Design, Construction And Implementation Of Temperature Control In Vapor-Liquid Equilibrium Cell (VLE)

DCMG Bravo_Sanchez, MCJJ Martinez_Nolasco, JA Ramírez_Montañez

This article talks about the design and implementation of a thermal control in vapor-liquid equilibrium cell (VLE). Including integration of an amplifier circuit instrumentation for sensing stage by a thermocouple in conjunction with a full wave rectifier controlled. This controller used as a single-phase power line AC voltage which will be rectified to supply the voltage used by a thermal blanket and this transform electrical to thermal energy. The temperature generated by the heater blanket will depend on the way to generate this contact with the surface to be heated and the insulation used. The display operation of the control signals will be on a computer with the LabVIEW platform using an Arduino UNO which function as a data acquisition card. EVL cells are important in obtaining thermodynamic properties.
