Bently Nevada 200350-10-00-00 200350 Accelerometer: Precision Vibration Sensor

Product Introduction

When a critical rotating machine begins to show subtle vibration changes, the Bently Nevada 200350-10-00-00 accelerometer provides the precise data needed to diagnose developing faults before they cause unplanned downtime. This 200350 Accelerometer, manufactured in the U.S.A., is engineered for continuous vibration monitoring in demanding industrial environments. Its ceramic shear sensing element and welded hermetic stainless steel housing ensure long-term stability and reliability, even under extreme conditions.

Technical Specifications Breakdown

The 200350-10-00-00 delivers a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%), providing clear vibration signals across a frequency range of 30 to 600,000 cpm (0.5 to 10,000 Hz) within ±3 dB. With a measurement range of ±50g and transverse sensitivity of ≤7%, it accurately captures both low- and high-frequency vibration data. Amplitude linearity of ±1% ensures consistent performance across the measurement span. The mounted resonant frequency is 1500 kcpm (25 kHz), allowing detection of high-frequency events. Broadband electrical noise from 1 to 10 kHz is only 350 μg (3,434 μm/s²), preserving signal integrity. Output bias voltage is 8 to 12 VDC, and excitation voltage ranges from 18 to 28 VDC with constant current excitation of 2 to 20 mA. Settling time is 2.0 seconds (within 1% of bias), output impedance is less than 150 ohms, and discharge time constant is ≥0.3 seconds. Electrical isolation from case exceeds 108 ohms.

The accelerometer operates in temperatures from -65°F to +250 ºF (-54°C to +121 ºC) and survives shocks up to 5,000 g pk. It is rated for 100% relative humidity, condensing, non-submerged, and carries an IP68 enclosure rating. The mounting thread is 1/4-28 female with a recommended mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The hex size is 11/16” (1.8 cm), height is 1.65” (4.24 cm), and weight is 0.051 kg. The electrical connector is a 2-pin Mil-C-5015 top-mounted type.

Industry Applications

In the oil and gas industry, the 200350-10-00-00 is used on compressors, pumps, and turbines to detect bearing wear, imbalance, and misalignment. Its wide frequency range and high shock survivability make it suitable for reciprocating machinery and gearboxes. In power generation, it monitors steam and gas turbines, providing early warning of blade pass frequencies and other high-frequency phenomena. The IP68 rating allows installation in washdown areas or humid environments without concern for moisture ingress.

Installation & Setup Guidance

Mount the 200350-10-00-00 using the 1/4-28 adhesive stud mount (mounting stud option 10). Apply the recommended torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to ensure proper coupling and avoid mechanical damage. Connect the 2-pin Mil-C-5015 connector to a compatible data acquisition system. Verify the excitation voltage is between 18 and 28 VDC and constant current is set between 2 and 20 mA. Allow 2.0 seconds settling time after power-up before taking measurements.

Maintenance & Reliability

Regularly inspect the accelerometer for physical damage, corrosion, or loose mounting. Verify output bias voltage remains within 8 to 12 VDC as an indicator of sensor health. Clean the connector pins with a dry cloth if contamination is visible. The welded hermetic seal and stainless steel housing eliminate the need for internal maintenance. Periodic calibration checks against a known reference are recommended to ensure sensitivity remains within ±20% of 100 mV/g.

Selection Guide & Purchasing Advice

When selecting the 200350-10-00-00, confirm that the mounting thread matches your installation (1/4-28 female) and that the operating temperature range (-65°F to +250 ºF) covers your environment. This model has no agency approvals (option 00), so verify if your application requires specific certifications. The 100 mV/g sensitivity is ideal for general-purpose vibration monitoring; for lower amplitude signals, consider higher sensitivity options.
