Bently Nevada 200350-02-00-01 Accelerometer: 100 mV/g, CSA/ATEX/IECEx

Introduction

As industrial machinery has grown more complex, the need for precise, rugged vibration monitoring has never been greater. The Bently Nevada 200350-02-00-01 accelerometer represents a key evolution in this field—designed to deliver accurate, repeatable measurements in the harshest environments. Whether you are monitoring turbines, compressors, or pumps, this sensor provides the data you need to prevent unplanned downtime.

Technical Specifications

The Bently Nevada 200350-02-00-01 is a 200350 series accelerometer with a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%). It offers a frequency range of 30–600,000 cpm (0.5–10,000 Hz) and a measurement range of ±50g. Transverse sensitivity is ≤7%, and amplitude linearity is ±1%. The mounted resonant frequency is 1500 kcpm (25 kHz). Broadband electrical noise (1–10 kHz) is 350 μg (3,434 μm/s²). Output bias voltage is 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, output impedance is 10⁸ ohms. Operating temperature range is –65°F to +250°F (–54°C to +121°C). Shock survivability is 5,000 g pk. Relative humidity tolerance is 100% relative, condensing, non-submerged. Enclosure rating is IP68. Mounting thread is 1/4-28 female, with maximum 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 with welded hermetic sealing. Electrical connector is a 2-pin Mil-C-5015, top-positioned. Agency approvals include CSA, ATEX, and IECEx. Weight is 0.051 kg, height is 1.65” (4.24 cm), hex size is 11/16” (1.8 cm). Mounting stud option is 02 = ¼-28 to M8 x 1.25 stainless steel.

Industry Applications

The 200350-02-00-01 is engineered for continuous vibration monitoring in oil and gas, power generation, and heavy manufacturing. Its wide frequency range and high shock survivability make it ideal for gearboxes, centrifugal compressors, and large electric motors. The IP68 rating and stainless steel housing allow deployment in washdown areas, offshore platforms, and other corrosive or wet environments. With CSA, ATEX, and IECEx certifications, it meets safety requirements for hazardous locations.

Installation & Setup Guidance

Proper mounting is critical for accurate readings. Use the 1/4-28 female mounting thread and apply a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). Ensure the mounting surface is clean, flat, and free of debris. The sensor should be oriented with the electrical connector in the top position to prevent moisture ingress. After installation, verify output bias voltage (8–12 VDC) and allow 2.0 seconds settling time before taking measurements.

Maintenance & Reliability

Routine inspection of the electrical connector and cable for damage is recommended. The welded hermetic seal and stainless steel construction provide long-term reliability in harsh conditions. Periodic verification of sensitivity and bias voltage helps ensure consistent performance. For safety-rated installations, follow the manufacturer’s safety manual for inspection intervals.

Selection Guide & Purchasing Advice

When ordering the 200350-02-00-01, confirm the mounting stud option (02 = ¼-28 to M8 x 1.25 stainless steel), tolerance (00 = 100 mV/g ±20%), and agency approvals option (01 = CSA, ATEX, IECEx). Verify compatibility with your data acquisition system’s excitation voltage (18–28 VDC) and constant current (2–20 mA).
