Description

330703-000-178-10-02-00: 3300 XL 11 mm proximity probe configuration specified with an M14 x 1.5 metric thread, 0 mm unthreaded length (Option 000), 178 mm case length (Option 178), 1.0 m total length (Option 10), and standard cable ending in a miniature coaxial ClickLoc connector (Option 02) without agency approvals (Option 00).

Unlike armored variants (such as the 330704 series) or those equipped with integrated connector protectors (Option 01), this specific configuration features a non-armored design with standard FEP-insulated cabling. It is used in Bently Nevada 3300 XL 11 mm monitoring chains to deliver reliable non-contact eddy-current displacement measurements, providing an extended linear range compared to standard 8 mm systems.

Features

  • M14 x 1.5 metric thread configuration (without armor) suitable for direct machinery mounting.
  • 0 mm unthreaded length (Option 000) allowing maximum thread engagement.
  • 178 mm case length (Option 178) designed for deep-reach installation depths.
  • 1.0 meter total probe length (Option 10) designed to interface with corresponding extension cables and Proximitor sensors.
  • Gold-plated brass ClickLoc coaxial connector (Option 02) ensuring secure, vibration-resistant coupling.
  • Standard FEP-insulated triaxial cable offering high chemical resistance and mechanical strength.
  • Polyphenylene sulfide (PPS) probe tip with patented TipLoc molding for a robust bond with the stainless steel case.

Applications

  • Axial (thrust) position measurements on steam turbines and large rotating machinery.
  • Ramp differential expansion measurements in industrial turbomachinery.
  • Rod position or rod drop measurements on reciprocating compressors.
  • Tachometer, zero speed, and Keyphasor phase reference signal generation.
  • Radial vibration and position monitoring in fluid-film bearing environments.

Installation Guidelines

Ensure the probe cable is routed away from high-voltage sources and sharp edges that could compromise the FEP insulation. Maintain the minimum bend radius of 25.4 mm (1.0 in) for all cable bends. When mounting, do not exceed the recommended installation torque of 21.1 N-m (187 in-lb) to prevent thread binding or mechanical damage to the M14 x 1.5 casing. Verify the probe-to-extension cable connections are clean and finger-tightened, followed by the standard torque procedure if matching specific housing requirements.

Compliance and Certifications

The standard 3300 XL 11 mm system is designed to comply with European CE markings for electromagnetic compatibility (RFI/EMI immunity) when properly installed. Since this specific configuration utilizes Option 00 (Agency Approval: Not required), it does not carry specific hazardous area certificates such as ATEX, IECEx, or CSA for explosive environments. Ensure appropriate installation area classifications are reviewed prior to commissioning.

FAQ

What does the 000-178 option indicate on the 330703-000-178-10-02-00 probe?

The 000 indicates 0 mm of unthreaded length, meaning the probe casing is fully metric threaded. The 178 specifies an overall metric case length of 178 mm, suitable for deep casing or internal mounting applications.

What target material is the 3300 XL 11 mm proximity probe calibrated to?

The probe is factory-calibrated to standard AISI 4140 steel. Calibration to alternative target materials is available upon special request.

Does the 330703-000-178-10-02-00 probe feature mechanical armor?

No, this configuration is unarmored (base model 330703). It features standard, high-durability FEP-insulated coaxial cable without stainless steel protective armor.

What is the connector type for the 330703-000-178-10-02-00 probe?

This probe features a gold-plated brass miniature coaxial ClickLoc connector (Option 02) without a connector protector. It is designed to plug directly into a standard 3300 XL 11 mm extension cable.
