| Abstract: | The paper introduced a new way to measure the liquid surface tension coefficient by using silicon gas pressure sensor of type PT14. That new measuring way not only achieved non-capacitance measuring, but also improved the precision and stability of experimentation. The paper also expounded the theorem, measuring error and discussion. The conclusion of it manifestation: this way was not only easy and workable, but also had large value to be pushed ahead. |
