Quick Detail

Description

The 21504-000-024-10-02 Proximity Sensor Probe is a high-performance eddy current proximity sensor probe designed for industrial automation and rotating machinery condition monitoring. With a nominal 8 mm probe diameter, this proximity sensor probe delivers precise non-contact displacement measurement within a typical range of up to 2.0 mm, making it suitable for shaft vibration, position, and runout monitoring. The probe features a stainless steel case and a PPS probe tip, ensuring mechanical strength, chemical stability, and long service life in harsh automation environments. Operating reliably across a wide temperature range from −35 °C to +177 °C, the 21504-000-024-10-02 proximity sensor probe integrates seamlessly with matched-impedance industrial extension cables and proximity monitoring systems. Its analog voltage output and sensitivity of approximately 7.87 mV/µm support high-resolution signal acquisition in automated control and protection systems, improving machine availability and predictive maintenance efficiency.

Applications

1. Turbine Shaft Monitoring

The 21504-000-024-10-02 proximity sensor probe is ideal for monitoring high-speed turbine shafts, providing real-time displacement measurements up to 2.0 mm. Its vibration-resistant design ensures reliable operation in environments with high rotational speeds, helping to detect imbalance or misalignment early and reduce unplanned downtime.

2. Pump and Compressor Vibration Analysis

In centrifugal pumps and compressors, precise shaft position and vibration data are critical. The probe’s analog voltage output and sensitivity of 7.87 mV/µm allow integration into predictive maintenance systems to track wear, bearing clearance, and operational anomalies in industrial automation setups.

3. Motor and Generator Condition Monitoring

Used in industrial motors and generators, this probe tracks rotor displacement and eccentricity, helping to prevent mechanical failures. Its stainless steel case and PPS tip provide chemical and mechanical resistance, suitable for continuous operation in oil- and moisture-rich environments.

4. Manufacturing Automation and Robotics

The probe supports automated machinery requiring precise motion feedback. Its 8 mm diameter and 100 mm total length make it compatible with tight installation spaces while maintaining high accuracy in positioning and displacement measurement.

5. Petrochemical and Refinery Equipment

For pumps, compressors, and mixers in petrochemical plants, the probe’s wide operating temperature range (−35 °C to +177 °C) ensures reliable measurement in high-heat or cold environments. Real-time displacement data improves process control and safety compliance.
