Climatic Chamber for the Credibility Evaluation of Profilometric Measurements

Abstract

The paper shows the construction and control of climatic chamber used for the credibility evaluation of profilometic measurements. The paper presents a control model using a PID controller and a solution for air circulation. Data regarding an influence of environmental temperatures changes on three-dimensional representation of the surface realized by means of a tactile profilometer was presented. This work shows the temperature characteristics of climatic chamber.
