SL EVO: Long-term Stability Engineered Into Every Reading
A second diaphragm continuously measures atmospheric pressure, fully sealed off from the condensation, moisture, dust, and buildup that cause conventional sensors to drift.
- Two coupled diaphragms and two RTD temperature sensors work in tandem for stable, accurate output
- Fully closed and hermetically sealed measurement cell with no direct contact to the atmosphere
- Integrated temperature compensation and tank linearization with direct output of volume, level or pressure, even for tanks with complex geometries

The Conventional Approach
Conventional sensors equalize atmospheric pressure through an open vent, creating a direct path for condensation, moisture, dust, and buildup.

The SL EVO Way: A Dual Diaphragm
The SL EVO replaces the traditional atmospheric vent with a sealed reference diaphragm, eliminating a common pathway for moisture ingress and condensation-related measurement drift.

Goodbye Drift
No more re-zeroing for humidity swings or condensation. The SL EVO holds its accuracy through the conditions that throw conventional sensors off.
