Existing displacement sensors of micrometers to sub-micron precision are expensive and have various limitations. This paper reports the design and development of a new contact type compact micro-displacement sensor of sub-micron precision for a fraction of the cost of commercial devices. The basic concept of the new sensor system applies a mechanical magnifying mechanism to magnify a ... https://www.diegojavierfares.com/quick-offer-Explore-Caravan-Scissor-Jack-ADR-Australian-Standard-1600Kg-CSJ1600-mega-choice/
