โœฆ Synopsis

Two simple methods for the calibration of pressure transducers in the range 0 to 10 Pa are compared. One relies on water displaced by known weights and the other uses helium in an inverted U-tube. The slopes of the calibration curves determined with the two methodsagreed to better than 0.25% while the standard deviation of a typical calibration curve was better than 0.005 Pa.

Laboratory and field experiments demonstrated that solid state pressure transducers are accurate and reliable devices for frequent measurements of soil suction. However, each transducer had to be individually calibrated before use and a hanging column procedure designed for this purpose is described
