A pressure sensor, for example, employed by a medical injection system for monitoring blood pressure, is isolated from relatively high pressures by a volume of a compressible medium, preferably air, or other suitable gas. The volume fills an entirety of a cavity of a pressure transducer assembly, and is enclosed between a pressure transmission interface of the assembly and the pressure sensor. The pressure transducer assembly is integrated into a fluid circuit such that the pressure transmission interface is exposed to flow through the fluid circuit.
