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 ofa 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 fillerbody 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.

Description

[0001] related application [0002] This application is a non-provisional patent application claiming priority to U.S. Provisional Patent Application No. 62 / 675,849, filed May 24, 2018, entitled "Pressure Transducer, System and Method," which The US Provisional Patent Application is hereby incorporated by reference. technical field [0003] The present invention generally relates to pressure transducers. More particularly, the present invention relates to pressure transducers configured to reduce thermal effects, liquid chromatography systems incorporating pressure transducers, and methods of reducing thermal effects on pressure transducers. Background technique [0004] A typical strain gauge pressure transducer consists of a complete Wheatstone bridge foil strain gauge mounted directly above a pressurized chamber with a suitable web thickness to allow Measurable deflection of the intermediate housing material. A strain gauge will generally have two active grids for meas...
