FAQ
-
What is the optimal gap voltage range for stable operation / the PR6424/104-101?
Typically maintained between 7 V and 11 V DC, adjustable through the driver module to suit the target shaft material. -
How does the sensor maintain accuracy in environments with strong electromagnetic fields?
A shielded low-noise coaxial cable and internal filtering provide high resistance to electromagnetic interference. -
What calibration method ensures consistent linearity across the measurement range?
Each probe undergoes precision factory calibration against certified displacement standards, ensuring ≤ ±0.25 % full-scale linearity. -
How can the PR6424/104-101 be configured to monitor both radial and axial displacement?
By installing two probes at orthogonal angles and integrating them with a dual-channel monitoring system for simultaneous measurement. -
Which shaft materials allow optimal eddy-current response with this sensor?
Most ferromagnetic alloys, including carbon steel and nickel-based alloys, provide excellent signal strength without surface preparation. -
What built-in features counteract temperature-induced measurement drift?
Temperature-compensating circuitry and high-grade probe materials stabilize readings from –35 °C to +180 °C. -
How should the sensor be grounded to avoid electrical noise and ground loops?
Use a single-point grounding scheme at the monitoring rack or driver module to maintain signal integrity. -
What sealing and housing characteristics support use in harsh industrial environments?
The stainless-steel probe body with IP67 protection resists moisture, dust, and aggressive industrial atmospheres. -
How does the probe’s frequency response benefit high-speed rotating machinery?
A 0–10 kHz bandwidth allows accurate tracking / rapid vibration changes in turbines and compressors. -
What certifications or precautions enable safe use in hazardous or explosive zones?
