Bently Nevada 21504-00-52-10-02 5 mm and 8 mm Standard Mount Probe

Description

21504-00-52-10-02 is a 7200 series 8 mm standard mount proximity probe configured with a 0.0 in unthreaded length (Option 00), 5.2 in case length (Option 52), and 1.0 m total cable length (Option 10). This non-contacting, eddy-current transducer is designed for accurate measurement of both static and dynamic distances between the probe tip and the observed target, primarily for shaft position and vibration monitoring on rotating and reciprocating machinery.

This probe configuration includes a miniature male coaxial connector (Option 02) and is constructed from high-performance polyphenylene sulfide (PPS), suitable for environments where durability and chemical resistance are required. The system provides an 80 mil (2 mm) linear measuring range and is compatible with existing 7200 series Proximitor sensors and monitoring systems.

Features

• 8 mm probe tip diameter for standard 7200 series applications
• Option 00: 0.0 in unthreaded probe body length
• Option 52: 5.2 in total case length
• Option 10: 1.0 m total integral cable length
• Option 02: Miniature male coaxial connector
• Constructed from high-performance PPS plastic

Applications

• Radial vibration measurements for bearing condition monitoring
• Axial thrust position monitoring for thrust bearing wear indication
• Shaft average radial position for rotor stability analysis
• Eccentricity measurements for rotor bow detection
• Gas and steam turbines, compressors, centrifuges, and large electric motors

Installation Guidelines

Ensure the probe is mounted in a rigid bracket to prevent vibration-induced signal errors. Maintain the correct probe gap as specified by the machinery monitoring requirements. When routing the coaxial cable, avoid sharp bends and ensure the cable is secured to prevent abrasion or stress on the connector junction. For hazardous locations, verify the installation meets the specific requirements defined in Bently Nevada Data Sheet L1035 regarding system certification.

Compliance and Certifications

Compatible with API 670 requirements. Certified by CSA, BASEEFA, and FM for use in specific hazardous locations (consult product documentation for current certificate status).
