resonant frequency of 1500 kcpm (25 kHz), which minimizes interference from structural resonances.
Broadband electrical noise is exceptionally low at 350 μg (3,434 μm/s²) over 1-10 kHz, preserving signal integrity even in electrically noisy environments. The output bias voltage is 8 to 12 VDC, and the sensor requires an excitation voltage of 18 to 28 VDC with a constant current excitation of 2 to 20 mA. Its settling time is 2.0 seconds, allowing quick stabilization after power-up.
Built for Extreme Conditions
The 200350-12-00-CN is rated for an operating temperature range of -65°F to +250 ºF (-54°C to +121 ºC), making it suitable for both freezing and high-heat applications. It can survive shocks up to 5,000 g pk, ensuring resilience against sudden impacts. The enclosure rating is IP68, meaning it is fully protected against dust and can withstand continuous immersion in water under specified conditions. Additionally, it operates in 100% relative humidity, condensing, non-submerged environments.
Real-World Application Example
In a typical chemical processing plant, pumps and compressors operate continuously under high temperatures and humidity. The 200350-12-00-CN, with its IP68 rating and wide temperature tolerance, can be mounted directly on these machines to monitor vibration trends. Early detection of bearing wear or imbalance allows maintenance teams to schedule repairs during planned downtime, avoiding unexpected production halts.
