Qualitrol Company, LLC Datasheets for Gap Sensors and Feeler Gauges

Gap sensors and feeler gauges detect or measure the gap or clearance between two components or surfaces such as turbine blades tip clearance, nip or roller gap, lubricant gaps, weld seams, adhesive joints, extruder die gap, spark plug electrodes, mold spacing, and workpiece-fixture gap. Gap sensing products use mechanical feel (feeler gages), air pressure, optical, capacitance or other electronic technologies to sense gaps or clearance.
