摘要： A capacitance-type pressure sensor having a reference capacitor plate and embodying a shield surrounding the lead wire and reference plate support assembly and maintained at substantially the same potential as the lead wire and reference plate. The shield extends substantially coplanar with the reference capacitor plate so that errors due to shunt capacitances are eliminated.
