Description

330906-02-12-05-02-00 specifies a Bently Nevada 3300 NSv reverse mount proximity probe configured with an unthreaded case length of 0.2 inches, an overall case length of 1.2 inches, and a 3/8-24 UNF-2A thread profile. This probe option features a 0.5-meter (20-inch) standard FEP cable with a miniature coaxial ClickLoc connector and is supplied without hazardous area agency approvals. Unlike standard-mount models that are screwed into place from outside the machine housing, reverse-mount probes are installed from the inside or rear, protecting the sensor body and maintaining position settings in tight spaces.

This probe operates with a 3300 XL NSv proximity transducer system and is interchangeable with legacy 3300 RAM proximity probe installations. The transducer system provides non-contact shaft vibration and axial position measurements on small-bore machinery or high-speed machinery where clearance constraints limit probe tip diameter.

Features

  • Thread Type: 3/8-24 UNF-2A threaded case for secure mechanical installation.
  • Unthreaded Length (Option 02): Fixed unthreaded length of 0.2 inches.
  • Case Length (Option 12): Overall case length of 1.2 inches.
  • Total Length (Option 05): Total probe length of 0.5 meters (20 inches).
  • Connector Design (Option 02): Gold-plated brass coaxial ClickLoc connector locks into place to prevent accidental loosening from vibration.
  • Agency Approvals (Option 00): Standard safe-area configuration with no hazardous area approvals required.
  • Cable Style: Unarmored 75-ohm coaxial cable insulated with fluoroethylene propylene (FEP).
  • Tip Design: Polyphenylene sulfide (PPS) tip utilizing patented TipLoc molding for secure bonding.

Applications

The 3300 NSv reverse mount probe is used for non-contact displacement, radial vibration, and axial position measurements in rotating machinery. It is suited for high-speed machinery with limited target geometry, such as aeroderivative gas turbines, centrifugal compressors, small pumps, and auxiliary equipment where standard probe casing clearances are insufficient.

Installation Guidelines

Proper installation of the 3300 NSv reverse mount probe provides accurate vibration and axial measurements:

  • Mounting: Reverse-mount probes are designed to be threaded into a mounting bracket or sleeve from the rear/inside. Tighten the probe case to a maximum recommended torque of 0.56 N-m (5 in-lb) or finger-tight to avoid casing damage.
  • Cable Routing: Maintain a minimum bend radius of 25.4 mm (1.0 inch) for the probe cable to prevent physical damage or impedance changes. Secure the cable with appropriate clips to avoid whip during operation.
  • Connector Care: Keep gold-plated ClickLoc connectors clean and dry. Avoid contact with skin oils. Slide the connector halves together until they click-lock into position.
  • Target Clearance: Ensure target size matches or exceeds the minimum recommended diameter of 8.9 mm (0.35 inches). Standard calibration is to AISI 4140 steel.

Compliance and Certifications

The 3300 XL NSv Proximity Transducer System components conform to the following standards when used as a system:

  • EMC: EN 61000-6-2 (Industrial Immunity), EN 61000-6-4 (Industrial Emissions)
  • RoHS: European Community Directive 2011/65/EU
  • Functional Safety: SIL 2 capability (HFT=0), SIL 3 capability (HFT=1) when configured as a redundant system

FAQ

What does the unthreaded and case length of the 330906-02-12-05-02-00 probe specify?

The unthreaded length is specified as 0.2 inches (Option 02) and the overall case length is specified as 1.2 inches (Option 12) with a 3/8-24 UNF-2A thread design.

What cable and connector type does this specific NSv reverse mount probe use?

This probe configuration features a 0.5-meter (20-inch) standard unarmored coaxial cable (Option 05) with a miniature gold-plated brass ClickLoc coaxial connector (Option 02).

What is the purpose of the 3300 NSv reverse mount design compared to standard mounting?

The reverse-mount probe is designed to be installed from the rear or inside of the machine casing, providing secure mounting and mechanical protection in tight environments or narrow spaces where external access is restricted.

What are the power requirements of a system utilizing this probe?

A typical 3300 XL NSv system requires -17.5 Vdc to -26 Vdc supply voltage at 12 mA maximum current consumption when operated without safety barriers.
