Electro-hydraulic load cells consist of stainless steel pad with a pressure transducer. The piston pad is realised by two plates welded together around their periphery and spaced apart by a narrow cavity saturated under high vacuum with de-aired oil to assure maximum rigidity; so that load is transmitted into a pressure measured by the pressure transducer.
They are specially designed for steel lining and struts monitoring.
Special twin distribution plates are available for application between not parallel surfaces.
