Bently Nevada 330704-000-060-90-02-00 3300 XL 11 mm Proximity Probe

Description

Option 000 (0 mm unthreaded length), Option 060 (60 mm overall case length), and Option 90 (9.0 meters total length) specify this metric-thread, armored configuration of the Bently Nevada 330704-000-060-90-02-00, a non-contact eddy-current 3300 XL 11 mm Proximity Probe. This industrial transducer component works as part of a 3300 XL 11 mm proximity system, generating a linear output voltage proportional to the distance between the probe tip and a target surface, such as a rotating shaft. The M14 x 1.5 metric thread and standard flexible armor make it suitable for installation in machinery housings where physical impacts, moisture, or fluid contaminants are present.

This specific variant features a flexible AISI 302 stainless steel armor sleeve with an outer FEP jacket, protecting the underlying 75-ohm triaxial cable from physical abrasion and wear. Unlike configurations containing integrated connector protectors (Option 01), this unit is optioned with a standard miniature coaxial ClickLoc connector (Option 02), allowing standard connections without additional boots. It is also supplied with the Option 00 agency approval, designated for general-purpose, non-hazardous monitoring applications.

Features

• M14 x 1.5 metric threaded probe case (Model 330704) with built-in flexible stainless steel armor.
• 0 mm unthreaded length (Option 000) allowing the full 60 mm case length (Option 060) to be utilized for depth positioning.
• 9.0 meters total probe length (Option 90) eliminating the need for an intermediate extension cable in standard installations.
• Miniature coaxial ClickLoc connector (Option 02) providing a low-profile, secure coaxial connection.
• Option 00 approval designation, ideal for general-purpose applications where hazardous area certifications are not required.

Applications

This proximity probe is used in industrial machinery protection systems to monitor axial position, radial vibration, and shaft displacement. It is commonly installed on critical rotating machinery, including steam turbines (for differential expansion measurements) and reciprocating compressors (for rod drop and rod position tracking) where physical mechanical protection from armor shielding is necessary.

Installation Guidelines

When installing the metric-threaded probe, do not exceed the recommended installation torque of 21.1 N-m (187 in-lb) for M14 x 1.5 cases, as exceeding 63.3 N-m (560 in-lb) can damage the probe body. Ensure there is a minimum clearance of 30.5 mm around the probe tip to prevent cross-talk or target-size interference from adjacent metallic surfaces. Connectors should be kept clean, dry, and secure. Minimum bend radius for the armored probe cable is 25.4 mm (1.0 inch). Proper grounding and shielding of the transducer system must be maintained back to the monitor to avoid electromagnetic interference.

Compliance and Certifications

This general-purpose configuration (Option 00) is designed for non-hazardous areas and carries the following standard compliance markings:

• CE Mark (EMC Directive 2014/30/EU, RoHS Directive 2011/65/EU)
• China RoHS Compliance
• FCC Part 15 compliant
