Surface mounted ph sensor for cone penetration testing |
摘要 |
A surface-mounted pH sensor provides continuous pH profiling with depth during standard cone penetration testing (CPT). The pH sensor includes at least two electrodes, one being an antimony electrode and the other being a ceramic electrode. The electrodes are mounted to the shaft of a cone penetration device, and make contact with underground fluids during CPT. The antimony electrode, which functions as a measurement electrode, creates an exchange equilibrium between the hydrogen ions in the underground fluids and the ions of the antimony. This equilibrium creates a potential in the antimony electrode which is measured against the stable reference potential of the ceramic electrode. The resulting potential difference is indicative of the pH level of the underground fluids. |
