Bently Nevada 330704-000-030-50-02-00 3300 XL 11 mm Proximity Probe

Description

Option 000 (0 mm unthreaded length), Option 030 (30 mm case length), and Option 50 (5.0 m total length) define the exact configuration of the 330704-000-030-50-02-00 3300 XL 11 mm Proximity Probe. This standard-mount metric probe features an M14 x 1.5 threaded body with integral flexible AISI 302 stainless steel armor for robust mechanical protection under demanding industrial environments. Unlike standard-length 1.0-meter probes, this 5.0-meter configuration connects directly to a 5.0-meter Proximitor Sensor, eliminating the need for an intermediate extension cable. This direct connection model reduces connector-to-connector insertion losses and simplifies installations in tight enclosures.

In contrast to sibling probes with custom unthreaded lengths (such as Option 020 or 040), this fully-threaded 30 mm case allows for maximum adjustment range when positioning the probe within mounting brackets or internal machine housings. It is equipped with a standard triaxial cable and a miniature ClickLoc coaxial connector (Option 02) without a pre-installed connector protector, making it highly compatible with standard 3300 XL 11 mm monitoring chains. This specific variant is supplied without agency approvals (Option 00).

Features

• M14 x 1.5 metric threaded probe case constructed from AISI 304 stainless steel.
• Integrated flexible AISI 302 stainless steel armor provides mechanical protection for the triaxial cable.
• 0 mm unthreaded length (Option 000) for fully-threaded adjustability during installation.
• 30 mm overall case length (Option 030) provides compact mounting depth.
• 5.0 meter total length (Option 50) designed specifically for direct connection to a 5.0-meter Proximitor Sensor.
• Miniature ClickLoc coaxial connector (Option 02) with gold-plated brass contacts.
• Standard triaxial fluoroethylene propylene insulated probe cable.
• Standard configuration without hazardous area agency approvals (Option 00).

Applications

• Continuous non-contact radial shaft vibration monitoring in utility turbines and large compressors.
• Axial rotor position measurement in steam and gas turbine generator sets.
• Industrial rotating machinery protection systems requiring metric physical mounting interfaces.
• Non-contact eddy-current displacement sensing in harsh, oil-rich machinery environments.

Installation Guidelines

• Adjust the probe gap to approximately 2.5 mm (100 mils) from the target surface to locate the center of the 4.0 mm linear measurement range.
• Ensure the probe cable or flexible armor is not bent past the minimum rated bend radius of 25.4 mm (1.0 in) during routing.
• Do not exceed the maximum rated installation torque of 63.3 N-m (560 in-lb) for the M14 x 1.5 threaded case. Recommended torque is 21.1 N-m (187 in-lb).
• Verify that the maximum thread engagement does not exceed 21 mm to prevent binding or mechanical damage to the housing.
• Ensure that ClickLoc connectors are kept completely dry, clean, and free from lubrication or oil prior to locking the connection.

Compliance and Certifications
