Concrete stress cell

The concrete stress cell is used for measuring the stress in, for example, shotcrete and structural concrete. The measuring body consists of two stainless-steel and flexible steel plates separated by hydraulic oil. The pressure in the hydraulic oil is measured off with an integrated pressure gauge.

 

The cell is prepared so that further oil can be added in order to compensate for shrinking displacements from curing. Sensors are available in versions for radial and tangential measurement. In the case of fully-automatic measuring, measurement data can be collected automatically by our data loggers and presented online on the Internet in our web system, where alarms are received and access is given to measurement values that are presented in a clear and effective way.
