21504-000-032-05-02 Bently Nevada 7200 Proximity Probe

Product Introduction for the Bently Nevada 21504 Proximity Probe

The Bently Nevada 21504-000-032-05-02 belongs to the trusted 7200 Proximity Transducer Systems family. This New & Original unit comes in factory packing with a full 12-month warranty. Specifically, it features an 8mm diameter tip with standard case configuration and 3/8-24 threads. This 21504 proximity probe provides non-contact vibration and position monitoring for turbo-machinery, compressors, and other rotating equipment.

Technical Specifications of the 21504-000-032-05-02 Vibration Probe

The 21504-000-032-05-02 includes an unthreaded length of 0 mm and an overall case length of 3.2 inches. Its total length measures 0.5 metre (20 inches) with a tolerance of +0.13 metre to -0.05 metre. Moreover, this Bently Nevada 21504 probe comes equipped with a miniature male coaxial connector (Option 02). The tip construction features a solid 8 mm diameter with standard case configuration and 3/8-24 threads. Notably, this model has no lead armor.

For power requirements, this 7200 proximity probe operates on -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Its calibrated range spans 80 mils (2.0 mm), beginning at approximately 10 mils (0.25 mm) from the probe face. Furthermore, the scale factor is 200 mV/mil (7.87 V/mm) with ±4% accuracy when calibrated as a system. Within ±9.5% including interchangeability errors, this 21504-000-032-05-02 maintains reliable performance. Linearity stays within 0.8 mils (0.02 mm) for system calibration, or within 2.3 mils (0.06 mm) including interchangeability. The frequency response covers 0 to 10 kHz (0 to 600,000 cpm) with only -5% at the upper limit.

Environmental and Mechanical Ratings for the 21504-000-032-05-02

This Bently Nevada 7200 probe demonstrates exceptional temperature tolerance. The Proximitor operates from -60°F to +212°F (-51°C to +100°C) . Meanwhile, the probe and extension cable withstand -30°F to +350°F (-34°C to +177°C) . Additionally, the system handles relative humidity up to 95% , non-condensing.

For corrosion resistance, this 8 mm proximity probe remains unaffected by direct contact with air, water, lube oil, ammonium hydroxide, sulfuric acid (10%), MEK, or DMF. The temperature sensitivity shows a typical -3% change in scale factor at +150°F (+65°C) at 50 mils gap. The complete 21504-000-032-05-02 system weighs approximately 1.3 lbs. (0.59 kg) .

Installation Guidance for the Bently Nevada 21504 Proximity Probe

Installing the 21504-000-032-05-02 requires careful attention to the mounting surface and gap setting. First, clean the mounting hole threads thoroughly to ensure proper engagement with the 3/8-24 thread. Next, thread the probe into the mounting hole until the tip reaches the recommended initial gap of approximately 10 mils (0.25 mm). Then, connect the miniature male coaxial connector to the extension cable or Proximitor.

For optimal performance, maintain the probe face within the calibrated 80 mils (2.0 mm) range. Use a gap voltage meter to verify the probe operates in the linear region. Additionally, avoid bending the probe cable sharply to prevent internal damage. Finally, secure the probe locknut to prevent vibration-induced loosening during machine operation.
