Product Overview

The 330104-01-09-10-11-05 is a metric-threaded, armored proximity probe from Bently Nevada’s premier 3300 XL 8 mm transducer line. This sensor is engineered for non-contacting displacement measurement, translating the physical gap between the probe tip and a conductive target into a precise voltage signal. This specific 1.0-meter configuration is optimized for Turbine Supervisory Instrumentation (TSI), providing critical data for radial vibration, axial thrust position, and speed (Keyphasor) monitoring. Its armored construction ensures maximum signal integrity and mechanical protection in the high-stress environments typical of steam turbines, compressors, and high-speed industrial fans.

Technical Configuration

The specific alphanumeric configuration of the 330104-01-09-10-11-05 model defines the following technical profile:

• Model Series: 330104 (M10 x 1 Metric Thread with Stainless Steel Armor)

• Unthreaded Length: 10 mm (01 option)

• Overall Case Length: 90 mm (09 option)

• Total System Length: 1.0 Meter / 3.3 Feet (10 option)

• Connector Interface: Miniature coaxial ClickLoc connector with Connector Protector (11 option)

• Agency Approvals: Multiple international certifications including ATEX, IECEx, and CSA (05 option)

• Scale Factor: 7.87 V/mm (200 mV/mil)

• Linear Range: 2.0 mm (80 mils)

Advanced Durability and Construction

This probe utilizes patented manufacturing techniques to ensure longevity and accuracy under extreme operational conditions. The probe tip is made of high-performance Polyphenylene Sulfide (PPS) and is hermetically sealed to the stainless steel body via the TipLoc molding process. This ensures the sensor remains vacuum-tight and resistant to the wicking of oil or process fluids.

The CableLoc design provides an internal anchoring system that withstands up to 330 N (75 lbf) of pull strength, preventing lead damage during installation. Furthermore, the flexible 304 stainless steel armor protects the FEP-insulated coaxial cable from abrasion and physical impact within the machinery housing.

System Compatibility and Application

As a core element of a machinery protection system, the 330104-01-09-10-11-05 offers:

• Complete Interchangeability: Probes, extension cables, and Proximitor sensors of the same system length (1m) can be swapped without manual bench calibration.

• Backward Compatibility: Electrically and physically compatible with legacy non-XL 3300 series 5 mm and 8 mm components.

• Enhanced Interference Resistance: Advanced circuitry provides superior RFI/EMI immunity, meeting European CE standards without the need for specialized shielded conduits.

• Hazardous Area Readiness: Certified for use in Zone 0, 1, and 2 environments, making it suitable for global oil and gas and power generation applications.
