Bently Nevada 200355-00-00-00 200350 Accelerometer Overview

Product Introduction

When monitoring machinery health in harsh environments, the Bently Nevada 200355-00-00-00 delivers reliable vibration data. This 200350 Accelerometer is designed for industrial applications where accuracy and durability matter. With a sensitivity of 100 mV/g ±20% and a frequency range of 30-600,000 cpm (0.5-10,000 Hz), it captures a wide spectrum of vibration signals. The unit weighs 0.051 kg and features a compact height of 1.65 inches (4.24 cm). Made in the U.S.A., this accelerometer is built for demanding conditions.

Technical Specifications Breakdown

Key parameters from the data sheet include:

Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%)

Frequency Range: 30-600,000 cpm (±3 dB) or 0.5-10,000 Hz

Measurement Range: ±50g

Broadband Electrical Noise (1-10 kHz): 350 μg (3,434 μm/s²)

Output Bias Voltage: 8 to 12 VDC

Excitation Voltage: 18 to 28 VDC

Constant Current Excitation: 2 to 20 mA

Operating Temperature Range: -65°F to +250°F (-54°C to +121°C)

Enclosure Rating: IP68

Weight: 0.051 kg

These specs ensure the sensor performs reliably in extreme temperatures and wet conditions. The ceramic shear sensing element provides stable output over time.

Industry Applications

This accelerometer suits rotating machinery monitoring in industries like oil and gas, power generation, and manufacturing. Use it on pumps, compressors, fans, and motors to detect imbalance, misalignment, or bearing faults. The wide frequency range covers both slow-speed and high-speed equipment. With IP68 protection, it operates in washdown environments or outdoor installations. The 100 mV/g sensitivity offers a good balance for general-purpose vibration monitoring.

Installation & Setup Guidance

Mount the sensor using the 1/4-28 female thread. Apply a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The mounting stud option (00 = ¼-28 SS with brass tip, 0.5 inches) provides a secure connection. Ensure the mounting surface is clean and flat for optimal coupling. Connect the 2-pin Mil-C-5015 connector to a compatible data acquisition system. Allow a settling time of 2.0 seconds (within 1% of bias) after power-up before taking measurements.

Selection Guide & Purchasing Advice

Before ordering the 200355-00-00-00, verify your system's excitation voltage (18-28 VDC) and constant current (2-20 mA). Confirm the output bias voltage range (8-12 VDC) matches your input module. This model has no agency approvals option (00 = No Approvals). For complete technical specifications, contact BluePLC Industrial.

Maintenance & Reliability

Periodically inspect the cable and connector for damage. Verify the output bias voltage during routine checks to ensure the sensor remains within spec. The welded hermetic sealing and stainless steel housing resist corrosion and moisture. The IP68 rating allows submersion in non-submerged condensing environments. Follow manufacturer guidelines for calibration intervals to maintain accuracy.

Compatibility & Integration

This accelerometer works with Bently Nevada monitoring systems and most industrial vibration data collectors. It outputs a standard analog signal compatible with PLCs, DCS, and standalone monitors. The 2-pin Mil-C-5015 connector is common in industrial settings. Ensure your system supports constant current excitation and can read the 8-12 VDC bias voltage.
