Abstract

Disclosed is a pressure transducer including a body made of a material having a first coefficient of thermal expansion, a fluidic inlet and a fluidic cavity enclosed by the body in fluidic communication with the fluidic inlet. The pressure transducer further includes a strain gauge including a resistive element in operable contact with the body. At least a portion of the resistive element made of a material having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion of the body. Disclosed further is a pressure transducer including a filler body located in a fluidic cavity of the pressure transducer configured to reduce adiabatic thermal effects on a transducer body. Disclosed are systems and methods incorporating the pressure transducers described herein.
