Abstract: A pressure measurement system may provide ready manufacturing, reliable operation, and/or enhanced performance by using a circuit board housing. In particular implementations, a pressure measurement system includes a pressure inlet joint, a pressure detecting component, a circuit board, and a circuit board housing. The pressure detecting component is coupled to the pressure inlet joint, which is adapted to introduce a pressure of a fluid. The circuit board is coupled to the pressure detecting component and is operable to condition an electrical signal from the pressure detecting component. The circuit board housing at least partially encloses the pressure detecting component and is adapted to engage the circuit board. The circuit board housing has a substantially cylindrical shape and includes a larger diameter section and a smaller diameter section, the smaller diameter section coupled to the pressure inlet joint, the circuit board located at least in part in the larger diameter section.

Abstract: A system and method for pressure measurement may include the ability to readily produce a pressure measurement system. In one general aspect, a process for producing a pressure measurement system includes providing an assembly including a stem, a pressure detector, and a first circuit board. The pressure detector is operable to generate a signal based on pressure introduced through the stem, and the circuit board is operable to condition the signal. The process also includes compensating the assembly, determining a signal output type for a pressure measurement system that will include the assembly, and installing a second circuit board that produces the signal output type without materially affecting the compensation.

Abstract: A dual range dynamic pressure differential generator for use at low pressures using a differential over a variable valve for a first stage pressure differential and the differential over a flow accelerator for a second stage pressure differential. The differential over the variable valve is useful for higher pressure differentials while the differential created over the flow accelerator is useful for a lower range pressure differential, although the two ranges may overlap.

Abstract: A compact, portable and NIST traceable pressure source dynamically generates very low pressures includes at least one adjustable valves in-line with a fluid, such as air, flowing through the valve. A differential pressure is created across a pressure control device downstream from the valve. The differential pressure varies depending on the volume of the gas flow and the amount of resistance to the gas flow. The pressure generating device utilizes a miniature pump to create a pressure, or, alternatively, a vacuum, that causes gas flow. The pressure generating device is compact and capable of providing a very low and stable differential pressure by using a dynamic flow that compensates for temperature changes and volume changes. The compact module may be configured as a plug-in module for existing handheld calibrators for operator ease of use.
