Differential Pressure Transducer
The Rosemount 1221 senses pressure change through the use of a capacitive pressure sensing capsule. As pressure changes, a change in capacitance occurs. This change is detected and converted to a low impedance, high level DC voltage signal by the signal-conditioning circuitry in the unit.
