摘要： A variable capacitance measuring device can comprise a glass-ceramic insulator having a coefficient of thermal expansion that closely matches the coefficient of thermal expansion of a metallic materials used within the device. The glass-ceramic material may chemically bond to the surfaces of the metallic materials to provide a hermetic seal and eliminate the need for a separate glass seal or grooves within the electrode assembly. Additionally, a single-piece electrode assembly can be used instead of a separate electrode assembly (for the electrical feedthrough) and electrode. A shim may be used during the formation of the insulating material to reduce the likelihood of the insulator adhering to surfaces of the electrode portion during the manufacturing process. Also, separate bake-out and getter activation cycles may be combined into a single heat cycle.

摘要： A variable capacitance measuring device can comprise any one or more features in various different embodiments allow a reliable, compact device to be achieved. A capacitor electrode, a gettering housing, and pinch-off connector may be aligned along a common axis may reduce width dimensions without a substantial increase in length. Temperature-induced variations may be reduced by selecting materials that have coefficients of thermal expansion relatively closer to one another. Substantially varying topologies for ceramic-metal interfaces may reduce the likelihood of external contaminants from reaching the evacuated portion of the device. A tube can be used between the capacitor portion and a gettering housing to isolate external forces and getter activation heat from the sensor. The same tube also reduces heat loss from a heated sensor and protects the electronics from overheating. Embodiments also include processes for using and forming the devices.

摘要： Systems and methods for producing and delivering vapor are disclosed. A vaporizer tank containing a liquid may be heated such that liquid within the tank is heated and vapor generated. The flow of this vapor to a destination may then be regulated. Embodiments of the present invention may control the temperature of this liquid such that a saturated vapor condition is substantially maintained in the vaporizer tank. The vaporizer tank is coupled to a mass flow controller which regulates the delivery of the vapor to downstream components. By substantially maintaining the saturated vapor condition within the vaporizer tank the pressure of vapor at the mass flow controller can be substantially maintained and a stable and consistent flow rate of vapor achieved.

摘要： Embodiments of the present invention provide a diaphragm pressure gauge with an interface printed circuit board (“PCB”) contained in a reference pressure chamber of the diaphragm pressure gauge for receiving signals from one or more sensing elements in the reference pressure chamber. The sensing elements can comprise, for example, piezoelectric strain gauges, piezoresistive strain gauges, capacitor elements or other elements used in determining the deflection in the diaphragm. The interface PCB can be configured to connect the sensing elements to pass-through electrical connections in the housing of the reference pressure chamber. Thus, signals can be communicated from the sensing elements, through the interface board and out of the reference pressure chamber via the pass-through electrical connections.
