Description

The 330104-00-05-20-02-05 configuration is specified by a fully threaded case with M10 x 1 metric threads and an overall case length of 50 mm, equipped with integral FEP/PFA-jacketed stainless steel armor. This eddy-current non-contact proximity probe features a 2.0-meter (6.6-foot) total cable length, terminated with a miniature coaxial ClickLoc connector, and holds CSA, ATEX, and IECEx approvals for hazardous areas.

In contrast to sibling variants that feature unthreaded portions (such as Option 01 or 02) or standard non-armored cables, the 330104 model is specifically armored along its cable length to withstand harsh industrial environments prone to mechanical abrasion. It operates as part of the 3300 XL 8 mm Proximity Transducer System, pairing with a matching 3300 XL extension cable and Proximitor sensor for continuous machinery shaft vibration, axial position, and speed monitoring.

Features

• Fully Threaded Metric Body: Option 00 specifies an unthreaded length of 0 mm (fully threaded case) with M10 x 1 threads.
• 50 mm Case Length: Option 05 establishes a case length of 50 mm for intermediate reach in standard metric brackets.
• Integral Stainless Steel Armor: Armored cable protection (330104 base model) guards the coaxial line against crushing, cutting, and abrasive wear.
• 2.0 Meter Cable Length: Option 20 provides a total cable length of 2.0 meters (6.6 feet) directly attached to the probe head.
• Miniature ClickLoc Coaxial Connector: Option 02 designates standard coaxial ClickLoc termination without an external connector protector.
• Hazardous Area Approval: Option 05 certifies compliance with CSA, ATEX, and IECEx safety standards for explosive environments.

Applications

• Machinery rotor shaft vibration measurements on industrial steam turbines and gas turbines
• Axial thrust position displacement tracking on large centrifugal compressors and pumps
• Radial shaft dynamic motion monitoring inside fluid-film bearings
• Speed sensing and keyphasor reference recording under high mechanical stress conditions
• Condition monitoring in oil and gas refineries, petrochemical plants, and power generation facilities

Installation Guidelines

• Thread Engagement: Maximum length of thread engagement for M10 x 1 threads is 15 mm. Tighten probe hex to recommended torque using standard 10 mm wrench.
• Cable Routing: Maintain a minimum bend radius of 25.4 mm (1.0 inch) for armored coaxial cables to prevent internal signal attenuation or mechanical damage.
• Connector Torque: Connect standard coaxial ClickLoc connectors finger-tight. Avoid using metal pliers directly on the gold-plated surfaces unless otherwise specified.
• Magnetic Cross-Talk: Ensure a minimum spacing of 40 mm between adjacent probe tips and avoid routing probe cables near high-voltage AC lines to prevent interference.
• Gapping: Set probe gap using a standard digital voltmeter or Proximitor output monitoring; standard radial vibration gap is -9.0 Vdc, corresponding to approximately 1.27 mm (50 mils) physical gap.

Compliance and Certifications

• ATEX / IECEx: Certified Ex ia IIC T5...T1 Ga for Zone 0 / Zone 1 installations when paired with intrinsically safe zener barriers or galvanic isolators.
• CSA/NRTL: Class I, Zone 0, AEx/Ex ia IIC T5...T1 Ga; Class I, Division 1, Groups A, B, C, D; Class II, Groups E, F, G; Class III.
• CE Mark: Fully compliant with European Community Directive EMC 2014/30/EU and RoHS 2011/65/EU.
• Functional Safety: SIL 2 certified with HFT = 0, and SIL 3 capable with HFT = 1 under IEC 61508.
