Product Overview

When unplanned machine downtime strikes, the Bently Nevada 200350-00-00-01 200350 Accelerometer delivers the reliable vibration data you need to avoid costly failures. This industrial accelerometer, manufactured by Bently Nevada and made in the U.S.A., provides precise measurements to extend equipment life and reduce maintenance expenses. With a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, it captures both subtle and severe vibrations across a frequency range of 30-600,000 cpm (0.5-10,000 Hz). The 200350-00-00-01 is engineered for harsh environments, featuring a stainless steel housing, welded hermetic sealing, and an IP68 enclosure rating. Agency approvals include CSA, ATEX, and IECEx, ensuring compliance in hazardous areas. By investing in this accelerometer, you gain a cost-effective tool for predictive maintenance, minimizing unplanned repairs and maximizing asset uptime.

Technical Specifications Breakdown

Understanding key specs helps you evaluate the ROI of the 200350-00-00-01. Its sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%) provides a strong signal for early fault detection, reducing the risk of catastrophic failure. The frequency range of 30-600,000 cpm (0.5-10,000 Hz) covers common machine vibrations, from slow-speed bearings to high-speed turbines, allowing you to monitor a wide range of assets with one sensor. Output bias voltage of 8 to 12 VDC and excitation voltage of 18 to 28 VDC ensure stable operation with most data acquisition systems, lowering integration costs. The discharge time constant of ≥0.3 sec prevents signal distortion during transient events, improving data accuracy and reducing false alarms. These parameters directly contribute to lower maintenance costs by enabling condition-based rather than time-based repairs.

Industry Applications

The 200350-00-00-01 excels in rotating machinery monitoring across industries. In oil and gas, it tracks pump and compressor vibrations in hazardous zones, leveraging its CSA, ATEX, and IECEx approvals to avoid costly safety incidents. In power generation, it monitors turbine bearings and generator vibrations, where its ±50g range and 5,000 g shock survivability withstand startup transients and fault conditions. In manufacturing, it detects imbalance in fans and motors, reducing energy waste and extending component life. In each case, the accelerometer’s IP68 rating and 100% relative humidity tolerance allow installation in washdown or condensing environments, eliminating the need for expensive protective enclosures and reducing total cost of ownership.

Installation & Setup Guidance

Proper installation maximizes the 200350-00-00-01’s performance and lifespan. Mount using the 1/4-28 female thread and tighten to 2 to 5 ft-lb (2.7 to 6.8 N-m) to ensure reliable coupling without over-torquing. The mounting stud option 00 (¼-28 SS w/ brass tip, 0.5”) provides a secure, corrosion-resistant connection. Connect via the 2-pin Mil-C-5015 top-mounted electrical connector, which simplifies wiring in tight spaces. Apply constant current excitation of 2 to 20 mA from your monitoring system. Allow 2.0 seconds settling time (within 1% of bias) after power-up before taking critical measurements. This straightforward setup reduces installation labor costs and gets your monitoring system online faster.

Maintenance & Reliability

The 200350-00-00-01’s robust design minimizes maintenance needs. Its ceramic shear sensing element and welded hermetic sealing resist moisture and contamination, ensuring stable performance over years of service. The stainless steel housing withstands corrosive environments, reducing replacement frequency. With an operating temperature range of -65°F to +250 ºF (-54°C to +121 ºC), it functions reliably in extreme conditions, avoiding thermal-related failures. Routine inspection of the electrical connector and mounting torque ensures consistent data quality. By choosing this accelerometer, you lower long-term ownership costs through reduced spare parts and labor for replacements.

Selection Guide & Purchasing Advice

Before ordering the 200350-00-00-01, verify your system’s excitation voltage (18 to 28 VDC) and constant current (2 to 20 mA) compatibility. Confirm the mounting thread (1/4-28 female) matches your machine’s stud. For hazardous area installations, the agency approvals option 01 (CSA, ATEX, IECEx) is included.
