FAQ
Q: What is the difference between proximity transducers and accelerometers?
A: Proximity transducers measure shaft displacement (position), while accelerometers measure vibration. Both are complementary.
Q: Can I use this with non-steel shafts?
A: Requires conductive target material (steel, stainless steel, Inconel). Not compatible with ceramic or composite.
Q: How often should I recalibrate?
A: API 670 recommends recalibration every 5 years or after cable replacement.
