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.

Abstract: Pressure sensor assemblies comprise a sensor body having a membrane within the body for placement in communication with a fluid from an external source and determining a pressure of the fluid. A support is connected with the body and includes a channel extending therethrough for receiving the fluid, wherein the channel is in fluid-flow communication with the membrane. A substrate is connected with the support and comprises a channel extending therethrough for receiving the fluid from an external source. The support may be formed from a material having a coefficient of thermal expansion that is between a coefficient of thermal expansion of the support and a coefficient of thermal expansion of the external fluid source connected with the substrate. One of the substrate or the support comprises a fluid pressure mitigation feature for mitigating the transmission of a pressure spike in the fluid to protect the sensor membrane.
