摘要： An integrated seal and diaphragm member for a pressure sensor assembly may include a diaphragm portion and a seal portion integral with the diaphragm portion. In some cases, the integrated seal and diaphragm member includes one or more retention features integral with the diaphragm portion and/or the seal portion. In some cases, the seal portion may be thicker than the diaphragm portion and may extend around the perimeter of the diaphragm portion. In some instances, the seal portion may be configured to deform to form a seal with a pressure port of an external component or device without causing the diaphragm portion to move toward the pressure port in any significant way.

摘要： A purpose of the present invention is to provide a pressure sensor that uses a pressure detection element, the pressure detection element using the piezoresistive effect or similar, wherein the pressure sensor reduces distortion of the pressure detection element due to temperature changes, and allows accuracy to be increased and temperature responsiveness to be improved. A pressure sensor (100) according to the present invention includes: a pressure detection element (126) that detects the pressure of a fluid; a support member (125) that supports the pressure detection element (126); and an adhesive layer (125A) that is formed by coating an adhesive agent, and adheres and fixes the pressure detection element (126) and the support member (125), the pressure sensor being characterized in that the adhesive layer (125A) is configured from two layers, an initial curing layer (125A1) and a chip mount curing layer (125A2).

摘要： A pressure sensor assembly for use in sensing a pressure of a process fluid in a high temperature environment includes an elongate sensor housing configured to be exposed to the process fluid and having a cavity formed therein. A pressure sensor is positioned in the cavity of the elongate sensor housing. The pressure sensor has at least one diaphragm that deflects in response to applied pressure and includes an electrical component having an electrical property which changes as a function of deflection of the at least one diaphragm which is indicative of applied pressure. A flexible membrane in contact with the at least one diaphragm is disposed to seal at least a portion of the cavity of the sensor housing from the process fluid and flexes in response to pressure applied by the process fluid to thereby cause deflection of the at least one diaphragm.

摘要： A sensor element for recording at least one property of a fluid medium. The sensor element includes at least one housing that forms at least one wall of at least one flow channel that can be traversed by the flow of the fluid medium. In the wall, at least one pressure tap branches off from the flow channel. At least one pressure sensor for recording a pressure of the fluid medium is configured in the pressure tap. Provided in the wall is at least one outflow contour that at least partially surrounds an orifice of the pressure tap and is adapted for diverting impurities flowing along the wall away from the orifice of the pressure tap.

摘要： Advantageous mounting flanges for measuring devices and related methods of use are provided. The present disclosure provides advantageous mounting flanges configured to be mounted to measuring devices/instruments (e.g., pressure or temperature measuring devices/instruments), and related methods of use. More particularly, the present disclosure provides advantageous systems/methods for the design and use of user-friendly press-on mounting flanges configured to be mounted to pressure and temperature instruments (e.g., to the case of pressure or temperature gauges) to allow the instruments to be secured to a supporting structure (e.g., to a panel) via the mounting flanges. Disclosed herein is an advantageous mounting flange configured to be mounted to a case of a measuring device/gauge, thereby allowing the measuring device/gauge to be mounted to and held in a panel via the mounting flange. As such, the gauge case mounting flange is configured to hold the measuring gauge in place in the panel.
