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