Theoretical and experimental studies of a novel cone-jet sensor

Modeling of a novel cone-jet sensor using two-dimensional (2-D) finite elem ent analysis was investigated for dimensional measurement. Theoretical and experimental studies demonstrated that a cone-jet sensor supplied with air can be used to accurately measure displacement, and its work range of 1.5 t o 4.2 mm is some ten times greater than a simple back-pressure sensor. It i s anticipated that this type of sensor will rind wide applications in manuf acturing industry due to its wider working range, high precision, and other features.
