Reading the three reinforced environmental ratings of Series 13 for mobile hydraulics, and how head-integrated mounting differs from a Series 16/17 deep-bore cylinder.
The three-section structure of general-purpose Series 12, with 120 / 121 resolution written separately — the default choice when pressure, explosion protection or heavy vibration impose no constraints.
Differences between intrinsic safety, flameproof and dust protection, applicable zones, and deployment of the intrinsic-safety magnetostrictive 17EX.
From injection molding and metallurgy to wind power and process equipment — typical industrial monitoring scenarios for magnetostrictive displacement/position sensors, compared with contact-type solutions, plus explosion-protection deployment essentials.
Waveguide material selection, the advantages of iron-nickel alloy, and the engineering trade-offs between magnetostriction coefficient, temperature drift and service life.
The meaning of IP ratings, how water-ingress testing differs by level, IP69K for high-pressure washdown, and connector protection.
Why EMC is special for magnetostrictive sensors, how strong magnetic fields interfere, shielding and grounding countermeasures, and certification.
The role of factory calibration, how linearisation corrects non-linearity, dead-zone compensation, and why the on-site zero position still has to be set.
The four modules in the electronics head, how they map to fault symptoms, and a structured troubleshooting approach.
Magnet remanence, temperature coefficient, coaxial gap and anti-loosening essentials, plus high-temperature failure risks.
The difference between operating and storage temperature, the heat tolerance of the electronics head versus the rod, and common selection mistakes.
Multi-magnet measuring principle, Series 19 analogue dual-magnet minimum 76 mm, where it works and where it does not (not usable on multi-stage cylinders), plus fieldbus mapping configuration.
