Bently Nevada 200355-02-00-CN 200350 Accelerometer: High-Performance Vibration Sensor

Introduction

When unexpected machinery vibrations threaten production uptime, how do you ensure early detection without false alarms? The Bently Nevada 200355-02-00-CN 200350 accelerometer delivers reliable, high-fidelity vibration data for critical rotating equipment. This industrial-grade sensor combines rugged construction with precise measurement capabilities, making it a trusted choice for predictive maintenance programs.

Technical Specifications

The 200355-02-00-CN features a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%) and a frequency range of 30 to 600,000 cpm (0.5 to 10,000 Hz). It measures vibration up to ±50 g with transverse sensitivity ≤7%. Amplitude linearity is ±1%, and the mounted resonant frequency reaches 1500 kcpm (25 kHz). Broadband electrical noise from 1 to 10 kHz is only 350 μg (3,434 μm/s²). Output bias voltage ranges from 8 to 12 VDC, requiring an excitation voltage of 18 to 28 VDC with constant current excitation of 2 to 20 mA. Settling time (within 1% of bias) is 2.0 seconds, output impedance is less than 150 ohms, discharge time constant is ≥0.3 seconds, and electrical isolation from the case exceeds 108 ohms. Operating temperature range is -65°F to +250°F (-54°C to +121°C). Shock survivability is 5,000 g peak. It withstands 100% relative humidity, condensing, non-submerged conditions, and carries an IP68 enclosure rating. The mounting thread is 1/4-28 female with a mounting 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, and sealing is welded hermetic. Electrical connection uses a 2-pin Mil-C-5015 connector in top position. The hex size is 11/16” (1.8 cm), height is 1.65” (4.24 cm), and weight is 0.051 kg.

Industry Applications

This accelerometer excels in monitoring rotating machinery such as pumps, compressors, turbines, and fans in oil and gas, power generation, and manufacturing plants. Its wide frequency range captures both low-speed and high-speed vibrations, enabling early bearing fault detection and imbalance analysis. The IP68 rating allows deployment in washdown environments or outdoor installations exposed to rain and condensation. For example, a petrochemical facility can use the 200355-02-00-CN to continuously monitor critical pump vibration, reducing unplanned downtime and extending equipment life.

Installation & Setup Guidance

Mount the accelerometer using the 1/4-28 female thread with a mounting stud option of ¼-28 to M8 x 1.25 BeCu. Apply the specified mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to ensure proper coupling without damaging the sensor. Use the 2-pin Mil-C-5015 connector for electrical connections. Verify the excitation voltage (18 to 28 VDC) and constant current (2 to 20 mA) from your monitoring system. Allow 2.0 seconds settling time after power-up before taking critical measurements. For best accuracy, mount the sensor on a clean, flat surface and avoid excessive cable movement that could introduce noise.

Maintenance & Reliability

The welded hermetic stainless steel construction and ceramic sensing element provide long-term stability in harsh conditions. No routine recalibration is needed under normal use, but periodic verification of output bias voltage (8 to 12 VDC) can confirm sensor health. Inspect the connector and cable for damage annually. The IP68 rating ensures reliable operation even in condensing humidity. With shock survivability of 5,000 g peak, this accelerometer withstands occasional mechanical shocks without performance degradation.

Selection Guide & Purchasing Advice

When ordering the Bently Nevada 200355-02-00-CN, verify the agency approvals option (CN for country-specific requirements) and mounting stud configuration (02 = ¼-28 to M8 x 1.25 BeCu). This model is ideal for applications requiring a sensitivity of 100 mV/g and a frequency range up to 10 kHz.
