Non Contact Displacement
For measurement of displacement without actual target contact, MicroStrain have a range of inductive sensors for very accurate close range measurements of metallic targets.
Capacitec manufacture a range of sensors for very accurate displacement sensing. By measuring the capacitance change between two adjacent conductive surfaces, these non-contact sensors can measure gaps and general displacements with excellent repeatability.
Acuity Lasers offer a range of non-contact laser sensors for measuring both near and far distance displacements. Please see our separate page on Laser Displacement or check out their web site.
