Frequently Asked Questions (FAQ)
Q1: What principle does the PR6426/010-140 use?
A1: It employs eddy-current induction to translate gap distance into a proportional AC voltage.
Q2: How do I terminate the sensor cable?
A2: The sensor uses a standard M12 8-pin male connector compatible with most condition monitors.
Q3: What is the optimal gap for this sensor?
A3: A gap between 0.5 mm and 2.5 mm yields the best linearity and sensitivity.
Q4: Can the sensor withstand high electromagnetic interference?
A4: Yes, its braided shield and integrated filtering provide robust EMI/RFI immunity.
Q5: What environments can it operate in?
A5: Rated for –40 °C to +125 °C and shock up to 50 g, it suits harsh industrial settings.
Q6: Does it require calibration?
A6: The sensor is factory-calibrated; periodic verification intervals depend on application and usage.
Q7: How does the probe’s 32 mm diameter benefit measurement?
A7: Larger tip diameter increases signal strength and stability over irregular or coarse targets.
Q8: What is the output signal type?
A8: It delivers a 0–10 V AC signal proportional to the measured gap.
