IFM measures air gaps with micro-metre precision
When a workpiece must be positioned accurately to within a fraction of a millimetre, or when it’s necessary to measure the surface roughness of an item, the new SDP110 air-gap sensor from IFM Electronic provides an effective and easily implemented solution. This novel sensor, which uses air flowing through a nozzle to measure the distance between the nozzle and the workpiece, has a resolution of 5µm, which is just one-tenth of the thickness of a typical human hair. Maximum measuring range is 400 µm.
