Hermetic Pressure Sensing Device

US Patent:
2006016, Jul 27, 2006
Filed:
Jan 17, 2006
Appl. No.:
11/333637
Inventors:
Alan Amore - Cumberland RI, US
Eric Giasson - Somerset MA, US
James Ogilvie - Cranston RI, US
Stephen Greene - Harmony RI, US
David Field - Attleboro MA, US
Andrew Willner - Attleboro MA, US
Vanvisa Attaset - Randallstown MD, US
International Classification:
G01L 9/12
US Classification:
073724000
Abstract:
A pressure sensing device () is shown having a ceramic capacitive sensing element () received in a chamber formed in a hexport housing (). The hexport housing has a fluid passageway () communicating with a recessed chamber () formed in a bottom wall circumscribed by an annular platform shoulder (). A thin flexible metal diaphragm () is hermetically attached to the bottom wall along the platform shoulder. A curable adhesive resin having a thermal coefficient of expansion and modulus of elasticity appropriately matching that of sensing element (), such as polyurethane, is cast between the sensing element () and the metal diaphragm () forming, when cured, a layer bonded to both members resulting in a sensor that is effective in monitoring negative as well as positive fluid pressures. In one embodiment a ring is used to define layer laterally and in a second embodiment an insulator sleeve () and shield sleeve () which receives pressure sensing element () each have an open end with an inwardly extending lip () that define layer laterally.

Differential Fluid Pressure Measurement Apparatus

US Patent:
7578194, Aug 25, 2009
Filed:
Feb 11, 2008
Appl. No.:
12/069522
Inventors:
Costas Hadjiloucas - Providence RI, US
Andrew Willner - Attleboro MA, US
Andrew Amatruda - Attleboro MA, US
George Krajewski - Coventry RI, US
Assignee:
Sensata Technologies, Inc. - Attleboro MA
International Classification:
G01L 13/02
US Classification:
73716, 73736
Abstract:
A differential liquid pressure sensor () has an upper housing () that mounts a connector portion () and receives in a recess a sense element module (). The sense element module is a body in which a generally U-shaped oil filled passageway () is formed with openings at opposite ends provided on respective first and second diaphragm mounting surfaces. A fluid pressure sense element, such as a piezoresistive sense element () is disposed in one of the passageway openings and flexible metal diaphragms () are mounted on the respective diaphragm mounting surfaces of the module facing a common direction. A lower housing () having first and second port connections for the respective diaphragms is disposed on the lower surface of the module.

Pressure Sensor

US Patent:
8129624, Mar 6, 2012
Filed:
May 27, 2010
Appl. No.:
12/788950
Inventors:
Andrew F. Willner - Attleboro MA, US
Lauren Snedeker - North Attleboro MA, US
Brian Wilkie - Tiverton RI, US
Gifford Plume - North Scituate RI, US
Prasanth Ambady - Providence RI, US
Assignee:
Sensata Technologies, Inc. - Attleboro MA
International Classification:
H05K 1/03
US Classification:
174255, 204450, 204601, 257295, 257529, 257668, 257751, 257787, 438282, 438597, 438622, 438624, 438674, 266212, 298901, 430322
Abstract:
A pressure sensor includes a sense element port, a support ring and a plurality of interference fit slits to provide a flexible interference fit between the sense element port and the support ring to form a substantially flush lap joint. The sensor also includes an electronics board inside the support ring and attached to planar mounting tabs which provide a stable mounting. Gel flow barriers protect electronics board features from unwanted non-conductive gel. Double-ended symmetrical, tapered contact springs provide manufacturing cost savings and contribute to improved alignment of an interface connector of the sensor.
