Bently Nevada 21505-00-60-10-02 7200 Series 8 mm Proximity Probe

Description

21505-00-60-10-02: 7200 Series 8 mm proximity probe configured with 0.0 in unthreaded length (Option 00), 6.0 in case length (Option 60), 1.0 m total cable length (Option 10), and a miniature male coaxial connector (Option 02). This transducer system provides accurate, non-contacting displacement measurements for critical rotating machinery monitoring, including axial thrust position, radial vibration, and rotor shaft position.

Designed for integration into 7200 series monitoring systems, this probe utilizes an 8 mm tip constructed of polyphenylene sulfide (PPS), offering resistance to harsh, wet, or chemically active environments. It pairs with 7200 series extension cables and Proximitors to create a complete measurement chain that adheres to API 670 requirements for industrial machinery protection.

Features

• Option 00 (Unthreaded Length): 0.0 in unthreaded probe body section.
• Option 60 (Case Length): 6.0 in total case length, featuring standard 3/8-24 threads.
• Option 10 (Total Cable Length): 1.0 m integral coaxial cable length.
• Option 02 (Connector): Miniature male coaxial connector for signal transmission.
• Construction: 8 mm diameter tip made of polyphenylene sulfide (PPS) for chemical and moisture resistance.
• System Compatibility: Compatible with 7200 Series Proximitor sensors and extension cables.
• Measurement Range: 80 mils (2.0 mm) linear measuring range with 200 mV/mil scale factor.

Applications

• Radial vibration measurement for bearing condition monitoring.
• Axial thrust position measurement to detect bearing wear.
• Rotor shaft average radial position and stability analysis.
• Vibration amplitude and phase angle for machinery diagnostics.
• Eccentricity measurement to monitor rotor bow.

Installation Guidelines

Ensure the probe is installed with the correct gap (typically 50 mils) from the target surface to maintain linear operation. Verify that the probe body is secured with the jam nut to prevent vibration-induced loosening. Cables should be routed away from high-voltage power lines to prevent EMI/RFI interference. Ensure all connectors are kept clean and free of moisture during installation.
