The hydraulic TOR-IDRA/CE load cell has been designed to be placed at the base of structures of armor to measure the load they transmit to their foot . Such control is essential to ensure the safety of permanent support works.
The cell consists of two steel plates of circular shape, machined and welded together in such a way as to create an interspace filled by a special oil and connected to an electric transducer which transforms every variation of pressure acting on the lung in a variation of signal electric with standard output 4 to 20 mA.
