SK-EP Vibrating Wire Earth Pressure Cell
Short Description:
Overview
The Enviko SK-EP vibrating wire earth pressure cell measures the contact pressure of fill against retaining walls, bedrock and other boundaries, as well as earth pressure within fill, embankments and soft foundations. An extra-thick back plate reduces the effect of point loads. A built-in temperature sensor records the temperature at the installation point.
Key Features
- Ten ranges from 0.35 to 7 MPa
- Extra-thick back plate to reduce point-load effects
- High accuracy, high sensitivity and long-term stability
- Excellent waterproofing for harsh environments
- 0.025% FS resolution and 30% overload capacity
- Built-in temperature sensor
Applications
- Contact pressure behind retaining walls
- Pressure on bedrock and foundation surfaces
- Earth pressure in fill and embankments
- Soft foundations and dams
