Epro PR6426-010-140+CON21 Status Monitoring Eddy Current Displacement Sensor
Epro PR6426-010-140+CON21 is a complete eddy current displacement sensor system, consisting of PR6426 probe, extension cable, and CON21 preamplifier. Based on the principle of non-contact measurement of eddy current, without the need for contact with the rotating shaft surface, physical quantities such as radial vibration, axial displacement, shaft eccentricity, and rotational speed of rotating machinery can be collected in real time. The preamplifier amplifies and linearizes the small gap change signals collected by the probe, outputs standard voltage signals, and transmits them to the TSI state monitoring system. PR6426-010-140+CON21 is used for online status monitoring, over limit alarm, and interlock protection of the unit to prevent damage to rotating equipment due to excessive vibration and ensure safe and stable operation of the unit.
Product Features
- Non contact measurement, the probe does not directly rub or wear against the shaft, has a long service life, and is suitable for long-term uninterrupted online monitoring.
- The measurement is not affected by oil, water vapor, or lubricating oil media, and is suitable for harsh working conditions inside the bearing box of the unit.
- High measurement resolution and good linearity, capable of capturing micro axis displacement and vibration changes at the micrometer level.
- The preamplifier comes with a built-in line fault diagnosis function, which can identify probe breakage, short circuit, cable abnormality, and output fault signals.
- Wide temperature working range, the probe can withstand high temperatures, meeting the high-temperature bearing environment of steam turbines and compressors.
- Double layer shielded cable design with strong electromagnetic interference resistance, suitable for strong electromagnetic fields in power plants and chemical industries.
- Modular solution, with probes, cables, and preamplifiers calibrated together to ensure measurement accuracy.
- Easy installation and debugging, with a threaded probe structure that facilitates on-site adjustment of installation clearances.
