Product Details: Bently Nevada 86691-04265-0435-15 is an eddy current proximity probe, belonging to the 86691 series non-contact transducer, used for relative shaft vibration and shaft displacement monitoring of rotating machinery. This Eddy Current Vibration Sensor works on eddy current principle, detecting the clearance between probe tip and rotating metal shaft, converting gap variation into high-frequency electrical signal, then matched with proximitor to transmit signal to rack monitoring modules. The probe tip is made of high-performance material, stable electromagnetic characteristic, good temperature stability, can adapt to high temperature environment near rotating shaft. According to ordering code 86691-04265-0435-15, it integrates fixed cable assembly, matched with designated cable length to form complete transducer system. During installation, control the static gap between probe tip and shaft surface within the linear range; improper gap will cause measurement error. The probe needs to be firmly locked by mounting thread, avoid vibration loosening. Signal cable should be separated from high voltage power cables to reduce electromagnetic interference. Regular maintenance checks probe tip wear, cable sheath damage and connector corrosion, and the whole system can perform sensor fault diagnosis to detect open circuit and short circuit. Widely used in power generation, petrochemical and heavy industrial fields, this Relative Shaft Vibration Transducer monitors turbines, centrifugal compressors, generators, fans and pumps, tracks shaft vibration and thrust position trend, protects bearing and rotor components, avoids catastrophic mechanical failure and unplanned equipment shutdown.
