A high-precision pressure sensor with two or more pressure ranges is formed from multiple micro-electromechanical system (MEMS) pressure transducers mounted inside a housing and coupled to sense a pressurized fluid. The non-linear outputs of the MEMS pressure transducers are linearized by a corresponding number of processors, preferably DSPs, each processor being coupled to a corresponding MEMS pressure transducer and receiving the MEMS pressure transducer output signal there from. Each processor generates an applied pressure output signal, which is representative of a pressure applied to the MEMS pressure transducer, which is a linearized and digitized version of output signal from the MEMS pressure transducers. The data that is output from multiple processors, each of which outputs pressure data pertaining to a different range of pressures, is transmitted serially on a serial data bus.

Dual range high precision pressure sensor

Suspending a microelectromechanical system (MEMS) pressure sensing element inside a cavity using spring-like corrugations or serpentine crenellations, reduces thermally-mismatched mechanical stress on the sensing element. Overlaying the spring-like structures and the sensing element with a gel further reduces thermally-mismatched stress and vibrational dynamic stress.

Stress-isolated absolute pressure sensor

In a microelectromechanical system (MEMS) pressure sensor, thin and fragile bond wires that are used in the prior art to connect a MEMS pressure sensing element to an application specific integrated circuit (ASIC) for the input and output signals between these two chips are replaced by stacking the ASIC on the MEMS pressure sensing element and connecting each other using conductive vias formed in the ASIC. Gel used to protect the bond wires, ASIC and MEMS pressure sensing element can be eliminated if bond wires are no longer used. Stacking the ASIC on the MEMS pressure sensing element and connecting them using conductive vias enables a reduction in the size and cost of a housing in which the devices are placed and protected.

3D stacked piezoresistive pressure sensor

Electrical and mechanical noise in a microelectromechanical system (MEMS) pressure sensor are reduced by the symmetrical distribution of bond pads, conductive vias and interconnects and by the elimination of bond wires used in the prior art to connect a MEMS pressure sensing element to an application specific integrated circuit (ASIC). The bond wires are eliminated by using conductive vias to connect an ASIC to a MEMS pressure sensing element. Extraneous electrical noise is suppressed by conductive rings that surround output signal bond pads and a conductive loop that surrounds the conductive rings and bond pads. The conductive rings and loop are connected to a fixed voltage or ground potential.

A jointless pressure sensor port which includes a body portion, a flange portion integrally formed with the body portion, and a cylindrical portion integrally formed with and extending away from the flange portion. The port also includes an aperture having a first area, where the aperture is formed as part of the cylindrical portion. A channel is located along an axis and has at least one channel region. The channel at least partially extends through the cylindrical portion, the flange portion, and the body portion. A diaphragm includes a second area which is larger than the first area, the diaphragm also has a top surface and a bottom surface. A pressure sensor is disposed on the top surface, and the diaphragm is substantially perpendicular to the axis of the channel. The body portion, flange portion, and cylindrical portion form a jointless and seamless pressure sensor part.

Jointless pressure sensor port

Methods and systems for measuring pressure through a jointless pressure sensor port are disclosed, including permitting a substance to pass into a jointless pressure sensor port comprising an aperture, a channel, and a diaphragm having a larger area than the area of the aperture, allowing the substance to come into contact with the diaphragm resulting in a mechanical stress on the diaphragm, and measuring the mechanical stress to generate a signal indicative of the substance pressure.

A high pressure sensor mounting configuration () includes a cylindrical pressure sensor cavity (), an internally threaded collet (), and a housing (). The cylindrical pressure sensor cavity includes a convex conical open end and a first bearing surface (). The internally threaded collet includes a second bearing surface () that bears on the first bearing surface when the internally threaded collet is threaded onto a pressure port (), causing the convex conical open end () to bear on a concave conical mating surface of the pressure port. The housing captures the collet on the pressure sensor cavity.
