Long strokes bring four simultaneous constraints — amplified absolute error, reduced update rate, rigidity and transport — and a choice between the flexible and segmented routes.
Build the error budget before picking specifications: compress the range, separate resolution from repeatability, and account for update rate and thermal drift.
Certification is a prerequisite, not paperwork to patch together before delivery — the positioning of four systems and a seven-step verification process.
Three retrofit routes that leave the cylinder intact, six items to measure before starting, signal interfacing options, and four common mechanical installation pitfalls.
Five parameter groups — range, the three accuracy terms, temperature, protection and interface — each with the correct way to read it and the consequences of misreading it.
A four-step calculation method — fix the stroke, the mounting, the environment and the output — plus a pre-order selection checklist you can tick off directly.
Decided by the time budget of three quantities — sensor update period, bus cycle time and controller cycle — with a comparison of synchronization capability by fieldbus.
Pressure selection is based on the system pressure peak, not on the steady-state working pressure. Align by series: Series 16 is 530 bar peak, Series 17 is 600 bar, Series 19 in-cylinder is 600 bar.
The zone classification determines which protection types are permitted, and three further items must be checked: equipment protection level, gas group and temperature class.
The rod is limited by oil temperature and the electronics head by ambient temperature; the two boundaries are independent, and exceeding either one causes failure.
Comparing the selection boundary between magnetostrictive sensors and potentiometric resistive scales in terms of sensing mechanism, failure mode, protection capability and TCO composition.
Capacitive and eddy-current sensors measure a millimetre-scale gap; magnetostrictive sensors measure absolute position along a stroke — they are not solutions to the same problem.
