Patent number: 7270010Abstract: A pressure measurement system may provide ready manufacturing, reliable operation, and/or enhanced performance by using a circuit board housing. In particular implementations, a pressure measurement system includes a pressure inlet joint, a pressure detecting component, a circuit board, and a circuit board housing. The pressure detecting component is coupled to the pressure inlet joint, which is adapted to introduce a pressure of a fluid. The circuit board is coupled to the pressure detecting component and is operable to condition an electrical signal from the pressure detecting component. The circuit board housing at least partially encloses the pressure detecting component and is adapted to engage the circuit board. The circuit board housing has a substantially cylindrical shape and includes a larger diameter section and a smaller diameter section, the smaller diameter section coupled to the pressure inlet joint, the circuit board located at least in part in the larger diameter section.Type: GrantFiled: August 27, 2004Date of Patent: September 18, 2007Assignee: Ashcroft-Nagano, Inc.Inventors: Yoshikazu Kaneko, Shuji Shimada, Ikuhiro Yanagisawa, Yoshinori Wada, William Stephen Kosh, William J.

Patent number: 7263895Abstract: A fluid pressure sensor (1) for measuring the pressure of a fluid comprises a diaphragm portion (12) which is a strain generating body, a silicon oxide film (21) as an insulating film, and a strain gauge (20) made of crystalline silicon, and austenitic precipitation hardening type Fe—Ni heat-resisting steel excellent in mechanical strength and corrosion resistance is used for the diaphragm portion (12). The silicon oxide film (21) is formed with the internal stress thereof adjusted to the range from ?150 to 130 MPa. With this feature, the fluid pressure sensor (1) ensures high precision and reliability, and may be used even for measurement of a highly corrosive fluid.Type: GrantFiled: July 15, 2005Date of Patent: September 4, 2007Assignee: Nagano Keiki Co., Ltd.Inventors: Hiroshi Nagasaka, Takeshi Abe, Yoshikazu Kaneko

Patent number: 7252009Abstract: A system and method for pressure measurement may include the ability to readily produce a pressure measurement system. In one general aspect, a process for producing a pressure measurement system includes providing an assembly including a stem, a pressure detector, and a first circuit board. The pressure detector is operable to generate a signal based on pressure introduced through the stem, and the circuit board is operable to condition the signal. The process also includes compensating the assembly, determining a signal output type for a pressure measurement system that will include the assembly, and installing a second circuit board that produces the signal output type without materially affecting the compensation.Type: GrantFiled: August 27, 2004Date of Patent: August 7, 2007Assignee: Ashcroft-Nagano, Inc.Inventors: William Stephen Kosh, Yoshikazu Kaneko

Publication number: 20070068269Abstract: A system and method for pressure measurement may include the ability to readily produce a pressure measurement system. In one general aspect, pressure measurement may include a signal-converting circuit that includes a coupler, a signal biaser, and a signal span adjuster. The coupler is operable to receive a pressure-representative signal, and the signal biaser includes a thermally-insensitive voltage divider that facilitates biasing the pressure-representative signal. The signal span adjuster is coupled to the coupler and the signal biaser and includes a thermally-insensitive voltage divider that facilitates adjusting the span of the pressure-representative signal.Type: ApplicationFiled: September 1, 2006Publication date: March 29, 2007Inventors: David Lepine, Yoshikazu Kaneko

Patent number: 7150198Abstract: A pressure sensor (1) includes a diaphragm (21) with a bottom formed of a thin-wall portion (210) and a pressure introducing joint (10), in which an austenitic precipitation hardening Fe—Ni heat resisting steel having high mechanical strength is used for the diaphragm (21), while an austenitic stainless steel that is relatively inexpensive is used for the pressure introducing joint (10). The diaphragm (21) and the pressure introducing joint (10) are integrated by welding, and Ni content of a weld portion is appropriately adjusted. Thereby, the pressure sensor (1) achieves high accuracy and reliability, and usage amount of the expensive austenitic precipitation hardening Fe—Ni heat resisting steel can be minimized in manufacturing the pressure sensor (1). Also, since the austenitic stainless steel has an excellent corrosion resistance, the pressure sensor (1) can be used in measurement of a fluid with high corrosiveness.Type: GrantFiled: July 15, 2005Date of Patent: December 19, 2006Assignee: Nagano Keiki Co., Ltd.Inventors: Yoshikazu Kaneko, Hiroshi Wakabayashi, Takayuki Yokoyama
