Description

The Bently Nevada 330101-00-13-15-12-CN is an 8 mm proximity probe designed to perform precise, non-contact shaft position and dynamic vibration measurements in wet-casing environments. This specific configuration features a 3/8-24 UNF threaded body without armor, 0.0 inches of unthreaded length, a 1.3-inch overall case length, a 1.5-meter (4.9 feet) total cable length, and a miniature coaxial ClickLoc connector on a specialized FluidLoc cable. Unlike standard probe cables, the integrated FluidLoc cable utilizes a patented barrier design that prevents lubricating oils and other process liquids from traveling through the interior of the cable and escaping the machine housing. Additionally, the -CN suffix indicates that this probe comes equipped with the China hazardous area approval package, certifying compliance with NEPSI and CCC safety regulations for explosive atmospheres.

Operating on the eddy-current principle, this durable transducer is a fundamental component of the 3300 XL 8 mm Proximity Transducer System. The probe tip and body are built to withstand high temperatures and differential pressures, generating an analog output voltage that is directly proportional to the physical gap between the probe face and an observed conductive target, such as an AISI 4140 steel shaft. This proximity sensor is ideal for permanent mounting on rotating machinery including steam turbines, high-speed gas turbines, centrifugal compressors, and heavy-duty process pumps, where reliable machinery protection and fluid containment are crucial.

Features

• Eddy-current technology delivers high-accuracy non-contact displacement and vibration measurements.
• Specialized FluidLoc cable design acts as a seal, preventing oil and process liquids from leaking out of the machine housing via the cable interior.
• Rugged tip material and stainless steel threaded case are engineered for harsh, continuous-duty industrial applications.
• Features standard 3/8-24 UNF threads with a 1.3-inch overall case length and a fully unthreaded length of 0.0 inches.
• Gold-plated miniature coaxial ClickLoc connector provides a secure, vibration-resistant, finger-tight connection.
• Fully certified with NEPSI and CCC approvals under the China hazardous area approval package (-CN suffix).
• Interchangeable and backward compatible with standard 3300 XL Proximitor sensors (330180 series) and extension cables.

Applications

• Steam and gas turbine shaft vibration analysis and axial position monitoring.
• Compressor and process pump rotor displacement measurements.
• Bearing housing installations where oil containment and prevention of fluid bypass are mandatory.
• Machinery protection systems operating in explosive or hazardous areas in China requiring NEPSI and CCC certificates.
• High-speed industrial machinery casing expansion and Keyphasor speed reference sensing.

Installation Guidelines

• Mount the probe with the appropriate physical gap (typically 1.27 mm or 50 mils for standard calibration) relative to the target surface.
• Ensure that the thread engagement during installation does not exceed the maximum limit of 0.563 inches (14.3 mm) to prevent physical binding.
• Finger-tighten the ClickLoc gold connectors until they click; do not use specialized tools or pliers unless mating with non-XL components.
• Route the sensor cable using proper industrial shielding, grounding, and separation from noisy power lines to maintain high signal integrity.
• Utilize the integrated FluidLoc cable's barrier property to prevent the migration of pressurized or splashed oils out of the bearing enclosure.

Compliance and Certifications

• NEPSI: Certified for explosive atmosphere installations in China.
• CCC: China Compulsory Certificate for hazardous locations.
• CE: Fully compliant with European EMC and low-voltage directives.
• RoHS: Complies with hazardous substance restrictions.
