An electrical readout system for tensiometers


, : An electrical readout system for tensiometers. Soil Science Society of America Journal 50(2): 494-496

Commercially available pressure transducers (PTs) and tensiometers were combined to continuously monitor in situ soil pore-water pressure. The transducers were calibrated over a range of 0 to -76.5 kPa and a temperature range from 5 to 40.degree.C. A single calibration equation corrected for zero offset and a small temperature-induced variation. Field temperature fluctuation between 10 and 30.degree.C had little effect on results from PTs connected to constant pressures of -5 and 11.5 kPa. Wetting fronts were easily mapped with outputs from tensiometers placed at three different depths. From these field data, prior water history and diurnal changes in soil pore-water pressure were easily obtained. Given variable field conditions, results from the PTs agreed well with closely-placed Bourdon gauge tensiometers.
