Product Overview
When unexpected machinery failures disrupt operations, the Bently Nevada 200350-01-00-CN 200350 Accelerometer delivers reliable vibration data to help prevent downtime. This rugged sensor is designed for demanding industrial environments where accuracy and durability are critical.
Technical Specifications
The 200350-01-00-CN offers a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%), ensuring precise vibration measurements across a frequency range of 30-600,000 cpm (0.5-10,000 Hz) within ±3 dB. Its measurement range of ±50 g covers a wide spectrum of machinery conditions, while transverse sensitivity is ≤7% for minimal cross-axis errors.
Amplitude linearity holds within ±1%, and the mounted resonant frequency reaches 1500 kcpm (25 kHz) for high-frequency response. Broadband electrical noise is only 350 μg (3,434 μm/s²) from 1-10 kHz, ensuring clean signals. Output bias voltage is 8 to 12 VDC, with excitation voltage of 18 to 28 VDC and constant current excitation of 2 to 20 mA. Settling time is 2.0 seconds within 1% of bias, output impedance is <150 ohms, and discharge time constant is ≥0.3 seconds. Electrical isolation from case exceeds 10⁸ ohms.
Industry Applications
In rotating machinery such as pumps, compressors, and turbines, the 200350-01-00-CN provides critical vibration data for predictive maintenance. Its IP68 enclosure rating and 100% relative humidity tolerance (condensing, non-submerged) make it suitable for wet or washdown environments. The stainless steel housing and welded hermetic sealing protect against corrosion and moisture ingress, extending service life in harsh conditions.
Installation & Setup Guidance
Mount the 200350-01-00-CN using the 1/4-28 female thread with a maximum mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The mounting stud option 01 is ¼-28 to M6 x 1.00 stainless steel. Ensure the mounting surface is clean and flat for optimal coupling. The 2-pin Mil-C-5015 electrical connector is positioned at the top for easy cable routing. Allow 2.0 seconds settling time after power-up before taking measurements.
Maintenance & Reliability
Periodically inspect the cable and connector for damage, especially in high-vibration or corrosive areas. The ceramic shear sensing element and welded hermetic seal require no routine maintenance, but verify the mounting torque annually. The 200350-01-00-CN can survive shocks up to 5,000 g pk, ensuring robust performance in demanding applications.
Compatibility & Integration
This accelerometer works with most vibration monitoring systems that accept IEPE-type sensors with constant current excitation of 2 to 20 mA. Its 100 mV/g sensitivity is a standard output level compatible with many data collectors and online monitoring systems. The top-exit connector simplifies integration into existing installations.
Selection Guide & Purchasing Advice
Before purchasing, verify that your monitoring system supports the 200350-01-00-CN's excitation voltage (18-28 VDC) and output bias voltage (8-12 VDC). The CN agency approval option indicates country-specific certifications. SpareTechPLC stocks this Bently Nevada accelerometer and can assist with compatibility questions.
