Climatic Chamber for the Credibility Evaluation of Profilometric Measurements Construction and Control

Abstract

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