Selection Suggestions and Precautions
Selection Suggestions
- Choose the EPRO PR6423/001-121+ if your application requires high-precision displacement/speed monitoring (0-12mm range) or operation in high-temperature/hazardous environments.
- Opt for this system if you are using EPRO monitoring systems or need seamless integration with PLCs/DCS via 4-20mA output, as it ensures reliable data transmission and compatibility.
- For rotating equipment with shaft diameters ≥50mm (e.g., turbines, large motors), the + offers optimal measurement accuracy and durability compared to smaller-range alternatives.
Precautions
- Install the EPRO PR6423/001-121+CON041 by qualified technicians trained in eddy-current sensor calibration to ensure proper probe alignment (gap setting) and signal integrity.
- Verify that the power supply matches the 24V DC requirement and use shielded cables for signal transmission to minimize electromagnetic interference (EMI) in industrial environments.
- Regularly clean the probe tip to remove dust, oil, or debris, as contamination can affect measurement accuracy and damage the sensor.
- Calibrate the system annually (per EPRO’s recommended schedule) to maintain ±0.1% accuracy, especially for critical applications like turbine monitoring.
- Avoid exposing the signal conditioner to excessive moisture or mechanical stress beyond its IP20 rating, and ensure proper ventilation to prevent overheating.
