ABSTRACT:
A battery powered wireless fluid pressure sensor has a sealed chamber which can be vented to the outside atmosphere through a re-sealable reference port to allow a user to set the reference atmosphere inside the pressure sensor enabling the pressure sensor to provide absolute, gauge and true gauge pressure readings. The sensor calculates and transmits the fluid pressure taking into account the temperature of the pressure transducer, the temperature of the electronic devices and the barometric pressure inside the sealed chamber to provide accurate pressure measurements over a wide range of operating conditions.
