Abstract
A high accuracy capacitive pressure transducer capable of performing measurements at a fixed temperature, with stability better than ±2 mK, in the temperature range of 15° C.-30° C. and which does not require the use of correction for thermal transpiration effect. The pressure transducer includes a vacuum gauge having a pressure sensor and a pressure sensor sheath, a temperature control unit secured in a cap; an aluminum block having a lower surface in contact with the pressure sensor sheath and an upper surface in contact with a main plate; and a temperature sensor located between the main plate and the upper surface of the aluminum block. The vacuum gauge is connected to a vacuum system by means of a connecting pipe.
