A self calibrating differential pressure sensor having a pair of pressure transducers connected in fluid series with two on/off valves. The system can be calibrated to eliminate base line or zero shift and can also be used to measure other variable conditions, such as differential voltage between two voltage points or differential chemical concentrations between two concentration points.
