Industry Applications
The Bently Nevada 200350-12-00-00 excels in rotating machinery monitoring, including pumps, motors, fans, and compressors. Its wide frequency range captures both low-speed and high-speed vibration signatures, enabling early detection of bearing wear, imbalance, and misalignment.
In the oil and gas sector, this accelerometer supports condition monitoring on critical assets. The stainless steel housing and IP68 rating make it suitable for offshore platforms and chemical plants where moisture and corrosive agents are present.
For manufacturing operations, the 200350-12-00-00 integrates into automated vibration monitoring systems. Its ±50g range handles moderate to high vibration levels, while the low electrical noise (350 μg) ensures accurate data in noisy industrial environments.
Installation & Setup
Proper mounting is essential for reliable vibration data. The accelerometer features a 1/4-28 female thread for stud mounting. Apply a thin layer of coupling agent to the mounting surface to improve frequency response. Tighten the mounting stud to a torque between 2 and 5 ft-lb (2.7 to 6.8 N-m) to ensure secure attachment without damaging the sensor.
Use the M8x1.25 adhesive stud mount option (as indicated by the '12' in the part number) for non-invasive installation on curved or uneven surfaces. Ensure the surface is clean and free of debris before bonding. The sensor's top-mounted 2-Pin Mil-C-5015 connector provides easy cable routing, but avoid bending the cable sharply at the connector to prevent strain.
Connect the sensor to a signal conditioner or data acquisition system that supplies 18 to 28 VDC excitation and 2 to 20 mA constant current. Verify the output bias voltage (8 to 12 VDC) after connection to confirm proper operation.
Maintenance & Reliability
The Bently Nevada 200350-12-00-00 requires minimal maintenance due to its robust design. However, periodic inspection of the mounting integrity and cable condition is recommended. Check for any signs of corrosion or damage on the stainless steel housing, especially in humid or chemical-laden environments.
Given its welded hermetic sealing and IP68 rating, the sensor withstands harsh conditions, reducing the need for frequent replacements. This durability translates to lower lifecycle costs and minimized downtime, offering a strong return on investment for predictive maintenance programs.
Calibrate the sensor annually or per facility standards to maintain measurement accuracy. The ceramic shear element provides excellent long-term stability, but environmental factors can affect performance over time.
Compatibility & Integration
The 200350-12-00-00 accelerometer outputs a standard analog voltage signal proportional to vibration. It is compatible with most industrial vibration monitoring systems, PLCs, and DCS platforms that accept 0-5 V or 0-10 V inputs. The low output impedance (<150 ohms) ensures signal integrity over long cable runs.
Its top-mounted connector simplifies integration into existing machinery wiring. For retrofits, verify that the mounting thread (1/4-28) matches the existing stud or adapter. The sensor's compact size (height 1.65 inches) allows installation in tight spaces.
Selection Guide & Purchasing Advice
When selecting the Bently Nevada 200350-12-00-00, verify your system's excitation voltage and current requirements. The sensor needs 18-28 VDC and 2-20 mA constant current. Also, confirm that the output bias voltage range aligns with your data acquisition input specifications.
Consider the mounting stud option: '12' indicates M8x1.25 adhesive stud mount. For permanent installations, you may prefer a different mounting method. Ensure the ambient temperature stays within -65°F to +250°F (-54°C to +121°C).
