Bently Nevada 21504-00-96-05-02 7200 Proximity Probe

Bently Nevada 21504-00-96-05-02 7200 Proximity Probe

Product Introduction

The Bently Nevada 21504-00-96-05-02 belongs to the trusted 7200 Proximity Transducer Systems family. This 8 mm probe is specifically engineered for non-contact vibration and position measurement. It provides accurate monitoring of shaft displacement in rotating machinery. Manufactured to exacting standards, this probe ensures reliable data collection for predictive maintenance programs.

This model features an overall case length of 9.6 inches and a total cable length of 0.5 metre (20 inches) . The unthreaded length option is set to 0 mm, making it suitable for standard mounting configurations. It also comes with a miniature male coaxial connector, simplifying the connection to extension cables or Proximitor sensors.

The probe operates with a power supply range of -17.5 Vdc to -26 Vdc. Its calibrated range extends to 80 mils (2.0 mm) , beginning at approximately 10 mils from the probe face. Consequently, it captures both static and dynamic displacement measurements effectively.

Technical Specifications

The Bently Nevada 21504-00-96-05-02 delivers exceptional measurement accuracy. Its scale factor is 200 mV/mil (7.87 V/mm) with a system accuracy of ±4%. Including interchangeability errors, the accuracy remains within ±9.5%. Additionally, linearity is outstanding at within 0.8 mils when calibrated as a system, and within 2.3 mils when including interchangeability errors.

The frequency response spans from 0 to 10 kHz (0 to 600,000 cpm) , with only a -5% deviation at the upper limit. This broad range captures both low-speed and high-speed machine vibrations. The temperature sensitivity typically shows a -396 change in scale factor at +150°F and 50 mils gap, ensuring stable readings across varying thermal conditions.

The probe tip is constructed with an 8 mm diameter and features standard 3/8-24 threads. It comes without lead armor, which reduces weight and simplifies installation in accessible locations. The case configuration is standard, fitting most industrial mounting brackets.

Environmental Limits

This probe handles extreme operating conditions effectively. The Proximitor operates between -60°F and +212°F (-51°C to +100°C) . Meanwhile, the probe and extension cable tolerate temperatures from -30°F to +350°F (-34°C to +177°C) . This wide range makes it suitable for both cryogenic and high-heat applications.

Relative humidity tolerance reaches 95% non-condensing, allowing deployment in humid environments without performance degradation. For 8 mm probes like this model, corrosion resistance is particularly impressive. Direct contact with air, water, lube oil, ammonium hydroxide, 10% sulfuric acid, MEK, or DMF does not affect probe operation. Therefore, it works well in chemical processing plants and offshore platforms.

Installation Guidelines

Installing the 21504-00-96-05-02 requires following standard proximity probe practices. First, clean the mounting surface thoroughly to ensure proper seating. Next, thread the probe into the mounting bracket using the 3/8-24 threads. Apply appropriate torque to secure it firmly without damaging the housing.

Then, connect the miniature male coaxial connector to the extension cable or directly to the Proximitor. Ensure the connector is tight to maintain signal integrity. After installation, set the initial gap according to the target range. Finally, verify the output voltage to confirm the probe operates within the calibrated range.
