Bently Nevada 330709-000-070-10-02-00 3300 XL 11 mm Proximity Probe

Description

An unarmored M16 x 1.5 metric threaded steel probe body with 0 mm unthreaded length (Option 000) and 70 mm overall case length (Option 070) specifies this 330709-000-070-10-02-00 3300 XL 11 mm Proximity Probe. This non-contacting eddy-current displacement sensor is designed for high-accuracy proximity measurements over an extended linear range, delivering a nominal 3.94 V/mm (100 mV/mil) output when paired with a matching Proximitor sensor and extension cable.

This configuration features a 1.0 meter total length (Option 10) and is equipped with a standard triaxial cable terminating in a miniature coaxial ClickLoc connector (Option 02) without a connector protector. Unlike sibling variants such as the 330710 series, this probe is unarmored, offering direct routing flexibility where mechanical armor conduit is not required. It is supplied under Option 00 (approvals not required), bypassing hazardous area certifications to optimize cost in general-purpose or non-hazardous monitoring zones.

Features

• Unarmored Metric Body: Designed with an M16 x 1.5 metric thread without armor, allowing direct installation in standard metric threaded ports.
• 0 mm Unthreaded Length (Option 000): Fully threaded case design to maximize mounting adaptability.
• 70 mm Overall Case Length (Option 070): Provides deep reach capabilities with up to 24 mm of thread engagement.
• 1.0 Meter Total Length (Option 10): Integrated 1.0 meter FEP-insulated coaxial cable for direct coupling with extension cables.
• ClickLoc Connector (Option 02): Gold-plated brass miniature coaxial ClickLoc connector provides a reliable, low-resistance connection.
• Extended Linear Range: Features an 11 mm tip diameter enabling a wide 4.0 mm (160 mils) linear range.

Applications

• Axial (thrust) position measurements on steam turbines and utility machinery.
• Ramp differential expansion measurements on industrial power generation turbines.
• Rod position or rod drop monitoring on large reciprocating compressors.
• Tachometer, zero speed, and phase reference (Keyphasor) signal generation.

Technical Specifications

Connections and Interfaces

This probe directly connects to a 3300 XL 11 mm extension cable (such as part number 330730) via the integrated gold-plated brass miniature male coaxial ClickLoc connector. Ensure the connection is kept clean, dry, and securely fastened during installation.

Installation Guidelines

• Set the probe gap to the recommended nominal setting of 2.5 mm (100 mils) for optimal 4.0 mm linear range operation.
• Ensure the external M16 x 1.5 thread does not exceed the maximum allowable thread engagement length of 24 mm to prevent physical binding.
• Tighten the probe case to a recommended torque of 21.1 N-m (187 in-lb). Do not exceed the maximum rated limit of 63.3 N-m (560 in-lb).
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) along the entire routing path to prevent signal degradation or physical cable wear.
• Keep coaxial connections dry and free from contaminants. Avoid exposing the probe to temperatures below -34 degC (-30 degF) to protect the internal Viton pressure seal.
