LOW PRESSURE TRANSDUCER WITH FERROFLUID

摘要

The low-pressure transducer with ferrofluid is a differential manometer with a U tube and an output electric signal. It consists of a U tube, a ferrofluid, magnetic pistons, magnetic cores and a coil system. The invention may be used to measure the low and very low pressure of gases and liquids in hundreds of H2O mm and tens of H2O mm. In addition, it can be used in the fine measurements of aerodynamic guns in the study of gas flow.
