Monitoring pH with HART communication

The paper presents experimental research related to pH measuring and to the design of a system of pH monitoring. The paper is structured on three parts. The first part presents the principle of measuring the pH of a solution matter, the transducer structure and of the adaptor used. The second part is dedicated to the experimental research effectuated aiming at the use of PACTware software environment for the configuration and checking of the pH transducer functioning by using the HART protocol. The last part of the article is destined to the presentation of the research work for the elaboration of the monitoring and control system using Labview software.
