Description

330851-02-000-060-50-00-00: 3300 XL 25 mm proximity probe, M30x2 thread, Option 000 fully threaded metric case, Option 060 60 mm overall case length, Option 50 5.0 m total system length, Option 00 standard unarmored coaxial cable, Option 00 no agency approvals.

This specific configuration incorporates an M30x2 metric thread (Option 02) and a 60 mm overall case length that is completely threaded (0.0 mm unthreaded). Operating as an eddy-current displacement sensor, this probe integrates with a 3300 XL 25 mm Proximitor sensor and a 3300 XL extension cable to measure large-target displacement. The integrated 5.0-meter PFA-insulated triaxial FluidLoc cable (Option 50) features front and rear seals that work together with the cable jacket to prevent moisture from entering the probe tip, maintaining electrical integrity in humid and harsh conditions. The clickLoc connector on the probe lead has a removable collar to simplify routing through tight clearances.

Features

  • Metric Case Threading: M30x2 metric thread (Option 02) with 60 mm overall case length (Option 060) and 0.0 mm unthreaded length (Option 000) for fully threaded mounting configurations.
  • Integrated 5.0-Meter Cable: Option 50 specifies a 5.0-meter (16.4 feet) total system length with PFA-insulated, 75 ohm FluidLoc triaxial cable to prevent moisture and fluid migration.
  • Unarmored Design: Option 00 provides a flexible, non-armored cable configuration for direct installation where mechanical armor is not required.
  • Gold-Plated ClickLoc Connectors: Supplied with corrosion-resistant ClickLoc miniature coaxial connectors featuring a removable nut collar on the probe lead.
  • Standard Integrity: Option 00 agency approval option for non-hazardous locations or applications where specialized certifications are not needed.

Applications

  • Differential expansion (DE) monitoring on mid-to-large-size steam turbine generators.
  • Non-contacting shaft vibration and axial position measurement on large rotating machinery.
  • Thrust position measurements on rotors with large axial travel.
  • Rod-drop style applications on reciprocating compressors.

Extension Cable Interface Connects to 3300 XL 25 mm extension cable (such as model 330854)
Connector Material Gold-plated brass and gold-plated beryllium copper

Installation Guidelines

Ensure standard installation practices are followed for optimal transducer system operation:

  • Thread Torque: For standard mount M30x2 thread probes, do not exceed the maximum rated torque of 163 N-m (120 ft-lb). The recommended mounting torque is 68 N-m (50 ft-lb).
  • Locking: The probe case comes standard with a locknut featuring predrilled safety wire holes to prevent loosening under heavy vibration.
  • Moisture Mitigation: All ClickLoc connectors must remain clean and free from oil, grease, and water. Connect each junction finger-tight, and utilize the provided silicon connector protectors or self-fusing tape for additional environmental isolation.
  • Routing: The miniature coaxial connector's removable nut collar allows for easier routing through tight electrical conduits and clearances.
