Industry Applications
The Bently Nevada 200350-02-00-00 is suitable for a wide range of rotating machinery monitoring applications, including:
-
Pumps and compressors – Detecting unbalance, misalignment, and bearing wear.
-
Motors and generators – Monitoring vibration levels to prevent electrical and mechanical faults.
-
Fans and blowers – Ensuring smooth operation and early warning of blade damage.
Because the sensor offers a frequency range up to 10,000 Hz, it can capture both low-speed and high-speed machine dynamics. The ±50g measurement range accommodates moderate to high vibration levels, making it versatile across different asset classes.
Installation & Setup Guidance
Proper mounting is essential for accurate vibration measurement. Follow these guidelines when installing the 200350-02-00-00:
- Prepare a flat, clean mounting surface on the machine casing.
- Use the 1/4-28 female thread for mounting. Apply a thin layer of coupling agent (e.g., silicone grease) to improve high-frequency response.
- Tighten to the recommended torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). Over-tightening can distort the sensor and affect readings.
- Connect the 2-pin Mil-C-5015 connector securely. Ensure the cable is routed away from moving parts and potential pinch points.
- Provide constant current excitation between 2 and 20 mA, with an excitation voltage of 18 to 28 VDC.
After installation, verify the output bias voltage (8 to 12 VDC) to confirm the sensor is powered correctly.
Maintenance & Reliability
The welded hermetic sealing and IP68 rating make the 200350-02-00-00 resistant to moisture and dust, reducing maintenance frequency. However, periodic checks are recommended:
- Inspect the cable and connector for damage or corrosion.
- Verify that the mounting torque remains within specification, as vibration can loosen fittings.
- Check output bias voltage regularly; a drift outside the 8–12 VDC range indicates a problem.
With proper care, this accelerometer provides years of reliable service, minimizing unplanned downtime and maintenance costs.
Selection Guide & Purchasing Advice
When selecting a replacement or new accelerometer, verify that the mounting thread and connector type match your existing setup. The 200350-02-00-00 uses a 1/4-28 female thread and a 2-pin Mil-C-5015 connector, which are common in industrial installations.
