PLLG D01 Water level sensor
Measures groundwater levels in observation boreholes. Transmits readings over RS-485 for long-term monitoring of foundations, hydraulic facilities, and slopes.
Application and connection
Submerged in an open observation borehole for long-term groundwater level measurements. Suitable for geotechnical monitoring, hydraulic structures, and landslide slopes.
The D01 electronic unit is built into the sensor. It communicates with the acquisition system over RS-485 / Modbus. Selection accounts for pressure range, atmospheric pressure compensation, and required measurement error.
