摘要： A noninvasive system and method for measuring vacuum pressure in a fluid in accordance with the present invention generally includes a chamber with two interconnected diaphragms having different surface areas and a force transducer that makes contact with the smaller area diaphragm. When a pressure level less than atmospheric occurs inside the chamber, the smaller area diaphragm presses with a force on the force sensor. As the pressure level in the chamber decreases, the force on the sensor increases. The present system is intended for, but not limited to, use in a Phacoemulsification machine, where it will serve to measure the vacuum in a fluid without contaminating the fluid with previous uses of the system or with any components of the system which are unable to undergo a sterilization process.

摘要： Reliability and accuracy in a pressure measurement transmitter are provided by employing a plurality of absolute or gauge pressure sensors operating in conjunction with a differential pressure sensor. A method is also provided to perform diagnostics based upon the readings of the three pressure sensors. Further, should one of the three pressure sensors fail, a reasonable estimate of process pressure being measured by the failed sensor can be generated based upon the remaining two sensors.

摘要： A pressure header assembly has a closed front and back surface. The back surface has an aperture for accommodating a separate dual die pressure header. The dual die pressure header has an absolute and differential pressure sensor positioned thereon. A differential pressure port is located on a side surface of the pressure header assembly and is directed to a bore in the pressure header assembly. The bore contains an elongated tube which is positioned in the pressure header assembly and locked in place by means of a crush nut and locking nut assembly. One end of the tube is coupled to the differential pressure port, while the other end of the tube accommodates a differential pressure tube which is bent in an arcuate position and directed to the underside of the sensor of the differential sensor assembly mounted in the dual die pressure header. Suitable leads from the dual die pressure header assembly are directed to a terminal board which is mounted within a pressure transducer housing shell, which terminal board coacts with an outboard contact cap assembly forming the transducer. The pressure header assembly portion also contains extending tabs which have apertures for external mounting.

摘要： A pressure pickup, having a pressure chamber, which is located between a separating membrane and a platform. A pressure canal for hydraulic transmission of pressure to a measuring cell, includes, for dynamic overload protection, a Venturi throttle implemented by providing that the pressure canal has at least one segment whose flow cross section is variable. Such segment is preferably provided in the form of an annular canal. The flow cross section can be changed, for example, by an axial shifting of a conical inner wall relative to a complementary, conical outer wall, or by the deforming of an elastic inner or outer wall of the annular canal.

摘要： A pressure sensor includes a casing formed with a first case and a second case that has a pressure introduction hole for introducing a measurement object, a pressure sensing portion in the casing and a metal diaphragm disposed between an end face of the first case and a reception face of the second case. The measurement object is introduced into a subspace that is formed as an expanded end of the pressure introduction hole in the second case for measurement of pressure by transmitting the pressure through the diaphragm to the pressure sensing portion, and the pressure sensing hole has an orifice that reduces a cross-sectional area of the pressure sensing hole.
