Industry Applications
Its 80 mils (2.0 mm) calibrated range and 200 mV/mil scale factor provide high-resolution data for trend analysis. The stainless steel armor protects against physical damage in high-vibration areas. Maintenance engineers rely on this probe for early detection of bearing wear, imbalance, and misalignment, reducing costly repairs.
Installation & Setup Guidance
Mount the 21505-68-96-05-02 using the 3/8-24 threaded configuration. Ensure the probe face is clean and the gap is set within the calibrated range (starting at approximately 10 mils from the probe face). Use the miniature male coaxial connector for secure signal transmission. Verify the power supply meets -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Calibrate the system as a whole to achieve ±4% scale factor accuracy.
Maintenance & Reliability
Inspect the probe and cable periodically for physical damage or corrosion. The probe is resistant to common industrial fluids as listed in the specifications. Keep the connector clean and dry to maintain signal integrity. The system weight of 1.3 lbs (0.59 kg) ensures easy handling during installation. No internal adjustments are needed; rely on system calibration.
Reliable Vibration Monitoring for Critical Machinery
This 8mm probe, part of the 7200 Proximity Transducer System, delivers precise displacement measurements essential for early fault detection and preventing unplanned downtime. Its robust stainless steel armor and corrosion-resistant design make it suitable for harsh industrial environments.
