Bently Nevada 330101-00-09-10-02-CN 3300 XL 8 mm Proximity Probe

Description

Non-contacting shaft displacement and vibration measurements in critical machinery are enabled by the 330101-00-09-10-02-CN, an engineered 8 mm proximity probe belonging to the industry-standard 3300 XL series. This highly reliable sensor translates physical micro-displacement into a proportional electrical signal when connected to a compatible proximitor sensor, facilitating continuous asset health monitoring and protection against mechanical faults.

Built without protective armor, this model features a 3/8-24 UNF thread optimized for direct casing integration and precise gapping. The probe tip is constructed from high-performance polyphenylene sulfide (PPS), while the threaded casing utilizes AISI 303 or 304 stainless steel. These rugged materials ensure structural integrity and chemical resistance across extreme thermal and industrial process conditions.

Features

• Unthreaded length optimized at 0 inches for low-profile mounting profiles.
• Overall case length of 0.9 inches provides a compact physical footprint.
• Total physical cable length of 1.0 meter (3.3 feet) for direct connection to intermediate extension cables.
• Terminated with a miniature coaxial ClickLoc connector for reliable, secure, and vibration-resistant signal paths.
• Premium material construction featuring a PPS probe tip and stainless steel casing.
• Unarmored standard cable jacket designed for flexible routing inside protected enclosures or conduits.

Applications

• Continuous radial vibration monitoring on fluid-film bearing machines.
• Axial thrust position measurement on steam and gas turbines.
• Casing expansion and shaft eccentricity tracking in power generation plants.
• Critical rotating machinery protection in oil and gas refineries, petrochemical processing, and heavy industrial applications.

Installation Guidelines

• Torque Limits: Do not exceed the maximum recommended mounting torque for 3/8-24 UNF threads to avoid damaging the sensor housing or stripping the threads.
• Gap Calibration: Utilize a calibrated voltmeter connected to the proximitor sensor output to establish the appropriate physical gap (typically -10.0 Vdc bias corresponding to mid-range dynamic span).
• Cable Protection: Because this model is unarmored, ensure the coaxial cable is routed through protective conduit or secure cable trays to protect against mechanical pinching or chemical degradation.
• Bend Radius: Observe the minimum bending radius of the standard coaxial cable during installation to avoid permanent attenuation or signal noise.
