Bently Nevada 330103-01-09-50-02-00 3300 XL 8 mm Proximity Probe

Description

330103-01-09-50-02-00 specifies a 3300 XL 8 mm metric thread proximity probe with a 10 mm unthreaded case section and a 90 mm overall case length. This configuration features a 5.0-meter total cable length with a miniature coaxial ClickLoc connector and standard cable material, supplied without a connector protector or hazardous area agency approvals.

This non-armored eddy-current probe is part of the Bently Nevada 3300 XL 8 mm Proximity Transducer System. It operates by measuring static and dynamic distances between the probe tip and a conductive target, such as a machine shaft, making it suitable for metric installations requiring M10 x 1 thread mounting. Sibling configurations may offer integrated stainless steel armor, connector protectors, shorter or longer lead cables, or CSA/ATEX/IECEx certifications, whereas this specific model provides a clean, standard 5.0-meter non-armored layout for safe-area zones where approvals are not required.

Features

• 10 mm unthreaded case length utilizing metric M10 x 1 threads for custom installation depths.
• 90 mm overall case length providing stable thread engagement in standard machinery housings.
• 5.0 meters total integral cable length calibrated for direct matching with 5-meter Proximitor sensors.
• Miniature coaxial ClickLoc connector provides a reliable and low-profile electrical connection.
• Non-armored design ensures standard routing flexibility inside protected conduits or machinery casings.
• No agency approvals or connector protectors selected, reducing unnecessary cost in general-purpose industrial environments.

Applications

• Radial shaft vibration measurements on industrial pumps, motors, and fans.
• Axial thrust position monitoring for rotating machinery rotors.
• Keyphasor reference and speed measurements on high-speed industrial shafts.
• General machinery protection systems requiring a robust non-contact proximity sensor.
• Industrial installations with standard metric mounting bores requiring M10 x 1 thread profiles.

Installation Guidelines

• Ensure that the thread engagement inside the bracket or machine housing does not exceed 15 mm for M10 x 1 threads to avoid binding during installation.
• Lock the probe body in place securely using an M10 x 1 lock nut with standard safety wire holes. Do not exceed the maximum recommended torque of 12.0 N-m (106 in-lb).
• Position the probe tip to set the target gap, typically 1.27 mm (50 mils) corresponding to a -10 Vdc nominal Proximitor output.
• Ensure the minimum bend radius of the non-armored coaxial cable is kept at or above 25.4 mm (1.0 in) to prevent internal core damage.
• Clean the miniature ClickLoc connector contacts prior to mating. Align the click-lock mechanisms and torque to a finger-tight connection.

Compliance and Certifications

• FCC Part 15 compliant
• RoHS Directive 2011/65/EU compliant
• EMC Directive 2014/30/EU (Standards: EN 61000-6-2, EN 61000-6-4)
• Functional Safety: SIL 2 capable (HFT=0) and SIL 3 capable (HFT=1) when used inside an appropriately designed safety instrumented system.
