Description

Unthreaded length of 60 mm (Option 06), overall case length of 150 mm (Option 15), and a 1.0 m total length (Option 10) specify this 3300 XL 8 mm proximity probe configuration — 330103-06-15-10-12-05.

This specific configuration features a FluidLoc cable (Option 12), which prevents oil and other process liquids from leaking out of the machine through the cable's interior, unlike standard non-FluidLoc cables. This variant has an M10 x 1 metric thread case (without armor) and includes standard CSA, ATEX, and IECEx approvals (Option 05) for deployment in hazardous areas. It operates as part of the 3300 XL 8 mm Proximity Transducer System, converting eddy-current displacement measurements into a proportional electrical signal when paired with a compatible 3300 XL Proximitor sensor and extension cable.

Features

• Unthreaded Length (Option 06): 60 mm unthreaded portion for mounting flexibility and specific housing depth requirements.
• Overall Case Length (Option 15): 150 mm overall case length with M10 x 1 thread configuration.
• Total Probe Length (Option 10): 1.0 meter (3.3 feet) total probe cable length.
• FluidLoc Cable (Option 12): Patented cable design containing an internal sealant that blocks fluids, oil, and moisture migration along the core.
• Hazardous Area Approval (Option 05): Certified for intrinsically safe and non-incendive installations under CSA, ATEX, and IECEx standards.
• Interchangeable Design: Fully compatible with non-XL 3300-series 5 mm and 8 mm system components.

Applications

This proximity probe is used for non-contacting machinery protection and condition monitoring in critical industrial rotating equipment. Typical applications include:

• Radial vibration and axial position measurements on steam and gas turbines
• Shaft displacement monitoring in large pumps and compressors
• Rotational speed measurements and phase reference (Keyphasor) sensing
• Oil-lubricated bearing housing monitoring where FluidLoc cable prevents fluid bypass

Installation Guidelines

To ensure proper installation of the 3300 XL 8 mm proximity probe, observe the following guidelines:

• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) during routing to prevent core damage.
• Thread engagement into the mounting structure must not exceed 15 mm for M10 x 1 threads to avoid mechanical binding.
• The gold-plated ClickLoc connectors must be tightened finger-tight until they "click" into place; do not use pliers unless connecting to a non-XL stainless steel connector.
• Avoid routing the probe cable near high-voltage lines or sources of excessive electromagnetic interference.
• For oil-exposed applications, verify that the FluidLoc cable seal is intact to ensure zero process liquid bypass.
