CTRLPLUS
CTRLPLUS is a French manufacturer of optical metrology instruments for sand control screen inspection.
How do I prove sand control screens meet ISO 17824 / API specifications?
“You need a calibrated measurement of slot aperture, wire profile and aperture distribution, traceable and reproducible across batches. CTRL+ instruments output exactly that — a digital report per screen, audit-ready, with the same calibrated metric whether the measurement was taken on the production line, on the lab bench or in the field.”
View in the company profileWhat's the difference between wire wrap and slotted liner screens?
“Wire wrap screens are formed by triangular wedge wire wrapped around a perforated base pipe; the slot is the gap between adjacent wire turns. Slotted liners are tubes with longitudinal slots machined into the wall. Both require slot aperture qualification — and CTRL+ measures both.”
View in the company profileWhy use optical metrology instead of feeler gauges?
“A feeler gauge is destructive (deforms the slot at contact), single-point, undocumented and operator-dependent. Optical metrology is non-contact, samples the full slot profile, produces a digital trace, and removes operator bias.”
View in the company profileWhat slot apertures can CTRL+ instruments measure?
“From ~50 µm to ~2 mm — covering the full range of sand control screens (0.002 in to 0.080 in), water well screens, paper-machine screens and industrial filtration. Slot length, slot width, wire corner radius and wire half-angle are all measured.”
