Soil-rock Interface Pressure Cell

View Related Products

The EPS-30V-I interface pressure cell is used to measure pressure between soil and rock or concrete interfaces. The pressure cell is designed similarly as EPS-30V-S, except a thicker diaphragm on rock/concrete side of the pressure pad, which minimizes point-loading effects.
