Bently Nevada 330104-07-14-05-01-00 3300 XL 8 mm Proximity Probe with Armor

Description

Option 07 (70 mm unthreaded length) and Option 01 (coaxial ClickLoc connector with connector protector, standard cable) specify this metric 3300 XL 8 mm probe configuration — 330104-07-14-05-01-00. This non-contact eddy-current sensor measures shaft vibration, axial position, and keyphasor reference on rotating machinery.

Featuring a heavy-duty stainless steel armored sheath, this variant provides enhanced mechanical shielding for the coaxial lead. This specific combination of a 140 mm case, 70 mm unthreaded segment, and 0.5-meter cable length matches specific machine housing geometries and integrates with 3300 XL Proximitor sensors and extension cables without requiring hazardous area agency approvals.

Features

• Stainless steel armor with FEP outer jacket provides protection from physical impact and chemical exposure.
• Option 07 provides 70 mm of unthreaded length on a 140 mm overall metric case.
• Metric thread configuration with M10 x 1 casing thread matches European and ISO machinery mounting standards.
• Option 01 miniature coaxial ClickLoc connector includes a pre-installed fluorosilicone connector protector.
• Compact 0.5-meter total cable length is suitable for direct connections to nearby junction boxes.
• No agency approvals (Option 00) for general purpose, non-hazardous area applications.

Applications

• Shaft vibration and dynamic displacement measurements on steam and gas turbines.
• Axial rotor position and thrust bearing wear monitoring in high-pressure compressors.
• Speed and tachometer measurements using keyphasor reference signals on industrial pumps.
• Machinery protection systems within power generation, oil and gas, and petrochemical facilities.

Installation Guidelines

• Thread Engagement: Do not exceed 15 mm of thread engagement inside the bracket or machine housing to prevent mechanical binding of the M10 x 1 casing.
• Bend Radius: Maintain a minimum bend radius of 25 mm (1.0 inch) for the armored cable to avoid damage to the coaxial core and steel armor.
• Connector Care: Clean connection surfaces with a dry, lint-free cloth before joining ClickLoc connectors. Tighten only to finger-tight pressure.
• Gap Calibration: Establish the static operating gap within the linear range of the transducer system (typically 2.0 mm or 80 mils) using a voltmeter.
• Grounding: Connect the outer shield of the extension cable to the designated instrument ground terminal at the Proximitor sensor housing. Do not ground the probe tip or casing.
