Bently Nevada 200350-01-00-CN Accelerometer: 100 mV/g Vibration Sensor

Product Introduction

When unexpected machine vibrations threaten uptime, the Bently Nevada 200350-01-00-CN accelerometer provides precise, reliable data for condition monitoring. This 200350 series sensor delivers a sensitivity of 100 mV/g ±20%, making it a trusted choice for maintenance engineers who demand consistent performance in harsh environments. Manufactured in the U.S.A., this accelerometer is built for long-term service.

Technical Specifications Breakdown

The 200350-01-00-CN offers a measurement range of ±50g, covering a wide spectrum of vibration amplitudes. Its frequency response spans 30–600,000 cpm (0.5–10,000 Hz) within ±3 dB, ensuring accurate readings from slow-speed to high-speed machinery. The output bias voltage sits between 8 and 12 VDC, while the excitation voltage range is 18 to 28 VDC with a constant current excitation of 2 to 20 mA. These parameters integrate seamlessly with standard data collectors and monitoring systems. The sensor's broadband electrical noise is exceptionally low at 350 μg (3,434 μm/s²) over 1–10 kHz, preserving signal integrity even in electrically noisy plant floors. Output impedance is less than 150 ohms, and the discharge time constant is ≥0.3 seconds.

Industry Applications

Maintenance engineers rely on the 200350-01-00-CN for rotating equipment such as pumps, motors, fans, and compressors. Its ceramic shear sensing element and welded hermetic stainless steel housing withstand temperatures from -65°F to +250°F (-54°C to +121°C) and 100% relative humidity (condensing, non-submerged). With an IP68 enclosure rating, this accelerometer performs reliably in washdown areas and dusty environments. The 2-pin Mil-C-5015 top connector simplifies cabling, while the ¼-28 to M6 x 1.00 stainless steel mounting stud ensures secure attachment. For predictive maintenance programs, the ±1% amplitude linearity and ≤7% transverse sensitivity guarantee trustworthy data for trend analysis.

Installation & Setup Guidance

Mount the 200350-01-00-CN using the provided ¼-28 female thread. Apply a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to ensure proper coupling without over-tightening. The sensor's hex size is 11/16" (1.8 cm), and its height is 1.65" (4.24 cm). After installation, allow a settling time of 2.0 seconds (within 1% of bias) before taking measurements. Verify electrical isolation greater than 10⁸ ohms from case to ground. For best results, mount on a clean, flat surface and use a thin layer of coupling grease if recommended by your system manual.

Maintenance & Reliability

This accelerometer requires minimal routine care. Periodically inspect the cable and connector for damage, especially in high-vibration or corrosive areas. The welded hermetic seal protects the internal ceramic element from moisture and contaminants, supporting long service intervals. Because the sensor is rated for 5,000 g pk shock survivability, it withstands occasional impacts during installation or machine events. For maintenance engineers focused on reducing downtime, the 200350-01-00-CN offers stable bias voltage and low noise over its operating life, reducing false alarms and unplanned inspections.

Selection Guide & Purchasing Advice

Before ordering the 200350-01-00-CN, confirm that your monitoring system accepts a 100 mV/g sensitivity with ±20% tolerance and requires constant current excitation between 2 and 20 mA. Verify the agency approvals option CN matches your regional requirements.
