The 21505-000-012-05-02 is a Bently Nevada 7200 series 8mm standard-mount proximity probe featuring an integrated flexible stainless steel armor sleeve. Fully compatible with 18745 Proximitor Sensors, this unit works seamlessly with 3300 and 9000 monitoring systems to deliver flexible programming and stable non-contact shaft vibration and displacement measurements.

Product Advantages

• Compact Design: Minimum unthreaded length of 0.0 mm and 12 mm minimum length for tight installations.

• Integral Lead: 0.5 meter (20 inch) cable with miniature male coaxial connector for flexible routing.

• System Compatibility: Combines with extension cables to achieve 5 or 9 meter total system length.

• Full Interchangeability: Probes, cables, and Proximitors of same length and part number are completely interchangeable.

• Armor Option: Stainless steel armor available for enhanced resistance to physical abuse.

• Universal Proximitor: Compatible with same Proximitors used for both 5 mm and 8 mm systems.

System Compatibility and Alternative Models

System Compatibility

• Connects to 7200 series extension cables to achieve a complete five-meter or nine-meter overall loop system length.
  Fully compatible with Bently Nevada 18745 Proximitor Sensors.
  Interfaces directly with legacy 3300 and 9000 machinery protection monitoring systems.

Alternative Models & Differences

• 21504-00-12-05-02: Identical mechanical specification and thread configuration but utilizes an unarmored standard leading coaxial cable.
  21501-00-12-05-02: Features a smaller 5mm probe head diameter with 1/4-28 UNF threads for tight space restrictions.
  21505-00-24-05-02: Provides an extended 2.4-inch overall case length instead of the short 1.2-inch case body.
