Fluid pressure sensor
A sensor includes a port body which defines an axial passage for receiving fluid. An electrical connector extends through an opening in the port body near a crimp portion opposite the axial passage and forms an upper seal with the port body. Within the interior of the port body, a support ring and base cover form a cavity which retains a sensing element. The sensing element is exposed to the fluid within the axial passage and determines the pressure. An annular seal is retained by the base cover. The crimp portion of the port body is crimped to provide an upper seal and apply a force on the components within the interior, pinching the annular seal between the sensing element and the base of the port body to create a lower seal.
DIGITAL PRESSURE SENSOR
A digital pressure sensor includes a substrate, a pressure sensing structure configured for measuring a pressure of an object to be measured, a signal processing chip configured for receiving a sensing signal of the pressure sensing structure, and a rubber cover having an opening through which the pressure is sensed. The pressure sensing structure and the signal processing chip are mounted on the substrate. The signal processing chip has an analog-digital conversion module that converts the sensing signal output by the pressure sensing structure into a digital signal and outputs the digital signal. The signal processing chip is electrically connected to the substrate. The substrate and the rubber cover are connected to each other and form a mounting cavity for holding the pressure sensing structure and the signal processing chip.
Device for Checking the Function of an Aortic Valve
The invention relates to a device for testing the functioning of an aortic valve by placing the device on the free end of a cylindrical tubular prosthesis inserted into the aorta, said tubular prosthesis being connected, with its other end, to the aortic wall in the region of the aortic valve. According to the invention, the device consists of a multi-part housing provided with at least one through-flow channel for a control liquid, the housing being provided, on its lower side facing the free end of the tubular prosthesis, with a peripheral sealing device that can be placed around the edge of the tubular prosthesis, and at least one pressure-measuring sensor and at least one optical sensor element for video recording being arranged on the lower side.
Rectangular snap fit pressure sensor unit
An apparatus includes a base assembly, a gasket and a housing assembly. The base assembly may have a locking feature and a bearing feature. The locking feature may have a first passage in communication with an exterior of the apparatus. The gasket may be disposed on the base assembly and may have (i) a base portion, (ii) a column portion and (iii) a second passage in communication with the first passage. The housing assembly may have a sealing feature and may be configured to hold a sensor. The sealing feature (a) may mate with the bearing feature and (b) may compress the base portion of the gasket. The sensor (a) may seal to the column portion of the gasket and (b) may be in communication with the exterior of the apparatus through the first passage and the second passage.
Device for measuring the pressure and temperature of fluids
A device for measuring the pressure and temperature of fluids is provided, which has a temperature-sensitive element and a pressure-sensitive cell which are arranged connected to an electronic circuit, connected to which, in turn, are terminals of a connector by which a metal body is closed, in which the element and the cell are housed; the cell being housed in a cavity defined on one side of a plastic body through which electric conductors pass, which connect the element to the electronic circuit; the cell resting on a seal disposed between the cell and the base of the cavity, a wedge element placed over the cell which rests against the cell to compress the seal to thereby provide a seal around the mouth of a conduit through which the pressure of the fluid to be controlled is transmitted onto the cell.
SENSOR ASSEMBLIES AND METHODS OF MAKING SENSOR ASSEMBLIES
A sensor assembly includes a mounting portion arranged to support a sensing device, a thermal shunt portion extending from the mounting portion, and a housing portion. The housing portion extends from the thermal shunt portion and is arranged on a side of the thermal shunt portion opposite the mounting portion to limit temperature of a sensor connector fixed to the housing portion of the sensor assembly. Gas turbine engines having sensor assemblies and methods of making sensor assemblies are also described.
CRASH PRESSURE SENSOR
A pressure sensor for being mounted in a vehicle door includes a housing, a pressure transducer, an elastomeric connector, and electrical conductors for facilitating an electrical connection to the pressure sensor. The pressure transducer is mounted in the housing adjacent the elastomeric connector. The housing is configured to exert a force that presses the pressure transducer against the elastomeric connector. The elastomeric connector comprises electrically conductive regions configured to be pressed against electrical contacts of the pressure transducer and the electrical conductors to establish and maintain an electrical connection between the pressure transducer and the electrical conductors.
HIGH PRESSURE CAPSULE AND HEADER FOR PROCESS FLUID PRESSURE TRANSMITTER
A pressure capsule/header assembly for a process fluid pressure transmitter is provided. An isolator plug has an isolation diaphragm at a first end thereof and a second end spaced from the first end. The isolator plug has a fill fluid passageway fluidically coupling the first end to the second end. A header has a first end configured to carry a pressure sensor and a second end spaced from the first end. The header has at least one electrical interconnect extending from the first end to the second end. A biaxial support ring is disposed about an outer surface of the header. The biaxial support ring and the header define a tapered interference interface therebetween. The header is welded to the isolator plug at a first weld and the biaxial support ring is welded to the isolator plug at a location that is spaced from the second end of the header.
Pressure sensor with a communicating passage in a straight line
A pressure sensor with a communicating passage in a straight line. The pressure sensor includes a main body housing having an inner space and having a connector part provided for connection with an outside thereof. In the main body housing, the first end of a terminal is located in the inner space and the second end thereof is located in the connector part. A substrate is provided in the inner space of the main body housing and on which a sensing element is mounted, a cover housing coupled to the main body housing and comprising a seal configured to be in close contact with the main body housing and with edges of one surface of the sensing element. A communicating passage communicates with the inner space in a straight line, and thus communicates with one surface of the sensing element at a downstream side thereof.
Draft range transmitter enclosure
A method and structure which provide an ambient pressure measurement that is unaffected by wind and localized environmental conditions. A draft range pressure transmitter is enclosed inside an enclosure which is resistant to wind and other transient localize environmental conditions. A vent cap allows slow air movement through a wall of the enclosure and forms a still air chamber for the transmitter. The pressure inside the enclosure changes at the same rate as the barometric pressure but is unaffected by wind or wind gusts.
