  Wire scanners are the preferred proton beam profile measurement instruments. The scanner profile width measurement accuracy is unsurpassed and the scanners are applicable for a large beam intensity range. The transverse beam profile is sampled by the movement of a thin wire through the beam measuring impacting beam intensity and wire position. The equipment challenges are in the accurate measurement of the wire position during the high speed scan. The scan speed is maximized to cope with high intensity proton beams by limiting the energy deposition in the wire. In the contribution the operational scanner designs will be presented and their limits will be discussed. Novel approaches to overcome some limitations will be presented as well.
