PLLG Pore pressure sensor
Measures water pressure between soil particles. Used to monitor seepage, ground foundations, dams, quarries, and landslide processes.

Application and connection
Measures pore water pressure within the soil mass. Applications include the hydrogeological regime of foundations, seepage through earth dams, stress development in quarries and mine workings, natural landslides, and automated geotechnical monitoring during construction.
Connects to CU-LoRaWAN, CU-GPRS, or CU-LTE modules for continuous acquisition, or to a portable SmartLogger for manual readings.
