Abstract
A pressure sensing device is configured for measuring water pressure in a soil medium, and includes a sensor housing and a pressure sensor. The sensor housing is adapted with a sensor cavity delimited by an enveloping surface. The sensor housing is provided with a selective passage for water between an outer surface of the sensor housing and the sensor cavity. The pressure sensor is arranged within the sensor cavity for measurement of a water pressure within the sensor cavity. The pressure sensing device includes an antimicrobial substance for preventing microbial gas production in the sensor cavity.
