Frequently Asked Questions (FAQ)

1. What is the default sensitivity of the 200350-12-00-CN model?

   It provides a nominal sensitivity of 100 mV/g with a tolerance of ±10%, suitable for most industrial vibration monitoring applications.

2. Can this sensor be used in hazardous areas?

   The sensor itself is not intrinsically safe by default, but with proper certified enclosures and barriers, it can be used in classified zones.

3. Is this model compatible with the Bently Nevada 3500 monitoring system?

   Yes, it is fully compatible and designed to work seamlessly with Bently Nevada’s condition monitoring and protection systems.

4. What type of mounting is recommended for best performance?

   Rigid mounting using a stud or screw-in base (¼-28 UNF tapped hole) ensures optimal vibration coupling and minimal measurement error.

5. Does the sensor require any recalibration over time?

   It does not require frequent recalibration. However, calibration verification every few years is recommended for high-precision applications.

6. How is the sensor affected by high temperatures?

   It operates reliably up to +121°C and is suitable for use near machinery with elevated surface temperatures.

7. Can the cable be extended beyond 12 feet?

   Yes, but signal integrity must be preserved using shielded extension cables or signal conditioning modules.

8. Is there any visual indicator or diagnostic output?

   No, the accelerometer provides a continuous analog voltage output and does not have built-in visual diagnostics.

9. What maintenance is required?

   The sensor is maintenance-free. Visual inspection during scheduled machinery shutdowns is generally sufficient.

10. How should the sensor be mounted to avoid signal distortion?

    Ensure clean, flat mounting surfaces, use a proper torque wrench for fastening, and avoid soft mounting materials to prevent dampening effects.
