Pressure measuring apparatus and method for measuring a pressure

The invention relates to a pressure measuring device having a in a pressure measuring chamber (36) arranged first sensor resonant circuit (20, 22) which is designed so that its resonance frequency has a first pressure dependence on a change of a pressure in the pressure measuring chamber (36) and sensitive to a change is another environmental parameter in the pressure measuring chamber (36); a second sensor resonant circuit (20, 22) which is designed so that its resonance frequency has a lower second pressure dependence on the change in the pressure in the pressure measuring chamber (36); and an interrogator tuned circuit (24) which is adapted to the resonance frequencies of the first sensor resonant circuit (20, 22) and said second sensor resonant circuit (20, 22) to determine and provide to an internal or external evaluation unit, so that by means of an evaluation of the resonant frequency of the first sensor resonant circuit (20, 22) for taking the resonant frequency of the second sensor resonant circuit (20, 22) as a reference pressure and / or the change in pressure in the pressure measuring chamber (36) is determinable. The invention further relates to a corresponding method for measuring a pressure.
