Eddy-Current Scaling and Rotor Dynamic Measurement

The 3300 XL 25 mm probe uses eddy-current sensing to generate proportional displacement signals between the probe tip and conductive target surface. Therefore, the connected Proximitor Sensor converts gap changes into voltage outputs for machinery monitoring applications.

The system supports rotor dynamics analysis by providing shaft position and movement data. Additionally, gap voltage validation uses the standard -10 VDC target condition to verify correct probe installation and measurement range before machinery operation.

The large 25 mm sensing tip provides a 12.7 mm linear measurement range, which allows monitoring of large rotor axial movement and differential expansion conditions.

Frequently Asked Questions

Q: What measurement function does the 330851-02-000-060-50-00-CN provide?
A: The probe measures non-contact shaft displacement, axial position, and differential expansion through eddy-current sensing technology.

Q: Can this probe operate without a separate signal conditioner?
A: No. The probe requires a compatible Bently Nevada 3300 XL Proximitor Sensor to provide excitation and convert probe signals into monitoring outputs.

Q: What installation verification method applies to this probe system?
A: Technicians verify probe gap voltage and confirm the approximate -10 VDC operating target condition during setup.

Field Installation Guidelines

Install the probe with the specified M30 x 2 mounting thread and maintain correct probe-to-target alignment. The sensing surface must face the conductive target area without mechanical interference.

Route the coaxial cable away from high-current power conductors to reduce electrical interference. Maintain proper cable shielding and connect the shield according to the monitoring system grounding practice.

Before operation, verify probe gap voltage, mechanical clearance, and cable connection condition. Confirm that the connected 3300 XL Proximitor Sensor receives the correct probe signal before commissioning the machinery monitoring channel.
