        • Small high-speed rotating machinery: Vibration and displacement monitoring of small centrifugal compressors, boosters, and high-speed pumps.
        • Bearing housing internal monitoring: Suitable for rolling bearings or small sliding bearing housings with extremely limited physical space.
        • Laboratory and test benches: Measuring minute clearance changes or analyzing shaft trajectories in precision R&D equipment.
        • Not OK Status Diagnosis: The system continuously monitors the electrical integrity of the circuit. If the probe coil is damaged, the cable is broken, or the connector is loose, the preamplifier will output an abnormal voltage signal, triggering the "Not OK" indicator on the monitoring system, thereby disabling alarms and preventing false trips due to sensor failure.
        • Gap Voltage Misalignment Monitoring: By observing the static voltage (usually installed at -10V DC), technicians can diagnose whether the bearings are excessively worn or whether the probe is loose or displaced.
        • Anti-interference protection: It has excellent electromagnetic shielding performance, which can effectively filter out electronic noise generated by motors or frequency converters, ensuring that the signal transmitted to the protection system is clean.
        • Gap Alignment: During installation, rotate the probe to adjust the distance from the shaft until the preamplifier output voltage reaches the center of the linear region (usually -10V).
        • Tightening and Preventing Loosening: 1/4-28 threads are fine; strictly adhere to the recommended torque during installation to prevent thread stripping due to overtightening. It is recommended to use a self-locking nut to prevent loosening during operation.
        • Connector Protection: When connecting extension cables, it is recommended to use a connector protector or silicone tape to prevent corrosive liquids or oil from seeping into the connector.
