Abstract
Pressure sensor assemblies comprise a sensor body having a sensing membrane and wherein a fluid is placed in communication with the membrane to determine a fluid pressure. A support is connected with the body and includes an opening for receiving the fluid from an external source, wherein the opening is in fluid-flow communication with the membrane. The pressure sensor comprises one or more elements disposed therein configured to mitigate transmission of a fluid pressure spike to the sensing membrane. The body or the support may have a pressure mitigating element, e.g., an internal channel, for receiving the fluid from the opening and transferring it to the membrane, wherein the channel may itself be configured to provide the desired protection against fluid pressure spikes, or may be connected with another internal element to provide such protection.
