Bently Nevada 330709-00-05-10-12-05 3300 XL 11 mm Proximity Probe

Description

Option 00 (0 mm unthreaded length) and Option 12 (coaxial ClickLoc connector, FluidLoc cable) specify this 3300 XL 11 mm proximity probe configuration — 330709-00-05-10-12-05, an eddy-current 3300 XL 11 mm Proximity Probe. This variant provides non-contact displacement measurements within a 3300 XL 11 mm monitoring chain, operating with an M16 x 1.5 metric thread and without stainless steel armor. The FluidLoc cable configuration prevents oil and fluid leakage from the machine housing through the cable interior, making it suitable for applications where containment of lubricants or process fluids is required.

The probe works with a 3300 XL 11 mm Proximitor Sensor (such as the 330780 series) and a 330730 extension cable. Together, they form a transducer system calibrated to AISI 4140 steel, generating a linear range of 4.0 mm with a scale factor of 3.94 V/mm (100 mV/mil). This configuration includes Multiple Approvals (Option 05), matching requirements for installation in hazardous environments.

Features

• FluidLoc cable construction prevents oil and moisture migration through the cable interior
• Unarmored FEP insulated triaxial cable with a maximum outside diameter of 3.9 mm
• Option 00 unthreaded length (0 mm) and Option 05 case length (50 mm) for flush mounting
• Gold-plated brass ClickLoc coaxial connector provides a secure mechanical and electrical connection
• TipLoc probe tip molding establishes a secure bond between the polyphenylene sulfide tip and the stainless steel case
• Option 05 multiple approvals package for hazardous area installations

Applications

• Steam turbine ramp differential expansion monitoring
• Reciprocating compressor rod position and rod drop measurements
• Turbine and compressor shaft radial vibration and axial (thrust) position tracking
• Industrial rotating machinery phase reference (Keyphasor) and speed measurements

Installation Guidelines

• Always maintain the minimum bend radius of 25.4 mm (1.0 in) for the FluidLoc coaxial probe cable.
• The recommended mounting torque for M16 x 1.5 probe cases is 21.1 N-m (187 in-lb), with a maximum rated limit of 63.3 N-m (560 in-lb).
• Check the probe gap setting using a digital voltmeter connected to the Proximitor Sensor's output terminals. A nominal gap of 2.5 mm (100 mils) corresponds to approximately -9 Vdc output under standard conditions.
• Do not install standard connectors inside machine casings where exposure to oil or harsh fluids is expected; use FluidLoc cabling and appropriate sealing.

Compliance and Certifications

• EMC Directive: 2014/30/EU (EN 61000-6-2, EN 61000-6-4)
• RoHS Directive: 2011/65/EU
• Hazardous Area Approvals (Option 05): Multiple global certifications including ATEX, IECEx, and CSA for intrinsically safe (ia) and non-incendive (nA/ec) installations when installed per Bently Nevada drawings 141092 or 140979.
