Bently Nevada 200350-09-00-01 Accelerometer: High-Performance Vibration Sensor

Product Overview

When machinery vibration threatens uptime and safety, the Bently Nevada 200350-09-00-01 accelerometer provides reliable, accurate data for condition monitoring. This 200350 series sensor is designed for demanding industrial environments where precise vibration measurement is critical to preventing catastrophic failures.

Technical Specifications

The 200350-09-00-01 offers a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%), ensuring consistent output across its measurement range of ±50g. Its frequency response spans 30 to 600,000 cpm (0.5–10,000 Hz), covering both low-speed and high-speed rotating machinery. Transverse sensitivity is ≤7%, minimizing cross-axis errors. Amplitude linearity is ±1%, providing accurate representation of vibration levels. The mounted resonant frequency reaches 1500 kcpm (25 kHz), allowing detection of high-frequency events. Broadband electrical noise (1–10 kHz) is only 350 μg (3,434 μm/s²), preserving signal integrity. Output bias voltage ranges from 8 to 12 VDC, with an excitation voltage of 18 to 28 VDC and constant current excitation of 2 to 20 mA. Settling time (within 1% of bias) is 2.0 seconds, and output impedance is less than 150 ohms. Discharge time constant is ≥0.3 seconds, and electrical isolation from case exceeds 108 ohms.

Industry Applications

In rotating equipment monitoring—such as pumps, fans, compressors, and turbines—the 200350-09-00-01 excels at detecting imbalance, misalignment, and bearing wear. Its wide frequency range and ±50g measurement capability make it suitable for both normal operation and transient events. For example, in a petrochemical plant, this accelerometer mounted on a critical pump can provide early warning of developing faults, reducing unplanned downtime. The IP68 enclosure rating and 100% relative humidity tolerance allow deployment in washdown areas or outdoor installations without concern for moisture ingress.

Installation & Setup Guidance

Mount the 200350-09-00-01 using the 1/4-28 female thread with a maximum mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The hex size is 11/16” (1.8 cm), and the height is 1.65” (4.24 cm). Use the 2-pin Mil-C-5015 connector located at the top for electrical connection. Ensure the mounting surface is clean, flat, and free of debris to achieve optimal coupling. Apply a thin layer of coupling grease if recommended by the manufacturer. Verify that the excitation voltage is within 18 to 28 VDC and constant current is between 2 and 20 mA before powering the sensor.

Maintenance & Reliability

Routine inspection of the cable and connector for damage is recommended, especially in high-vibration or corrosive environments. The welded hermetic seal and stainless steel housing provide excellent protection against contaminants. The ceramic shear sensing element offers long-term stability and resistance to thermal effects. Given the harsh operating temperature range of -65°F to +250 °F (-54°C to +121 °C), the sensor can withstand extreme conditions. Shock survivability of 5,000 g pk ensures robustness during installation or incidental impacts. Periodic verification of sensitivity and bias voltage can confirm continued accuracy.

Selection Guide & Purchasing Advice

When selecting the 200350-09-00-01, verify that your monitoring system accepts a 100 mV/g sensitivity and requires CSA, ATEX, and IECEx agency approvals. This variant includes no mounting stud (option 09) and tolerance code 00. For applications needing different sensitivity or mounting options, consult the 200350 series datasheet.
