FAQ

1. How does the Velomitor CT sensor detect rotational speed?
The sensor generates AC pulses in response to magnetic variations from the rotating target, allowing speed calculation based on pulse frequency.

2. What is the recommended mounting distance for optimal signal?
The sensor performs best with a gap of 0.5 mm to 5 mm from the rotating target.

3. Can it operate in high-vibration environments?
Yes, the stainless steel and epoxy construction provide excellent resistance to vibration and mechanical shocks.

4. What type of signal output does the sensor provide?
It produces an AC pulse signal proportional to rotational speed.

5. Is it compatible with other Bently Nevada monitoring modules?
Yes, it is fully compatible with standard Bently Nevada 3500 and 3300 monitoring systems.

6. What is the maximum rotational speed measurable?
The sensor can reliably measure speeds up to 60,000 RPM.

7. How resistant is the sensor to environmental factors like moisture or dust?
It has IP67/NEMA 4X protection, ensuring full resistance to dust and water ingress.

8. Can it be used in high-temperature applications?
Yes, it operates reliably in temperatures from -40°C to +120°C.

9. How does cable shielding affect performance?
Using a shielded twisted pair cable minimizes electromagnetic interference, ensuring signal integrity.

10. Does the sensor require calibration before installation?
No field calibration is needed; it provides accurate output as long as proper gap and mounting orientation are maintained.
