Description

330709-000-050-10-12-05 specifies this 3300 XL 11 mm proximity probe with an M16 x 1.5 metric thread and no protective armor, featuring a 0 mm unthreaded length, 50 mm overall case length, 1.0 meter total length, a ClickLoc connector, and FluidLoc cable configuration. This configuration is used within 3300 XL 11 mm proximity transducer systems for non-contact vibration and position measurements on industrial rotating machinery.

This specific configuration includes Option 12, which equips the probe with a FluidLoc cable to block turbine oil or other process fluids from migrating through the cable interior. Option 05 provides multiple international approvals, making the probe suitable for service in classified hazardous areas. The unarmored design with an M16 x 1.5 thread allows direct integration into machine housings where external conduit routing is already provided.

Features

• M16 x 1.5 metric thread without armor (base model 330709) for direct housing installation.
• Option 000 specifies a 0 mm unthreaded length, utilizing the entire case length for threaded engagement.
• Option 050 provides a 50 mm overall case length.
• Option 10 provides a 1.0 meter (3.3 feet) total cable length, matching standard extension cable configurations.
• Option 12 delivers a miniature coaxial ClickLoc connector with a FluidLoc cable that blocks fluid migration through the wire.
• Option 05 provides multiple international certifications (CSA, ATEX, IECEx) for intrinsically safe and non-incendive locations.
• Polyphenylene sulfide (PPS) tip material and AISI 304 stainless steel case for longevity in harsh environments.

Applications

This 11 mm proximity probe measures shaft displacement on rotating machinery. Typical applications include:

• Radial vibration and position monitoring on steam turbines, gas turbines, compressors, and gearboxes.
• Axial thrust position measurements to detect axial shaft movement.
• Keyphasor and speed measurements on high-speed machinery shafts.
• Fluid-tight installations where turbine oil or contaminants could travel through standard cable jackets (prevented by the FluidLoc cable).

Installation Guidelines

To establish specified accuracy when installing this 3300 XL 11 mm probe:

• Hand-tighten the coaxial ClickLoc connectors first, then apply the recommended connector-to-connector torque of finger-tight up to 0.565 N-m (5 in-lb). Do not use pliers.
• Ensure the probe-to-extension cable connection is clean and dry. Use connector protectors if moisture or oil splashing is expected.
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) along the run to avoid impedance changes or internal damage.
• Tighten the M16 x 1.5 probe case to a maximum torque of 63.3 N-m (560 in-lb). The recommended mounting torque is 21.1 N-m (187 in-lb).
• Calibrate the probe gap to approximately 2.5 mm (100 mils) from the target surface (typically AISI 4140 steel) during installation.

Compliance and Certifications

This probe configuration meets the following requirements:

• EMC Directive 2014/30/EU, EN 61000-6-2 (Immunity), EN 61000-6-4 (Emissions).
• RoHS Directive 2011/65/EU and China RoHS (15-year EFUP designation).
• Hazardous Area Approvals (Option 05): ATEX, IECEx, and North American (CSA) intrinsically safe (Ex ia) and non-incendive/increased safety (Ex nA/ec) certifications when connected to certified barriers.
