Abstract
The disclosed technology includes an oil-filled pressure transducer assembly and an oil-filled compensating sensing element disposed near one another and attached to a common housing. The oil-filled pressure transducer assembly may receive and measure pressure media via a first oil-filled cavity and a protective diagram in communication with the pressure media. The compensating sensing element may be isolated from the pressure media. In certain example implementations, the compensating sensing element is configured to measure certain common error phenomena that are also measured by the oil-filled pressure transducer assembly, for example, due to acceleration, temperature, and/or vibration. In certain implementations, the signal measured by the compensating sensing element may be subtracted from the signal measured by the oil-filled pressure transducer assembly to provide a compensated output signal.
