Bently Nevada 200350-09-00-CN Accelerometer: High-Performance Vibration Sensor

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 200350-09-00-CN accelerometer delivers reliable, accurate data. This 200350 series sensor provides a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, making it suitable for critical rotating equipment monitoring. Its compact design (height 1.65 inches, weight 0.051 kg) allows installation in tight spaces.

Technical Specifications Breakdown

The 200350-09-00-CN offers a frequency range of 30-600,000 cpm (0.5-10,000 Hz) with ±3 dB flatness, covering low-speed to high-speed machinery. The ceramic shear sensing element ensures excellent stability and transverse sensitivity ≤7%. Output bias voltage sits between 8 to 12 VDC, while excitation voltage ranges from 18 to 28 VDC with constant current excitation of 2 to 20 mA. The discharge time constant is ≥0.3 seconds, and output impedance is less than 150 ohms. Electrical isolation from the case exceeds 108 ohms, providing robust noise immunity.

Broadband electrical noise (1-10 kHz) is only 350 μg (3,434 μm/s²), ensuring clean signals even in electrically noisy environments. The sensor withstands shock survivability of 5,000 g pk and operates in 100% relative humidity (condensing, non-submerged). Its IP68 enclosure rating guarantees protection against dust and prolonged water immersion.

Industry Applications

This accelerometer excels in predictive maintenance programs for pumps, fans, compressors, and motors. Its wide temperature range (-65°F to +250°F / -54°C to +121°C) suits outdoor and process industry installations. The welded hermetic stainless steel housing and 2-pin Mil-C-5015 top connector resist corrosion and moisture, making it ideal for oil and gas, chemical, and power generation environments.

Installation & Setup Guidance

Mount using the 1/4-28 female thread with a torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The 09 mounting stud option means no mounting stud is included; use appropriate stud or adhesive mounting per application. Allow 2.0 seconds settling time (within 1% of bias) after power-up before taking measurements. Ensure excitation voltage is between 18 and 28 VDC with constant current between 2 and 20 mA.

Maintenance & Reliability

Routine inspection of the cable and connector integrity is recommended. The IP68 rating and welded hermetic seal minimize environmental degradation. Periodic verification of output bias voltage (8-12 VDC) and sensitivity (100 mV/g ±20%) ensures continued accuracy. No internal disassembly is required or advised.

Selection Guide & Purchasing Advice

When ordering, confirm the agency approvals option: CN for country-specific. The tolerance code 00 indicates 100 mV/g ±20%. Verify that your monitoring system accepts the 2-pin Mil-C-5015 connector.
