A transducer assembly configured for use with electrically charged or conductive media. The transducer assembly includes a pressure header made from a first material, a pressure chip mounted to the pressure header, an adapter made from a second material and attached to the pressure header, and a non-conductive body coupled to the adapter. The non-conductive body includes an opening configured for accepting the adapter and for securing the pressure header, the pressure chip, and the adapter within the opening of the non-conductive body. The non-conductive body is made from a third material that is different than the first material and the second material

An oil-fill pressure transducer including a flexible member configured to protect an isolation diaphragm and sensing element. The pressure transducer includes a sensing element mounted to the header, an isolation diaphragm mounted on the front side of the header, and adjacent to the sensing element such that an oil-fill cavity is defined between the sensing element and the isolation diaphragm. The flexible member is disposed adjacent to the isolation diaphragm and a retention member is disposed adjacent to the flexible member. A cavity in communication with the retention member is configured to transmit pressure media to the isolation diaphragm via the flexible member. The flexible member can include thru-holes. The flexible member may compress under an applied positive pressure change. The flexible member may temporarily separate from at least a portion of the isolation diaphragm under an applied negative pressure change.

This disclosure provides systems and methods for a fluid-filled pressure sensor assembly for higher pressure environments. A fluid-filled pressure sensor assembly may be adapted for coupling to a structure at a mating surface and may include a header; a pressure sensor coupled to the header; a diaphragm coupled to the header and configured for positioning forward of the mating surface so that a fluid region is disposed between the diaphragm and the pressure sensor; a fill hole coupled to the fluid region; a sealing element coupled to the fill hole and configured for positioning forward of the mating surface; and wherein during operation the first pressure applied at the diaphragm is substantially transferred by the fluid in the fluid region and the fill hole to an inner-side of the sealing element and the first pressure is about equivalent to a second pressure applied at an outer-side of the sealing element.

The invention is an improved sensor assembly including a housing; a first header and a second header coupled to the housing; a first transducer coupled to the first header and a second transducer coupled to the second header. The first transducer is configured to measure a first pressure to generate a first pressure signal. The second transducer is configured to measure a second pressure to generate a second pressure signal. The first transducer and the second transducer are positioned in the housing such that a first temperature of the first transducer is about equivalent to a second temperature of the second transducer during operation of the sensor assembly.

Sensor having thermal gradients

A pressure scanner assembly having at least one replaceable sensor plate, wherein each of the replaceable sensor plates has at least one pressure sensor adapted to transmit a signal substantially indicative of a sensed pressure condition. A memory chip, which stores correction coefficients for each of the pressure sensor to compensate for thermal errors, may be installed on each of the replaceable sensor plates. The signals from the pressure sensors are multiplexed and may be outputted in analog or digital form. The pressure scanner assemblies described herein have sensor plates that can be interchanged with other sensor plates of the same or different pressure range without disrupting the electronic configuration of the pressure scanner assembly or having to recalibrate and/or update the memory chip installed thereon.

A differential pressure transducer employing a coiled tube to eliminate varying pressure fluctuations is provided. In one embodiment, a method comprises receiving, at an inlet tube of a dampening chamber, a main pressure, wherein the main pressure includes a static pressure component and a dynamic pressure component; filtering, by the inlet tube, at least a portion of the dynamic pressure component of the main pressure; outputting, from the inlet tube, a first filtered main pressure; receiving, at a volume cavity of the dampening chamber, the first filtered main pressure, wherein the volume cavity is operatively coupled to the inlet tube; filtering, by the volume cavity, at least a portion of the dynamic pressure component of the first filtered main pressure; outputting, from the volume cavity, a second filtered main pressure; and wherein the dampening chamber is tuned to a predetermined resonance frequency.

Systems and method for controlling the flow and dissipation of thermal energy away from a weld between two components are provided. In one example embodiment, a structure may comprise a protrusion; a first component thermally coupled to the protrusion; a second component having a lower heat dissipation rate than the first component; a weld formed using a welding process to couple the protrusion to the second component, wherein the welding process generates thermal energy; and wherein the first component in combination with the protrusion dissipates the thermal energy from the welding process at about an equivalent rate as the second component.

Structure for tuning weld heat dissipation

A pressure belt comprising a flexible belt, and a flat pack assembly removably attached to the flexible belt, wherein each flat pack assembly comprises at least one sensing element. Further, each flat pack assembly also comprises a memory component associated with the sensing element thereon, wherein the memory component houses data specific to the corresponding sensing element. Unlike prior art structures, each flat pack assembly is individually removable. Therefore, if one sensing element malfunctions, it may be replaced by removing the flat pack assembly comprising the malfunctioning sensing element and swapping it out for a flat pack assembly comprising an operable sensing element. This is an improvement over the prior art as it eliminates the need for replacing and recalibrating the entire pressure belt when one sensing element malfunctions, which can be both time consuming and costly.
