Bently Nevada 200355-09-00-00 200350 Accelerometer: High-Performance Vibration Sensor

Introduction

When vibration monitoring in harsh industrial environments demands reliable data, the Bently Nevada 200355-09-00-00 delivers. This 200350 series accelerometer provides accurate measurements across a wide frequency range, helping engineers detect early signs of mechanical wear. With its robust stainless steel construction and IP68 enclosure, it withstands extreme temperatures, humidity, and shock. For plant maintenance teams seeking consistent performance, this sensor offers a trusted solution.

Technical Specifications

The 200355-09-00-00 features a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%), ensuring precise vibration readings. Its frequency range spans 30–600,000 cpm (0.5–10,000 Hz), covering low-speed to high-speed machinery. The measurement range of ±50 g accommodates moderate vibration levels. Transverse sensitivity is ≤7%, minimizing cross-axis errors. Amplitude linearity remains within ±1% for accurate output. Mounted resonant frequency reaches 1500 kcpm (25 kHz), allowing high-frequency response. Broadband electrical noise from 1–10 kHz is only 350 μg (3,434 μm/s²), preserving signal clarity. Output bias voltage sits between 8 and 12 VDC, while excitation voltage ranges from 18 to 28 VDC. Constant current excitation requires 2 to 20 mA. Settling time (within 1% of bias) is 2.0 seconds. Output impedance is less than 150 ohms, and discharge time constant is ≥0.3 seconds. Electrical isolation (case) exceeds 108 ohms. Operating temperature spans -65°F to +250 ºF (-54°C to +121 ºC). Shock survivability is 5,000 g peak. Relative humidity tolerance is 100% condensing, non-submerged. Enclosure rating is IP68. Mounting thread is 1/4-28 female with maximum torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The sensing element is ceramic with shear geometry. Housing material is stainless steel with welded hermetic sealing. Electrical connector is a 2-pin Mil-C-5015 top-mounted.

Industry Applications

This accelerometer excels in rotating machinery monitoring, such as pumps, motors, fans, and compressors. In petrochemical plants, its IP68 rating and stainless steel housing resist corrosive atmospheres and washdown environments. For power generation turbines, the wide frequency range captures both low-speed imbalance and high-speed bearing faults. The ceramic shear sensing element provides stable output over temperature, making it suitable for outdoor installations in extreme climates.

Installation & Setup Guidance

Mount the 200355-09-00-00 using the 1/4-28 female thread. Apply a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) for optimal coupling. Ensure the mounting surface is clean and flat to avoid measurement errors. Connect the 2-pin Mil-C-5015 connector to a compatible data acquisition system. Use constant current excitation between 2 and 20 mA from an 18 to 28 VDC power source. Allow 2.0 seconds settling time after power-up before taking readings. Verify output bias voltage is within 8 to 12 VDC to confirm proper operation.

Maintenance & Reliability

Periodically inspect the accelerometer for physical damage, corrosion, or loose mounting. Check the connector and cable for wear, especially in high-vibration or wet environments. The welded hermetic seal protects the internal sensing element, but avoid submerging the device. Recalibrate annually or per manufacturer guidelines to maintain ±20% sensitivity tolerance. The stainless steel housing resists rust, extending service life in demanding conditions.

Selection Guide & Purchasing Advice

Before ordering the 200355-09-00-00, verify your system's excitation voltage and current requirements. This model has no mounting stud (option 09) and no agency approvals (option 00). Confirm the 1/4-28 female thread matches your mounting point. For complete technical specifications, contact BluePLC Industrial.
