Penerangan

Product Overview

The Bently Nevada 330851-02-000-066-50-00-05 is a high-performance 25mm proximity probe within the 3300 XL series, designed for large-scale machinery protection. This eddy current sensor provides exceptional linear range for monitoring vibration and axial position on massive shaft surfaces. Engineered for the most extreme industrial conditions, it features a PEEK tip and triaxial cabling to ensure signal integrity near high-voltage electrical equipment and corrosive fluids.

Technical Configuration

  • Model Number: 330851-02-000-066-50-00-05
  • Probe Size: 25 mm Diameter High-Performance Tip
  • Thread Specification: M30 x 2 Metric Threads (02)
  • Unthreaded Length: 0 mm (000)
  • Case Length: 66 mm Total Length (066)
  • Total Length: 5.0 Meters / 16.4 Feet (50)
  • Connector Option: Miniature Coaxial Connector (00)
  • Agency Approval: Multiple Hazardous Area Approvals (05)

Technical Specifications

Linear Range 12.7 mm (500 mils) Sensitivity 0.787 V/mm (20 mV/mil)
Ingress Protection IP68 & IP69K Dual Rated Tip Material PEEK (Polyetheretherketone)
Compliance ATEX/IECEx Zone 0/1/2, API 670, ABS Marine Approved

Installation & Maintenance

1. Torque Requirements: To comply with API 670 standards, the 330851-02-000-066-50-00-05 must be installed with a maximum torque of 68N·m. Proper thread engagement is critical to prevent loosening during high-vibration operation.

2. Gap Calibration: This 25mm probe requires specific gapping relative to the target material. Utilize the 3300 XL 25mm Proximitor Sensor for signal conditioning to ensure the 12.7mm linear range is fully utilized.

3. Environmental Sealing: The gold-plated miniature coaxial connectors should be kept clean and dry. In high-humidity environments, use Bently Nevada connector protectors or silicone self-fusing tape to maintain the IP68 integrity.

Engineering Advantages

The Bently Nevada 3300 XL 25mm system provides the largest linear range in the proximity probe family, making it indispensable for large steam turbines and thermal expansion monitoring. The PEEK tip construction offers superior chemical resistance against synthetic lubricants and high-pressure steam. With a 2,000-hour salt spray rating (ISO 9227), this probe is ideal for offshore platforms and marine propulsion systems where salt-air corrosion is a constant threat.

Technical FAQs

Q1: Is this probe compatible with standard 8mm Proximitors?
A1: No, the 330851-02-000-066-50-00-05 requires a dedicated 3300 XL 25mm Proximitor due to its unique sensitivity and power requirements.

Q2: Can it withstand high-pressure washdowns?
A2: Yes, the IP69K rating ensures the probe can withstand high-pressure, high-temperature steam jets often used in industrial cleaning.

Q3: What target material is it calibrated for?
A3: Standard calibration is for AISI 4140 steel. For other alloys, field calibration or specific factory scaling may be required.
