THE INFLUENCE OF THE PROBES BRIGHTNESS SURFACES ABOUT THE DIMENSIONAL CONTROL PRECISION IN CASE OF THE USE OF NON CONTACT DISPLACEMENT TRANSDUCERS

Abstract

This paper presents a study regarding the high influence of the probes brightness surfaces about the linear characteristics displacement of an optical non contact transducer, produced by OMRON Company (Japan). Being known the functional and technical characteristics in the product guide, we took the problem by the point of view of the evaluation of the transducer functioning behavior in other conditions as microelectronics. It is known that the device can be successfully used for the small probes in ceramics, used in micro-electronics, which properties are that their reflexive surfaces are frosted. So, we purpose to observe the linear transducer characteristics varies in case of small probes having different properties (color, reflexivity of surfaces), in order decide in which domains ranges the transducer could be used for the dimensional control process and also to establish in which cases its use should be required.
