Abstract: A field device (100) includes a capacitive gauge pressure sensor configured to measure a gage pressure of a process media, A sensor body (110) of the pressure sensor includes first and second chambers (112, 113). The second chamber (113) is under vacuum and forms a vacuum dielectric for the pressure sensor. An atmospheric reference port (180) is formed in the sensor body (110) and maintains the first chamber (112) in equilibrium with ambient atmospheric pressure. A process media inlet port (125) of the sensor is configured to couple to a process media source (120). The sensor includes a conductive deflectable diaphragm (130) between the second chamber (113) and the media inlet port (125). A capacitive plate (140) is disposed in the second chamber (113) in relation to the diaphragm (130) such that deflection of the diaphragm (130) generates a change in capacitance. The field device (100) also includes sensor circuitry (185) which generates a sensor signal indicative of the gage pressure of the process media (12O)5 and transmitter circuitry (190) which transmits information relative to the sensor signal over a process communication loop (195).

Abstract: An isolation assembly for connection to a process transmitter (50) and for mitigating high temperature effects of a process fluid includes a process coupling face (70) having an isolation diaphragm (72,74) configured to contact process fluid. A transmitter coupling (124) has a pressure coupling configured to couple to a pressure port of the process transmitter (50). A temperature isolation fluid conduit (120,122) extends between the process coupling face (70) and the transmitter coupling (124) and carries an isolation fluid which couples a pressure applied to the isolation diaphragm (74) to the pressure coupling to minimize high temperature effects of the process fluid on the process transmitter (50).

Abstract: Disclosed is a bi-directional differential pressure flow sensor (10) that is configured to establish a direction and flow rate of a fluid flow. The flow sensor (10) includes a flow restriction member (20), a differential pressure sensor (22), and processing electronics (50). The flow restriction member (20) is configured to produce a pressure drop when placed inline with the fluid flow. The differential pressure sensor (22) is embedded or integral with the flow restriction member and produces a differential pressure signal that is indicative of the pressure drop. The processing electronics (50) produces a flow rate signal that is indicative of the direction and flow rate of the fluid flow as a function of the differential pressure signal.

Abstract: Couche mince métallique (58) liant la surface de liaison à semiconducteurs (54, 56) d'une couche diaphragme (50) à la surface de liaison en céramique (44) d'un bloc support à module élevé (40). Cet agencement protège un diaphragme capteur de pression (60) des contraintes indésirables et en améliore la précision. Un passage (48) traversant le bloc support (40) couple la pression fluidique au diaphragme capteur (60) pour le faire dévier. Un couplage capacitif entre le diaphragme (60) et une plaque de condensateur (47) sur le bloc support (40) détecte la déviation et produit un signal de sortie représentant la pression.
