SGE Series | (SGE-25 / SGE-16 / SGE-25S / SGE-25C)
Aplisens
The Aplisens SGE Series hydrostatic level probes are submersible transmitters designed for accurate liquid level measurement in tanks, wells, and open water applications. Using hydrostatic pressure measurement, these probes provide reliable level data based on the height of the liquid column, making them ideal for continuous level monitoring in industrial and environmental systems.
Built around a piezoresistive silicon sensor with diaphragm isolation, the SGE Series delivers stable and repeatable measurement performance across a wide range of depths. The probe is submerged directly into the liquid, with pressure referenced to atmospheric conditions through a capillary integrated into the cable.
Available in multiple configurations, including narrow-diameter probes for piezometers and enhanced material options, the SGE Series is engineered for durability, long-term stability, and reliable operation in harsh environments.

Water wells, groundwater monitoring, tanks and vessels, wastewater systems, environmental monitoring, reservoirs, and industrial liquid storage systems

PERFORMANCE ADVANTAGES
Why the Aplisens SGE Series Performs Where It Counts
DIRECT LEVEL MEASUREMENT USING HYDROSTATIC PRINCIPLES
The SGE Series measures level based on hydrostatic pressure, providing a simple and reliable relationship between liquid height and pressure. This eliminates the need for complex mechanical systems and ensures consistent measurement performance.
HIGH ACCURACY WITH LONG-TERM STABILITY
With accuracy up to ±0.1% FSO and stable performance over time, these probes provide dependable level readings for both industrial and environmental monitoring applications.
DESIGNED FOR SUBMERSIBLE &
HARSH ENVIRONMENTS
The fully sealed IP68 construction allows the probe to operate continuously underwater, while stainless steel construction and optional corrosion-resistant materials ensure durability in aggressive media.
PROTECTION AGAINST ELECTRICAL DISTURBANCES
An integrated overvoltage protection circuit protects the probe from damage caused by electrical interference, lightning, and industrial power fluctuations.
