    Sensor TechnologyPerformance SpecificationsElectrical SpecificationsEnvironmental ConsiderationsCalibrationApprovalsServiceabilityApplicationsResourcesThere are numerous technologies by which pressure transducers and sensors function. Some of the most widely used technologies include the following. Piston technologyuses a sealed piston/Cylinder to measure changes in pressure. Mechanical deflectionuses an elastic or flexible element to mechanically deflect with a change in pressure, for example a diaphragm, Bourdon tube, or bellows. Diaphragm Pressure Sensor Piezoelectric pressure sensorsmeasure dynamic and quasi-static pressures. The bi-directional transducers consist of metalized quartz or ceramic materials which have naturally occurring electrical properties. They are capable of converting stress into an electric potential and vice versa. The common modes of operation are charge mode, which generates a high-impedance charge output; and voltage mode, which uses an amplifier to convert the high-impedance charge into a low-impedance output voltage. The sensors can only be used for varying pressures. They are very rugged but require...
