Services

Hydrostatic pressure is converted into an electrical signal by the membrane sensor. It consists of a silicon plate, separated from the fluid by membrane made of stainless steel. Movement of the membrane caused by pressure is transferred to the silicon plate, which changes resistance. Resistance change is converted into an electrical signal that is evaluated. Body of the converter is made of stainless steel, cable sheath is either PVC, silicone or teflon according to chemical composition of the measured medium.
