Frequently Asked Questions (FAQ)

Q1: What is the measurement principle of this probe?
A1: It uses eddy-current sensing to convert gap distance into a proportional AC voltage.

Q2: Can I use a longer cable than 2 m?
A2: Yes—models with 3 m, 6 m, or custom lengths are available; refer to your cable-length variant.

Q3: How do I terminate the probe?
A3: It terminates with a 10-pin MIL-C-26482 stainless-steel connector matching 3300 XL cards.

Q4: What’s the typical gap setpoint?
A4: Recommended operating gap is 0.25–1.0 mm for optimal linearity and sensitivity.

Q5: Is the cable shield grounded?
A5: Yes, the integrated spring assembly provides reliable grounding to the probe body.

Q6: What maintenance does the probe require?
A6: Minimal—periodic inspection of the spring assembly and connector seals suffices.

Q7: Can it withstand shaft rubs?
A7: It’s designed to tolerate occasional contact at low speed but should not be driven into hard rubs.

Q8: What environmental ratings does it have?
A8: Rated for –40 °C to +120 °C, 100 g shock, and meets EMI/EMC IEC standards.

Q9: How is linearity specified?
A9: Linearity is typically better than 1% full-scale across the selected gap range.

Q10: Where can I get calibration certificates?
A10: ABB/Baker Hughes service centers provide NIST-traceable calibration upon request.
