Product Overview

The Bently Nevada 330901-10-24-10-02-00 is a high-precision 3300 NSv (Near Surface) proximity probe engineered specifically for applications where standard probes fail due to restricted space or small target diameters. This transducer excels in monitoring vibration and axial position on centrifugal compressors, high-speed pumps, and small turbines where the target area is as narrow as 5 mm. By utilizing a specialized tip and coil design, the NSv system provides a stable linear output even when operating in proximity to nearby metallic surfaces that would otherwise cause signal interference. This probe serves as a critical sensory input for the Bently Nevada 3500 Monitoring System, ensuring continuous asset protection and high-fidelity data acquisition for Turbine Supervisory Instrumentation (TSI) in the most confined mechanical environments.

Component Suffix Interpretation

Understanding the NSv Model Code

The part number 330109-10-24-10-02-00 defines a specific mechanical footprint and electrical interface tailored for compact industrial housings.

• -10 (Unthreaded Length): Indicates a 1.0-inch unthreaded body length, allowing the probe to pass through thick mounting brackets before thread engagement.

• -24 (Overall Case Length): Specifies a 2.4-inch total threaded case length, providing sufficient reach for internal bearing housing access.

• -10 (Total Length): Represents a 1.0-meter (3.3 feet) total cable length, designed to be connected to a matching NSv extension cable for a 5-meter or 7-meter system.

• -02 (Connector Option): Features a miniature coaxial connector with a specialized brass cable protector for enhanced physical shielding and fluid resistance.

• -00 (Agency Approval): Designates the standard non-certified option, optimized for industrial zones not requiring specific hazardous area ratings.

Field Implementation Guidelines

Precision Gap Voltage Alignment

To ensure accurate vibration readings, engineers must calibrate the DC Gap Voltage during installation. For the 3300 NSv system, a typical gap setting of -10.00 VDC places the probe in the center of its linear operating range. Use a digital multimeter at the Proximitor output to verify this voltage before finalizing the probe locknut torque.

Cable Protection and Routing

The miniature coaxial cable requires careful handling to maintain signal integrity. Avoid sharp bends exceeding a 25.4 mm (1.0 inch) radius. Always utilize the integrated connector protectors and seal the junction with self-fusing silicone tape to prevent oil or moisture ingress from grounding the signal, which is a primary cause of "Not OK" status in the 3500 rack.

Strategic Engineering Advantages

Small Target Performance

The 3300 NSv probe utilizes a unique electromagnetic field pattern that concentrates sensing energy at the tip. This allows it to monitor shafts or targets that are significantly smaller than the standard 8mm probe limits without suffering from "side-viewing" interference from nearby machine components.

Seamless Integration and Reliability

Designed for the most demanding duty cycles, this probe integrates natively with Honeywell Experion PKS and existing Bently Nevada 3500 architectures. Its FEP cable jacket and PPS tip material offer superior resistance to synthetic lubricants and chemical exposure, ensuring long-term stability in high-temperature bearing environments where asset uptime is the highest priority.

Expert Technical Inquiry

Q1: Can I use the 3300 NSv probe with a standard 3300 XL 8mm Proximitor?

A1: No. The 3300 NSv system has a unique calibration profile. It must be paired specifically with a 3300 NSv Proximitor sensor and the correct NSv extension cable to achieve the required 200 mV/mil output.

Q2: What happens if the target diameter is smaller than the recommended 5mm?

A2: If the target is too small, the probe will experience a loss of linearity and sensitivity. This results in inaccurate vibration data. For extremely small targets, contact our technical team for specialized mounting advice.

Q3: Does this probe include mounting hardware?

A3: Standard probes include a locknut. However, for specialized housing access, we recommend verified Bently Nevada brackets to ensure the unthreaded length matches your machine casing requirements.

Q4: Is the -02 connector option compatible with standard extension cables?

A4: Yes, the -02 indicates the presence of a connector protector, but the electrical coaxial interface remains compatible with all standard 3300 NSv extension cables.
