330910-00-03-10-02-00 | Bently Nevada | 3300 NSv Proximity Probe

Configured for high-frequency vibration and position sensing, the Bently Nevada 330910-00-03-10-02-00 (3300 NSv Proximity Probe) provides direct physical signal acquisition of shaft radial position and dynamic motion on small-diameter machinery.

Suffix Breakdown & Model Matrix

Hardware Specifications

Mechanical Monitoring and TSI Integration

The 3300 NSv system is specifically designed for transducers where standard 8 mm probes are physically constrained by small shaft diameters or limited mounting clearance. Accurate performance is dependent on precise eddy-current probe scaling to ensure linear response within the measurement range. During installation, verify gap voltage targets typically set at -10 VDC to ensure the probe operates within the linear region. Cross-talk suppression is maintained by utilizing high-frequency carrier signals, allowing for reliable monitoring of rotor dynamics in high-speed, small-shaft applications without interference from adjacent probes.

Frequently Asked Questions

Q: Can the 3300 NSv probe be utilized with standard 3300 XL Proximitor sensors?

A: No. The 3300 NSv system requires a dedicated 3300 NSv Proximitor sensor specifically tuned for the unique electrical characteristics and resonance frequency of the 5 mm NSv probe tip.

Q: What is the recommended torque specification for the M10 x 1 probe mounting?

A: Ensure the probe is mounted securely using the provided jam nuts. Do not exceed the mechanical torque limits of the M10 threads to prevent casing deformation, which could alter the electromagnetic field linearity.

Field Installation Guidelines

1. Probe Gap Setting: Establish the initial probe-to-target gap using a calibrated feeler gauge or the voltage output method. Adjust until the static gap voltage reflects the mid-range of the sensor's linear operating curve.
2. Connector Integrity: The ClickLoc miniature coaxial connectors are sensitive to contamination. Keep protective caps installed until the moment of final connection to prevent oil or particulate ingress.
3. Shielding: Ensure the cable armor is properly secured and does not create tension on the probe body. Maintain consistent routing paths to minimize noise pickup.
4. Thermal Cycling: Given the operational temperature range up to 177 deg C, ensure that the cable transition area allows for thermal expansion without mechanical stress on the probe assembly.
