Product Details: Bently Nevada 21500-00-16-05-02 is a 7200 series eddy current proximity probe, matched with 21747-085-00 extension cable to form a complete non-contact eddy current transducer system for Bently Nevada TSI machinery protection system. This transducer system works together with the matching proximitor driver to convert the gap variation between probe tip and rotating metal shaft into proportional voltage signals, realizing continuous measurement of shaft radial vibration, thrust position, shaft eccentricity and differential expansion for turbines, compressors, generators and pumps in power, petrochemical and heavy industrial fields.

Installation steps for this transducer system: First, inspect the probe, extension cable and connectors to confirm no damage, scratch or cable breakage before installation. Install the proximity probe vertically on the machine casing through threaded hole, ensure the probe tip keeps perpendicular to the shaft surface, adjust the static gap between probe tip and rotating shaft according to system calibration requirement, then lock the jam nut to fix probe position. Connect the probe cable to 21747-085-00 extension cable carefully, tighten the connectors properly and install protective sleeve for connector parts. Route the extension cable with gentle bending radius, avoid sharp bending, pulling and extrusion, fix the cable with cable ties properly to reduce vibration impact. Connect the other end of extension cable to the proximitor sensor, complete wiring and power on, then verify gap voltage and signal stability.

Daily maintenance requirements: Conduct regular visual inspection to check probe surface for oil contamination, corrosion and mechanical damage, check cable sheath for aging, crack and connector looseness. Use TK-3E test kit to perform periodic static gap calibration and dynamic simulation test to verify system linearity and measurement accuracy. Keep the cable away from high-voltage power cables and strong electromagnetic interference sources. When the monitoring system reports transducer fault alarm, check connector continuity and cable integrity first. Do not disassemble the probe or cut the extension cable arbitrarily. Clean oil and dirt on probe tip gently during shutdown maintenance, avoid scratching the probe sensing surface. Regular trending analysis of gap voltage and vibration data helps to find abnormal probe drift and cable aging at an early stage, prevent false alarm and ensure reliable machinery protection.
