Bently Nevada 330703-000-040-10-02-00 3300 XL 11 mm Proximity Probe

Description

An unarmored, metric thread M14 x 1.5 probe body with 0 mm unthreaded length (Option 000) and 40 mm overall case length (Option 040) specifies the configuration of the 330703-000-040-10-02-00 3300 XL 11 mm Proximity Probe.

This configuration incorporates a 1.0-meter total length standard triaxial cable (Option 10) terminated in a miniature coaxial ClickLoc connector without a connector protector (Option 02). Unlike armored options within the 3300 XL series, this unarmored variant is designed for installation environments where existing protective conduits or machine enclosures shield the cable from mechanical damage. The probe is supplied with no agency approvals required (Option 00), making it suitable for standard industrial, non-hazardous monitoring locations.

Features

• M14 x 1.5 metric thread case (unarmored) constructed from AISI 304 stainless steel.
• Polyphenylene sulfide (PPS) probe tip material for chemical and mechanical robustness.
• 0 mm unthreaded length (Option 000) paired with a 40 mm case length (Option 040).
• 1.0-meter (3.3 feet) standard triaxial cable insulated with fluoroethylene propylene (FEP).
• Gold-plated brass miniature coaxial ClickLoc connector (Option 02) without connector protector.
• General-purpose configuration (Option 00) with no agency approvals required.
• 75 Ohm triaxial probe cable matched to 3300 XL 11 mm Proximitor sensor impedance.

Applications

This proximity probe is used within a 3300 XL 11 mm monitoring chain for non-contacting displacement measurement. Typical target installations include:

• Radial vibration and position monitoring on utility turbines and compressor shafts.
• Axial position and thrust measurement on critical rotating industrial machinery.
• Keyphasor and speed measurement on high-speed industrial shafts.
• General machinery protection monitoring in non-hazardous industrial environments.

Installation Guidelines

To establish successful physical and electrical installation of the 3300 XL 11 mm proximity probe, observe the following engineering guidelines:

• Maintain a minimum bend radius of 25.4 mm (1.0 in) on all triaxial cables to prevent impedance mismatch and core breakage.
• When tightening the M14 x 1.5 threaded probe case, do not exceed the maximum rated torque of 63.3 N-m (560 in-lb). The recommended mounting torque is 21.1 N-m (187 in-lb).
• Ensure the total physical length of the probe and extension cable matches the calibrated system length (5.0 meters or 9.0 meters) specified by the Proximitor sensor. For this 1.0-meter probe, pair with a 4.0-meter extension cable for a 5.0-meter system, or an 8.0-meter extension cable for a 9.0-meter system.
• Protect the ClickLoc coaxial connection using connector protectors or self-fusing silicone tape in environments where the cable joins will be exposed to turbine oil or liquids.
• Avoid exceeding the thread engagement limits to prevent binding during installation.

Compliance and Certifications

This specific configuration (Option 00) does not require hazardous area agency certifications. For applications requiring ATEX, IECEx, or North American hazardous area approvals, select configurations ending in Option 05.
