I. Overview:
Eddy current displacement sensor can be dynamic, non-contact measurement of the measured metal conductor and probe end face relative vibration displacement (such as shaft vibration, etc.).
Eddy current displacement sensor can static, non-contact measurement of the measured metal conductor and the probe face relative displacement (such as axial displacement, differential expansion, etc.).
In engineering vibration, rotating machinery and reciprocating machinery running status and operational failure analysis, the use of vibration monitoring is the most authoritative method, it is the most real time. The imbalance of the rotor, the two connected rotor misalignment, bearing wear, shaft cracks and rotor blades with the dynamic and static touch of the shell failure phenomenon is mainly reflected in the vibration amplitude, phase and frequency changes, these are Is the most critical information and is easy to measure.In engineering vibration, the analysis of the running state and running faults of rotating machinery and reciprocating running machinery, the use of vibration monitoring is an authoritative method, which has real time. Faults such as unbalance of the rotor, misalignment of the two connected rotors, bearing wear, shaft cracks, and dynamic and static rubbing of the rotor blades and the shell are mainly reflected in changes in the amplitude, phase, and frequency of vibration. Is the key information and is easy to measure.
Eddy current displacement sensor with long-term reliability, non-contact measurement, anti-interference ability, not affected by oil and other media, a wide range of applications, simple structure and so on. Used for long-term real-time monitoring of shaft vibration, axial displacement, shaft speed and expansion of the shell of a large rotating machine, which can effectively protect the safe operation of the equipment. Monitoring data can also be carried out trend analysis and fault diagnosis, in order to achieve the purpose of predictive maintenance and troubleshooting.
