Bently Nevada 200350-12-00-CN Accelerometer: Precision Vibration Sensor

Product Overview

When unplanned downtime threatens production targets, the Bently Nevada 200350-12-00-CN accelerometer provides the reliable vibration data you need for effective condition monitoring. This 200350 series sensor delivers precise measurements across a broad frequency range, helping maintenance teams detect early signs of bearing wear, imbalance, or misalignment before they escalate into costly failures.

The 200350-12-00-CN is designed for demanding industrial environments. With a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, it captures both subtle vibrations and strong shock events. Its IP68 enclosure rating ensures reliable operation in wet, dusty, or condensing conditions, making it suitable for applications from rotating machinery to structural health monitoring.

Technical Specifications Breakdown

Understanding key parameters helps you select the right sensor for your application. The 200350-12-00-CN offers the following critical specifications:

Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%) – provides consistent output for accurate vibration amplitude measurement.

Frequency Range: 30-600,000 cpm (0.5-10,000 Hz) ±3 dB – covers low-speed to high-speed machinery monitoring needs.

Measurement Range: ±50g – suitable for normal vibration levels and occasional shock events.

Operating Temperature: -65°F to +250°F (-54°C to +121°C) – ensures performance in extreme thermal environments.

Enclosure Rating: IP68 – withstands continuous immersion in water and dust ingress.

Additional specs include a mounted resonant frequency of 1500 kcpm (25 kHz), broadband electrical noise of 350 μg (3,434 μm/s²) from 1-10 kHz, and output bias voltage of 8 to 12 VDC. The sensor requires 18 to 28 VDC excitation with constant current of 2 to 20 mA.

Industry Applications

The 200350-12-00-CN excels in predictive maintenance programs across multiple sectors:

Oil & Gas: Monitor pumps, compressors, and turbines in refineries and pipelines. The IP68 rating allows installation in washdown areas or outdoor locations exposed to rain.

Power Generation: Track vibration on gas turbines, steam turbines, and generators. The wide frequency range captures both low-speed rotor dynamics and high-speed blade pass frequencies.

Manufacturing: Protect critical assets like fans, motors, and gearboxes in automotive or food processing plants. The stainless steel housing and welded hermetic seal resist corrosion from cleaning chemicals.

Installation & Setup Guidance

Proper mounting is essential for accurate vibration data. The 200350-12-00-CN uses an M8x1.25 adhesive stud mount (option 12). Follow these steps:

Clean the mounting surface thoroughly to remove paint, rust, or debris.

Apply the adhesive stud mount to a flat, smooth area on the machine casing.

Tighten the sensor to 2 to 5 ft-lb (2.7 to 6.8 N-m) using the 11/16" (1.8 cm) hex on the housing.

Connect the 2-pin Mil-C-5015 connector and verify output bias voltage (8-12 VDC) before powering the system.

For best frequency response, mount the sensor directly on the bearing housing or as close to the vibration source as possible.

Maintenance & Reliability

The 200350-12-00-CN requires minimal maintenance due to its robust design. The ceramic sensing element and shear geometry provide long-term stability. The welded hermetic seal prevents moisture ingress, even in 100% condensing humidity.

Periodically inspect the cable and connector for damage. Verify the output bias voltage during routine system checks – a shift outside 8-12 VDC may indicate sensor degradation. The sensor can survive shocks up to 5,000 g pk, making it resilient in harsh environments.

Selection Guide & Purchasing Advice

When ordering the 200350-12-00-CN, confirm the mounting stud option (12 = M8x1.25 adhesive stud mount) and agency approvals (CN = country specific). This model does not include a cable – order separately based on your required length and connector type.
