330103-00-16-10-02-CN 3300 XL Proximity Probe Bently Nevada

Bently Nevada 330103-00-16-10-02-CN Overview

The Bently Nevada 330103-00-16-10-02-CN is a high-precision 3300 XL 8mm proximity probe engineered for continuous, industrial-grade machinery monitoring and vibration detection. Featuring an extended 160mm stainless steel case with M10×1 metric threading, this probe delivers exceptional structural reach and chemical resistance. It provides stable eddy current measurement paths across an active linear detection span of 2mm (0.25 to 2.3 mm / 10 to 90 mils), yielding a highly accurate linear voltage output mapping from -1 to -17 Vdc. Weighing approximately 323g/m, it ensures excellent signal stability and precise machinery protection across heavy industrial applications.

Core Technical Advantages

Excellent Thermal & Chemical Endurance

The sensor assembly withstands extreme temperature ranges, supporting probe tip operation from -62°F to +425°F and cable endurance up to +500°F. The robust housing and tip protect the internal sensing coils against corrosive machine fluids, while providing up to 56 days of 93% RH humidity resistance.

Secure ClickLoc Micro-Coaxial Connection

Equipped with an integrated 1.0-meter coaxial cable terminating in a specialized miniature coaxial ClickLoc connector. This mechanism provides a robust, vibration-resistant locking joint that prevents signal attenuation or intermittent connection dropouts caused by high-frequency machinery harmonics.

Precision Vibration Calibration

Optimized for critical machine tracking loops, the system features a 7.59Ω ± 0.5 DC resistance tolerance per meter of cable. It delivers reliable signal output stability and accurate vibration detection when calibrated to an optimal center gap setting of -9 Vdc at 1.27mm (50 mils).

Technical Specifications

Installation & Engineering Guide

Mechanical Alignment and Gap Setup

Mount the 160mm probe body securely through the machine casing wall using the M10×1 thread profile, maintaining a maximum length of thread engagement of 15 mm. Adjust the physical gap distance relative to the target shaft surface until your digital voltmeter registers exactly -9 Vdc at the Proximitor sensor output terminal, validating the perfect 1.27mm centerline operating gap. Supporting its 323g/m physical body mass correctly prevents mechanical deflection under vibration stress.

Field Extension Wiring Parameters

When extending the sensor loop to your central control cabinet or monitoring rack, use a 3-conductor shielded triad wire layout (24 to 16 AWG compatible). Keep the total field extension length restricted within a maximum wiring threshold of 1,000 feet between the 3300 XL Proximitor Sensor and the monitor to manage high-frequency signal stability and transmission consistency.

Environmental Limitations & Pre-Commissioning

Exposing the probe assembly to extreme sub-zero temperatures below -30°F may cause premature failure of the physical pressure seal. For mission-critical deployments, it is highly recommended to perform a comprehensive 24-hour burn-in period while ensuring strict compliance with the ±0.1V voltage stability requirement to avoid runtime reading offsets.

Technical FAQs

Q1: What does the 323g/m physical weight specification imply for field engineering?
A1: The 323g/m rating indicates the exact hardware density profile of the combined probe body and shielded coaxial line, giving installation engineers structural data for calculating strain relief bracket loads on long cable runs.

Q2: Why is a 24-hour burn-in period recommended for this proximity probe configuration?
A2: A 24-hour operational burn-in eliminates initial component settling variances and guarantees maximum signal stability before integrating the module into high-availability or mission-critical machinery protection systems.

Q3: What are the primary structural requirements for field wiring extensions?
A3: Extensions should utilize high-quality 3-conductor shielded triad cables within a 24 to 16 AWG range, keeping the total run under 1,000 feet to safeguard the sensor's baseline ±0.1V target voltage stability.
