A one piece needle and diaphragm system and method configured to measure in-cylinder pressure attributes is disclosed. The pressure monitoring diaphragm can also be configured to slide over the one piece needle and a housing assembly, thus eliminating an additional housing component and a welding operation from the current state of the art. Additionally, the one piece needle and diaphragm system can be used to measure both static and dynamic pressures in various combustion engine applications.
