Bently Nevada 330101-00-08-10-11-00 3300 XL 8 mm Proximity Probe

Description

To deliver high-precision, non-contact shaft displacement and vibration measurements, the Bently Nevada 330101-00-08-10-11-00 serves as a highly specialized 8 mm proximity probe within the 3300 XL monitoring series. This specific configuration features a fully threaded 0.8-inch case without armor, a 1.0-meter total length, and a patented FluidLoc cable with an integrated connector protector. Unlike standard cable options, the FluidLoc design prevents oil, process lubricants, and other industrial fluids from leaking out of machine housings through the interior of the cable. These combined features make this configuration ideal for wet, oil-submerged, or high-pressure machine casings where fluid containment is critical.

Operating on the eddy-current principle, this proximity probe detects static and dynamic shaft position changes relative to its 8 mm tip. The raw signal is transmitted via a high-frequency coaxial connection to a compatible 3300 XL Proximitor sensor, which translates the impedance variation into a clean proportional voltage output. This system provides exceptionally stable linear output across a 2.0 mm (80 mils) measurement range, fully complying with API 670 standards for reliability and thermal stability when integrated into a complete 3300 XL transducer chain.

Features

• Non-contact eddy-current displacement measurement with an 8 mm tip diameter
• FluidLoc cable technology seals the cable interior to prevent oil or other fluids from leaking out of the machine casing
• Integrated ClickLoc miniature coaxial connector with fluorosilicone connector protector for enhanced environmental shielding
• Fully threaded 0.8-inch stainless steel case (3/8-24 UNF thread) without armor for standard direct mounting
• Rugged polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel probe body for superior durability in harsh machine environments
• Fully compatible and interchangeable with standard Bently Nevada 3300 XL Proximitor sensors and extension cables

Applications

• Shaft vibration and dynamic position monitoring on steam and gas turbines
• Axial displacement and radial vibration monitoring on high-speed compressors, turbo-expanders, and pumps
• Critical rotating machinery protection in wet, oily, or oil-mist environments where fluid containment along the sensor cable is mandatory
• Permanent monitoring installations on fluid-film bearing housings

Installation Guidelines

• Mount the probe with the appropriate probe gap as specified by system calibration (typically 1.27 mm or 50 mils for a standard range of 2.0 mm / 80 mils).
• Route the FluidLoc probe cable using standard low-noise coaxial routing techniques. Avoid sharp bends, maintaining a minimum cable bend radius of 25.4 mm (1.0 in).
• Shielding and grounding: ensure proper shielding and grounding practices are observed to eliminate electromagnetic interference (EMI). Connect the shield to the Proximitor sensor housing or appropriate instrumentation ground.
• Tighten the probe case lock nut using safety wire holes if required to prevent rotational loosening under high machine vibration.

Compliance and Certifications
