Desain Tensiometer dengan Metode Gelembung Maksimum Berbasis PC

Abstract

it has been designed a simple tensiometer with a maximum bubble pressure method based PC. The purpose of this study is to facilitate and simplify the measurement of the surface tension of the liquid. Tensiometer consists of a capillary tube of the former thermometer, pressure sensor, and a PC equipped with Labview software 2012. During the formation of bubbles due to the provision of the injection of pressure is monitored via a PC, so that the maximum bubble pressure can be determined. The results showed that the value of the validation is excellent based on the value of accuracy (95-99%) and the value of precision with 99%.
