摘要： A flush-mounted sensor measures the pressure of a fluid within a hollow conduit (26). A sensor head (18) edge-mounts an isolating diaphragm (12) responsive to the pressure of the fluid. The isolating diaphragm (12) has a small diameter, typically less than 1/4 inch, is adjacent the fluid in the conduit (26) to reduce the dead volume of fluid adjacent the diaphragm (12), formed of a material that is compatible with the fluid. A drive rod (14) mechanically couples the isolating diaphragm (12) to a second diaphragm (16) of a variable capacitor assembly (17). The second diaphragm (16) is also edge-mounted and produces a counterforce acting on the side of the isolating diaphragm (12) opposite the side adjacent the fluid. The force of the fluid pressure acting on the isolating diaphragm (12) is transmitted by the drive rod (14) to the second diaphragm (16) where changes in the capacitance correspond to changes in the pressure. In another form the isolating diaphragm is formed as a thin, non-circular portion of the conduit wall.

摘要： Un systeme de pesage (210) comprend un organe d'introduction de force, tel qu'un plateau de pesage (212) et une armature rigide (226). Une premiere liaison (110) effectue le couplage de l'armature (226) a un organe de reference ou enceinte (220) d'une maniere qui limite le mouvement de l'armature le long d'un axe de reference (216) fixe par rapport a l'organe de reference. En general cette liaison est particulierement resistante aux moments appliques. Une seconde liaison (160) effectue le couplage elastique de l'organe d'introduction de force (212) a l'armature (226), permettant une plage relativement grande de mouvements relatifs lineaires de ces elements. Un amortisseur de faible friction (218) est couple entre l'organe d'introduction de force (212) et l'organe de reference (220) pour amortir le mouvement relatif de l'organe d'introduction de force et de l'enceinte. Un transducteur de force (10) est couple entre l'armature (226) et l'organe de reference (220). Le transducteur (10) comprend une paire de surfaces complementaires opposees ayant une separation mutuelle qui est en relation avec la force appliquee au transducteur. Un detecteur de position (224) couple au transducteur (10) genere un signal representant la separation entre les surfaces complementaires opposees du transducteur.

摘要： A system for controlling pressure associated with a volume may comprising a pump and piston/cylinder assembly, both in fluid communication with a volume of a closed fluid system. In addition, the system may comprise an actuator operatively connected to the actuator and pump to control fluid flow and pressurization or depressurization of the volume and/or fluid flow system. The pump is activated to generate a first pressure level of the closed fluid system and when this first pressure level is reached the actuator is activated to drive the piston/cylinder assembly to reach a pressure set point from the first pressure level. The system may be used as a calibrator or a pressure controller for pressure differentials, gauge pressure or absolute pressure.

摘要： A capacitive pressure sensor (10) includes a conductive diaphragm (20) positioned between two pneumatically separate chambers (60, 64). The diaphragm is supported at its periphery by a concave base member (30). An electrode assembly (40) establishes a substantially planar conductive surface (42a) opposite to, and spaced apart by a nominal gap from, the conductive diaphragm. The electrode assembly includes the conductive surface and a single support element (44) secured to, and extending through the base member. A glass dielectric (46) fixes the support element to a collar (48) which may be welded, brazed, or soldered to the base member. The glass dielectric provides both mechanical support and high quality electric insulation between the electrode and the housing. By prefabricating the electrode support element with the collar and securing the collar to the housing after the dielectric has cured, problems associated with thermal expansion are avoided and the dimension of the nominal gap may be precisely controlled at low cost.

摘要： A compact force transducer (10) has at least one flexible beam (16, 18) mounted at one or both its ends to a force summing member (12, 14) or members. The force-to-be-measured is applied to the force summing member (12, 14) along a first axis (22) generally transverse to the beams to deform the beam elastically, without overstressing, through a displacement d. A sensor member (28, 30) carries a conductive surface (38) and is coupled to the beam member. In a parallelogram form, there are a parallel pair of beam members (16, 18) extending between two force summing members (12, 14) and a sensor member (28, 30) is secured to each beam member (16, 18) at or near its point of inflection. One sensor member (30) includes multiple arms (36, 36) that sandwich the other sensor member (28) to produce a linear, push-pull mode of operation. In alow cost cantilevered beam form, the sensor (28') is coupled to the beam (16') at the force summing member (14') in a parallel, spaced relationship. In a hybrid push-pull form, the transducer uses a two beam parallelogram construction with cantilevered sensors (28'', 30'') (1) coupled rigidly to each beam (16'', 18'') adjacent one force summing member (12'', 14'') with a hinge coupling (16''a, 18''a) between the beam and this one force summing member, and (2) extending generally in a parallel spaced relationship with respect to an associated one of the beams (16'', 18'').

摘要： An apparatus for measuring the pressure of a liquid column (36) enclosed within a pressurized tank or cell (37), and for deriving the height and/or density of the liquid column based on the measured pressure. The apparatus includes a first pressure sensor (38) for differentially measuring the pressure within the cell relative to a reference pressure at a first height (H1), and further includes a second pressure sensor (39) for differentially measuring the pressure within the cell relative to a reference pressure at a second height (H2). A feed back network (48) is operative to match the reference pressure to the pressure within the cell at one of the first and second heights. The feedback network ensures that the sensor detecting the one region is maintained at a zero or null differential pressure condition, enabling the use of a small dynamic range sensor.

摘要： A transducer measures the pressure of a fluid within a hollow conduit, typically one with a circular cross-section, having a central region that is deformed to a non-circular cross-section. This non-circular portion of the conduit displaces radially and repeatably without hysteresis in response to the pressure of the fluid in the conduit in a manner that corresponds to the pressure. A variable capacitor assembly (26), or a set of strain gauges (A, B, C, D) mounted on the exterior of the non-circular portion, produce an electrical signal proportional to the radial displacement or to the strain, respectively. In one capacitive form (26) a pair of electrodes (24) are mounted on opposite sides of the non-circular portion formed as free end portions of metallic sheet members with a central channel. In another capacitive form (26') electrodes (24') are mounted at one or both ends of lever arms which in turn are coupled to the non-circular portion with a set of flexure plates (34, 36) to produce a mechanical amplification of the radial displacement.

摘要： A linkage (160, 300) for constraining the motion of a reference member (162, 302) along a reference axis (164, 306) with a substantial degree of motion along this axis while exhibiting good resistance to side forces and moments as well as off-axis motions. In one form the linkage includes two pairs of flexure elements (168, 170 and 172, 174), each flexure element having a vertex end portion and at least one distal end portion. The flexure elements of each pair are connected so that their corresponding pairs of distal end portions are coupled to each other. Each of the coupled distal end portions is connected by a rigid link (176, 178) to the corresponding pair of connected distal end portions of the other pair of flexure elements so that the junction of the distal end portions of each coupled pair are separated by a predetermined distance in the direction of the reference axis. The vertex portions of corresponding ones of the flexure elements of each pair is connected to the reference member (162). The two vertex portions coupled to the reference member (162) are separated by the predetermined distance in the direction of the reference axis (164). The vertex portions of the other flexure elements are connected to the support member at points separated by the predetermined distance in the direction of the reference axis (164).
