Description

Option 02 (0.2 in unthreaded length), Option 12 (1.2 in overall case length), Option 15 (1.5 m total length), Option 12 (FluidLoc cable), and suffix -CN (China hazardous area approval package) specify this Bently Nevada 330105-02-12-15-12-CN reverse mount proximity probe configuration. This non-contacting eddy-current sensor is used for shaft vibration and axial position measurement on rotating machinery, pairing with a 3300 XL Proximitor sensor and standard extension cable. Unlike standard configurations using the standard cable (Option 02) or alternative agency approvals, this variant integrates a FluidLoc cable (Option 12) which blocks fluid migration along the coaxial core. The configuration is constructed with a 3/8-24 UNF thread body, a fixed 0.2-inch unthreaded length, and a 1.2-inch overall case. The -CN suffix adds NEPSI and CCC certified hazardous area protection, making it compliant for deployment within Chinese industrial operations.

Features

FluidLoc cable (Option 12) prevents process liquid leakage along the cable interior
Reverse-mount design featuring 3/8-24 UNF-2A threading and integrated hexagonal wrench flat
1.5-meter (4.9 feet) total system probe length (Option 15) matching 3300 XL 5-meter or 9-meter systems
0.2-inch unthreaded case length (Option 02) with 1.2-inch overall case length (Option 12)
Miniature male coaxial ClickLoc connector provides secure coupling to extension cables
-CN suffix compliance includes NEPSI and CCC certifications for hazardous locations in China

Applications

Industrial rotating machinery monitoring including steam turbines, gas turbines, and compressors
Shaft axial position and radial vibration measurements
Fluid-submerged environments requiring high-resistance cable sealing
Hazardous industrial zones within China requiring CCC and NEPSI approvals

Connections and Interfaces

The probe features an integrated miniature male coaxial ClickLoc connector designed to connect securely with a standard 3300 XL extension cable. No special tools are required, and the connector is rated for finger-tight installation.

Installation Guidelines

For 3/8-24 UNF threads, the maximum length of thread engagement is 0.563 in.
Ensure coaxial cable routing maintains a minimum bend radius of 25.4 mm (1.0 in) to prevent damage. Avoid kinking or stretching the cable.
The reverse mount probe is typically mounted from the rear side of a machine casing using an optional probe sleeve or bracket. Avoid over-tightening during installation.
Handle the FluidLoc cable carefully; although designed to prevent oil migration, excessive bending can degrade performance.

Compliance and Certifications

NEPSI (Explosion Protection Certification)
CCC (China Compulsory Certification)
CE Compliant

Product Documentation

Technical Datasheet (PDF) Complete specifications and technical drawings.

What is the purpose of the Option 12 FluidLoc cable on the 330105-02-12-15-12-CN probe?

The Option 12 FluidLoc cable is designed to block oil or other process fluids from migrating along the coaxial core inside the cable. This option is utilized in applications where the probe or cable might be submerged or exposed to higher process pressures.

What is the significance of the -CN suffix on this model?

The -CN suffix indicates that the proximity probe is certified under the China Compulsory Certification (CCC) and National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation (NEPSI) hazardous area standards for use in China.

How is the 330105-02-12-15-12-CN reverse mount probe installed?

Unlike standard probes that are threaded from the outside, the reverse mount probe is threaded from the rear of the machine casing, often utilizing a probe sleeve or bracket. It uses a 3/8-24 UNF thread with a case length of 1.2 inches.

What is the total length of this proximity probe?

This configuration (Option 15) has a total probe length of 1.5 meters (4.9 feet). It must be paired with the appropriate extension cable and 3300 XL Proximitor sensor to achieve the total system length (typically 5 or 9 meters).
