Van Essen Diver Family

Pressure transducers with integrated data logger

Cost-effective and reliable, these compact groundwater data loggers provide accurate and reliable long-term measurements of water levels, temperature, and conductivity— essential data needed for effective water resource management, environmental remediation, mine dewatering, and slope stability. Van Essen Diver logging sensors are submersible pressure transducers and data loggers for long-term uninterrupted, real-time water level monitoring when submerged at a fixed level under the water surface. The pressure sensor measures the equivalent hydrostatic pressure of the water above the sensor diaphragm to calculate the total water depth. The Diver autonomously measures pressure and temperature and records them in its internal memory. The Diver is ideal for ground and surface water level applications. In addition to internal data storage, the Divers can be connected to Stevens’ data logger or data telemetry systems with the Diver-SDI SDI-12 output adapter, allowing the Diver to be used for real-time data monitoring applications. Manual data download in the field from a Diver’s internal storage can be done by utilizing the optional USB Interface Cable and connecting the diver directly to a desktop or laptop PC. All Divers have a 3-year warranty, up to 10 years battery life, and can be used from 300 m below to 5000 m above sea level.
