Frequently Asked Questions (FAQ)
-
How does the PR6424/118-100 detect shaft movement?
It uses the eddy current principle, sensing changes in the electromagnetic field caused by a conductive target moving near the sensor head. -
What type of output does the sensor provide?
It outputs a voltage proportional to displacement, which can be conditioned by a compatible converter. -
What is the sensor’s frequency range?
The sensor operates from DC up to 10 kHz, suitable for static and dynamic monitoring. -
Can it measure both radial and axial movements?
It is designed primarily for radial displacement measurement. Axial changes may influence readings slightly. -
How is accuracy maintained in noisy environments?
Shielded coaxial cable and proper grounding, along with the stainless steel housing, minimize interference. -
Is it suitable for predictive maintenance?
Yes, it can monitor vibration trends and detect early signs of unbalance or misalignment. -
How does it interface with monitoring systems?
Through a CON021 or CON041 converter, which provides power and conditions the output for integration. -
What target materials can it detect?
It measures conductive materials like steel or metal alloys. Non-conductive targets cannot be measured. -
Can it provide real-time data for protection systems?
Yes, it delivers continuous displacement and vibration data for automated monitoring and alarms. -
What happens if the sensor connection fails?
Converters can detect faults such as open or short circuits and alert operators.
