Abstract
A system to determine a temperature corrected pressure of a medium in a pressure transducer is disclosed. The system comprises a first circuitry to obtain a first value related to a vibration frequency of the vibration of a pressure sensitive vibration member; a second circuity to obtain a second value related to a vibration amplitude of the vibration of the vibration member; and a third circuity to use the first value and the second value to determine the temperature corrected pressure of the medium based on a predetermined relationship between the vibration frequency and the vibration amplitude.

A system to determine a temperature corrected pressure of a medium in a pressure transducer, the system comprising:
- a first circuitry to obtain a first value related to a vibration frequency of the vibration of a pressure sensitive vibration member;
- a second circuitry to obtain a second value related to a vibration amplitude of the vibration of the vibration member;
- and
- a third circuitry to use the first value and the second value to determine the temperature corrected pressure of the medium based on a pre-determined relationship between the vibration frequency and the vibration amplitude.
A method to determine a temperature corrected pressure of a medium in a pressure transducer, the method comprising:
- obtaining a first value related to a vibration frequency of the vibration of a vibration member, the vibration member configured to vibrate under an input of a pressure;
- obtaining a second value related to a vibration amplitude of the vibration of the vibration member;
- and
- using the first value and the second value to determine the temperature corrected pressure of the medium based on a predetermined relationship between the vibration frequency and the vibration amplitude.
A non-transitory computer readable medium containing instructions, the instructions when executed, cause at least one processor to perform a process to determine a temperature corrected pressure of a medium in a pressure transducer, the process comprising:
- obtaining a first value related to a vibration frequency of the vibration of a vibration member, the vibration member configured to vibrate under an input of a pressure;
- obtaining a second value related to a vibration amplitude of the vibration of the vibration member;
- and
- using the first value and the second value to determine the temperature corrected pressure of the medium based on a predetermined relationship between the vibration frequency and the vibration amplitude.
