The Hydraulic Load Cells are intended to be located at the base of reinforcement structures in order to measure the load transmitted to their base. Checks of this type are essential to guarantee the safety of temporary and permanent retaining structures. Load cells are generally installed at the foot of tunnels, below rib supports, bulkhead support struts, piles, etc, and are of a shape and size to simplify installation.
Our Hydraulic Load Cells consist of two circular steel plates, shaped and soldered together in such a way as to create an interspace which is filled with a special oil and connected to an electric transducer which converts each change of pressure on the cell into a variable electric signal with standard exit of 4 ÷ 20 mA (on request we can provide cells with vibrating wire sensor).
All sensor parts, including cables, are isolated and protected, in order to avoid concrete (or water) getting into the cell; circuits and sensors are resinated and protected in order to ensure the instrument still functions in the event of impact or immersion.
The reading of data provided by the electric pressure transducer is possible either using a portable unit or via automatic data acquisition system for continuous monitoring.
