Description

Designed for critical machinery protection and industrial condition monitoring, the Bently Nevada 21504-016-032-10-02 non-contact transducer provides highly accurate static (position) and dynamic (vibration) measurements. This 8mm proximity probe is engineered to operate under harsh conditions within steam and gas turbines, compressors, pumps, and generators, integrating seamlessly with machine protection systems.

The 21504-016-032-10-02 configuration features a standard 3/8-24 UNF thread, a 1.6-inch unthreaded length, and a 3.2-inch overall case length. It is designed with a 1.0-meter total cable length and terminated with a miniature male coaxial connector without protective lead armor. The sensor delivers a calibrated range of 80 mils (2.0 mm), starting approximately 10 mils (0.25 mm) from the probe face, translating physical displacement to a linear voltage signal when paired with a compatible proximitor sensor.

Features

  • Reliable non-contact displacement and vibration measurement.
  • Robust 8mm probe tip configuration for long-term stability.
  • Excellent thermal stability across standard operating ranges.
  • Interchangeable and compatible with standard 3300 XL 8mm proximitor systems.
  • High-quality miniature coaxial connector ensures low signal attenuation.

Applications

  • Radial vibration and shaft position monitoring in turbomachinery.
  • Thrust position measurements in high-speed compressors.
  • Eccentricity measurements in steam turbines.
  • General machinery protection and diagnostic applications in power generation, oil and gas, and chemical processing plants.

Installation Guidelines

Proper gap calibration is essential for accurate measurement. The probe should be adjusted mechanically until the DC output voltage of the associated proximitor sensor matches the specified midpoint of the linear range (typically -10 Vdc). Ensure the probe cable is routed away from high-voltage cables to prevent electromagnetic interference. Standard thread-locking compound or locknuts should be used to secure the probe housing inside the machine bracket.
