Bently Nevada 330103-11-19-10-02-00 3300 XL 8 mm Proximity Probe

Description

Option 11 (110 mm unthreaded length) and Option 19 (190 mm overall case length) specify the physical envelope of this metric 3300 XL 8 mm proximity probe — 330103-11-19-10-02-00. This non-contact eddy-current displacement sensor is designed to measure static and dynamic distances between the probe tip and a rotating target. It utilizes an M10 x 1 metric thread on an unarmored brass and stainless steel body casing.

This specific variant features a 1.0-meter integrated standard coaxial cable terminated with a miniature coaxial ClickLoc male connector (Option 02, without a connector protector) and is configured without agency approval requirements (Option 00). Unlike armored counterparts, the unarmored cable offers greater flexibility for routing through sealed machine conduits or protective terminal enclosures. When combined with a matching 3300 XL extension cable and a 3300 XL Proximitor sensor, this probe forms a complete eddy-current measurement system that outputs a continuous voltage proportional to target distance.

Features

• Option 11 unthreaded length of 110 mm provides deep insertion capability for recessed shaft access.
• Option 19 overall case length of 190 mm with M10 x 1 metric thread.
• Option 10 total physical length of 1.0 meter (3.3 feet) for proximity installations.
• Option 02 miniature male coaxial ClickLoc connector for direct coupling to extension cables.
• Option 00 standard configuration suited for general purpose applications where hazardous area certificates are not requested.
• Polyphenylene sulfide (PPS) probe tip offers mechanical protection and chemical resistance inside machinery environments.

Applications

• Radial shaft vibration measurements on high-speed industrial compressors and steam turbines.
• Axial rotor position and thrust measurements on critical rotating machinery.
• Shaft speed and phase reference (Keyphasor) tracking.
• General displacement and thermal expansion monitoring on industrial pumps and gearboxes.

Installation Guidelines

• Thread the probe case manually into the mounting port to avoid cross-threading metric threads.
• Tighten the M10 x 1 threaded body to a maximum torque of 7.5 N-m (66 in-lb).
• Verify that the maximum thread engagement inside the machinery wall does not exceed 15 mm.
• Set the initial physical gap to 1.27 mm (50 mils) and confirm the gap voltage matches the system calibration curve (nominally -10 Vdc using a compatible Proximitor sensor).
• Observe a minimum cable bend radius of 25.4 mm (1.0 in) along the standard coaxial routing path.

Compliance and Certifications

• European Community Directive: EMC Directive 2014/30/EU and RoHS Directive 2011/65/EU.
• Functional Safety: Certified up to SIL 2 (HFT = 0) and SIL 3 (HFT = 1) when part of an approved machinery protection system configuration.
• Note: This specific Option 00 configuration is not certified for hazardous areas directly since Option 00 indicates no approvals are required.
