330104-06-14-05-02-05 Bently Nevada | Proximity Probe

Product Overview

The Bently Nevada 330104-06-14-05-02-05 is a precision-engineered 3300 XL 8mm Proximity Probe designed for high-accuracy vibration and position monitoring. This metric model features an M10 x 1 thread and integrated stainless steel armor for maximum cable protection. Specifically configured with a 60 mm unthreaded length and a 140 mm overall case, it is ideal for applications requiring deep reach into machine housings while maintaining the mechanical integrity of a 3300 XL transducer system.

Technical Specifications

Mechanical & Environmental Protection

1. Specialized Housing Design: This model is built with a 140 mm case length, of which 60 mm is unthreaded. This configuration allows for streamlined installation through thicker machine walls where only the final 80 mm requires thread engagement. With a standard weight of 323 grams per meter, the probe remains mechanically stable even under high-frequency vibration.

2. Superior Material Integrity: The probe tip utilizes PPS (Polyphenylene sulfide) to ensure resistance against chemical erosion and moisture. The case is reinforced with Viton® O-rings to maintain a high-pressure seal between the tip and the case, protecting internal electronics from process fluids.

3. Wiring and Signal Stability: For optimal performance, the 330104-06-14-05-02-05 supports field wiring lengths up to 305 meters (1,000 feet). Bently Nevada recommends using 3-conductor shielded triad cable to ensure minimal signal roll-off and maximum electromagnetic interference (EMI) protection.

Installation Guidelines

Maximum Thread Engagement: During installation, ensure that thread engagement does not exceed 15 mm to prevent stress on the probe case. Use the 60 mm unthreaded portion to bypass non-threaded ports or spacers.

Electrical Calibration: This probe has a nominal DC resistance of 7.45 Ω. It is calibrated to provide a standard 7.87 V/mm (200 mV/mil) scale factor when used with a matching 3300 XL Proximitor Sensor.

Intrinsically Safe Operation: As an ATEX and IECEx certified component, this probe can be used in Zone 0, 1, and 2 hazardous areas when installed with the appropriate Bently Nevada zener barriers or galvanic isolators.

Technical FAQs

Q1: What is the benefit of the stainless steel armor?
A1: The armor protects the delicate coaxial cable from abrasion, sharp bends, and crushing, which is essential when routing cables through cluttered industrial environments.

Q2: Why is the total length only 0.5 meters?
A2: Short-cable probes are often used in setups where the Proximitor Sensor is mounted very close to the machine, or where an extension cable is used to reach a junction box without excess cable slack.

Q3: Is this probe compatible with non-XL 3300 series monitors?
A3: While 3300 XL components are backward compatible with some older 3300 systems, it is highly recommended to use the complete XL system to achieve the full performance and temperature specifications.
