Bently Nevada 330105-02-12-10-02-CN 3300 XL 8 mm Reverse Mount Proximity Probe

Description

Option 02 (0.2 in unthreaded length) and Option 12 (1.2 in case length) specify this 3300 XL 8 mm reverse mount proximity probe configuration — 330105-02-12-10-02-CN. This 3300 XL 8 mm Reverse Mount Proximity Probe is used for non-contacting machinery displacement and vibration measurements when the physical mounting configuration requires installation from the rear or inside of a machine bracket, housing, or sleeve. This design prevents the probe from being pulled or pushed through the mounting hole during operation, providing enhanced mechanical security in heavy industrial installations.

This configuration is equipped with a 1.0 meter (3.3 feet) standard coaxial cable terminating in a miniature male coaxial ClickLoc connector (Option 02). Unlike standard variants which may feature standard North American or European approvals, this specific part number incorporates the -CN suffix, which delivers the China hazardous area approval package. This certification suite covers local Chinese regulatory frameworks, including NEPSI and CCC approvals, certifying the transducer for installation in potentially explosive industrial atmospheres within China.

Features

• Option 02 unthreaded length provides a fixed 0.2 inch (5.0 mm) body clearance.
• Option 12 case length defines a 1.2 inch (30 mm) threaded body for compact installations.
• Reverse mount housing design enables safe installation from inside protective sleeves or housing walls.
• Gold-plated ClickLoc coaxial connector offers robust connection reliability and low DC resistance.
• Standard 1.0 meter cable length provides an optimal link to the system extension cable.
• China-specific -CN certificate package ensures compliance with NEPSI and CCC hazardous area frameworks.

Applications

• Shaft vibration and axial position monitoring in high-speed rotating machinery.
• Radial vibration and thrust bearing wear measurement on steam turbines, gas turbines, and compressors.
• Machinery protection systems requiring reverse mount physical installation.
• Industrial installations in China necessitating NEPSI and CCC explosion-proof certifications.

Installation Guidelines

• Do not exceed the recommended torque limits during installation; maximum thread engagement length is 0.563 in (14.3 mm).
• Ensure the probe mounting location maintains adequate clearance from surrounding metal to prevent side-viewing interference.
• Connect only to a 3300 XL extension cable of a matching length to achieve a total calibrated 5-meter or 9-meter transducer system.
• Keep the miniature ClickLoc connector clean and dry, avoiding exposure to solvents or moisture during installation.

Compliance and Certifications

• NEPSI (National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation)
• CCC (China Compulsory Certification)
• RoHS Compliant
