It consists of two longitudinal stainless steel plates, welded together around their periphery. The annular space between these plates is filled with de-aired glycol. A port and filter for pore water pressure measurement are located on one of the flat sides of the support plate behind the pressure sensitive section of the cell.
The pressure cell and the port for the pore water pressure are connected via stainless steel tubes to two pressure transducers integrated in the cell, typically vibrating wire, or pneumatic, or strain gauged if dynamic measurements are to be performed. A thermistor for temperature measurement is also incorporated.
