A pressure management system for sensors is provided. The system includes a sampling assembly. The sampling assembly is configured to hold a first portion of a test fluid. Further, the system includes at least one sensor disposed proximate to the sampling assembly. The sensor is configured to determine at least one property of the test fluid. The system also includes a housing that is disposed around the sampling assembly. The housing defines a fluid chamber that houses a balancing fluid. Furthermore, the system includes a flexible device disposed in the fluid chamber that draws a second portion of the test fluid. The flexible device is configured to balance pressure exerted by the test fluid on the sampling assembly by exerting pressure on the balancing fluid with the second portion of the test fluid.
