Product Introduction
The 21504-00-24-05-02 belongs to the Bently Nevada 7200 Proximity Transducer Systems family. This probe measures vibration and position on rotating machinery. It ships new and original in factory packing. The 8 mm tip works with a 3/8-24 thread and no lead armor. Furthermore, the calibrated range covers 80 mils (2.0 mm) starting about 10 mils (0.25 mm) from the probe face.
Technical Specifications
The 21504-00-24-05-02 includes several ordering options. First, the unthreaded length option is 00, equal to 00 mm. Next, the overall case length option is 24, equal to 2.4 in. The total length option is 05, equal to 0.5 metre (20 inches). Tolerance for this length is +0.13 metre, -0.05 metre (+5 inches, -2 inches). Finally, the connector option is 02, which means a miniature male coaxial connector.
Electrical and Output Parameters
The probe requires a power input of -17.5 Vdc to -26 Vdc with a maximum consumption of 12 mA. The scale factor is 200 mV/mil (7.87 V/mm), ±4% when calibrated as a system. Within ±9.5%, this figure includes interchangeability errors. Linearity stays within 0.8 mils (0.02 mm) of a 200 mV/mil straight line if calibrated as a system. Including interchangeability errors, linearity stays within 2.3 mils (0.06 mm) of that line. Frequency response ranges from 0 to 10 kHz (0 to 600,000 cpm), with -5% at 10 kHz. Temperature sensitivity typically shows a -3% change in scale factor at +150°F (+65°C) at a 50 mil gap (1.27 mm).
Environmental Limits
The Proximitor operating temperature spans -60°F to +212°F (-51°C to +100°C). Meanwhile, the probe and extension cable operate from -30°F to +350°F (-34°C to +177°C). Relative humidity reaches 95%, noncondensing. For 8 mm probes, corrosion resistance is strong. Specifically, probe operation is not affected by direct contact with air, water, lube oil, ammonium hydroxide, sulfuric acid (10%), MEK (methyl-ethyl ketone), or DMF (dimethylformamide). The system weight is 1.3 lbs (0.59 kg).
Installation Guide
First, confirm the mounting thread is 3/8-24. Next, set the probe tip about 10 mils (0.25 mm) from the target face. Then, secure the probe and route the 0.5 m cable. After that, connect the miniature male coaxial connector to the extension cable. Finally, verify the scale factor at 200 mV/mil and check the gap voltage against the Proximitor output.
