Product Overview

The Bently Nevada 330851-02-000-030-10-00-CN is a high-performance 25mm proximity probe from the 3300 XL series, specifically engineered for the most demanding steam turbine environments. Made in the U.S.A., this non-contacting sensor provides critical displacement and vibration data for large-scale rotating machinery. It is designed as a direct physical replacement for legacy 7200-series systems, offering a compact 30mm case length while maintaining exceptional thermal stability and resistance to industrial contaminants.

Technical Configuration

This 330851 model features a short-case configuration optimized for space-constrained installations:

  • Full Model: 330851-02-000-030-10-00-CN
  • Probe Case Type (02): M30x2 metric thread for high-torque secure mounting.
  • Unthreaded Length (000): 0 in; the entire 30mm case is threaded for maximum adjustment range.
  • Overall Case Length (030): 30mm AISI 304 stainless steel body.
  • Total Length (10): 1.0 meter (3.3 feet) integrated triaxial cable.
  • Armor Option (00): No Armor; standard PFA-insulated FluidLoc cable for superior flexibility.
  • Agency Approval (CN): Country-specific certification for localized industrial compliance.

Installation & Maintenance

Proper mounting is critical for the long-term reliability of the 330851-02-000-030-10-00-CN. For the M30x2 threaded case, we recommend an installation torque of 68 N•m (50 ft•lb), though it can withstand a maximum rated torque of 163 N•m. The FluidLoc cable technology prevents process fluids from wicking through the cable into the Proximitor sensor. Ensure the probe is gapped correctly during installation to stay within the linear range for 25mm systems.

Engineering Advantages

The primary advantage of the 330851 series is its extreme environment resilience. The PEEK tip and 304 SST case allow the probe to maintain accuracy in steam environments up to 200°C. With a 30mm overall case length, this version is perfect for tight bearing housings. Its broad compatibility ensures a seamless mechanical upgrade from legacy systems. Additionally, it complies with major maritime (ABS) and EMC standards, providing interference-free data near high-voltage equipment.

Technical FAQs

Q1: What is the benefit of the "No Armor" (00) option for this 30mm case?
A1: The no-armor version provides maximum cable flexibility and a lighter weight (230g), making it significantly easier to route through tight conduits where physical crushing is not a primary concern.

Q2: Can this probe withstand temporary overheating?
A2: Yes. The 330851 is rated to survive short-term temperature bursts up to 250°C (482°F) for periods of less than 24 hours without sustaining permanent calibration drift.

Q3: Is this probe intrinsically safe for hazardous areas?
A3: Yes, when installed with approved zener barriers or galvanic isolators per Bently Nevada drawing 141092, it meets Class I, Zone 0 (AEx/Ex ia IIC) safety requirements.
