A sensor and insertion assembly 2 is used for intravascular measurement of pressure in a living body. The assembly includes, a sensor chip 6 having a substrate body 8 with a recess covered by a pressure sensitive film 10 thereby forming a cavity 12. A piezoelectric element, preferably in the form of a piezoelectric film 14, is arranged in connection with the pressure sensitive film, and energy is applied to the piezoelectric element such that acoustic waves are generated in the element. The piez...

The invention provides a pressure sensor with a housing for a pressure sensing arrangement, e.g. a semi-conductor arrangement. The housing consists of a bottom part and an intermediate member with a through hole forming a sidewall of a cavity for the pressure sensing arrangement. A membrane is attached to the intermediate member to cover an opening of the cavity, and to allow pressure from outside to propagate into a pressure transmitting medium contained inside the housing and thus to the press...

A pressure tank includes a liner separated into a cap and a main body. A shell covers the outer surface of the liner. The shell is formed of a fiber reinforced plastic. A heat exchanger is arranged in the liner. A header is connected to the heat exchanger. The heat exchanger is supported on the liner by fastening the header to the cap or the main body.

The invention relates to a pressure transmitter for an overload-proof pressure gauge, comprising a base body, a separating membrane disposed on a pressure-sensitive side of the pressure transmitter and subjectable to a pressure to be measured, a communicating chamber located inside said base body, which receives a pressure transmission medium, said chamber being closed on the pressure-sensitive side by the separating membrane, wherein the coefficient of thermal expansion of the pressure transmis...

To accurately set a detection axis of a sensor even when the sensor is attached to an inclined surface, provided is: a sensor responsive to an operation to a predetermined detection axis. A sensor device accommodates this sensor 1 and is a lead provided for conduction between a terminal of this sensor device and a mounting board. A mold for fixing the sensor device to set the detection axis of the sensor and a bottom surface of the mold with a desired angle is also provided.

In a pressure sensor which has a metal housing 12 containing a sensor chip 11 and a joint housing 14 and in which an insulating member 15 is arranged to electrically insulate both of the metal housing 12 and the joint housing 14 from each other, the metal housing 12 is connected to a stable potential such as, for example, a sensor power supply or a sensor ground. Thus, there can be solved a problem that the detection signal is liable to be influenced by electric noise from outside where a signal...

The invention relates to a pressure module for locking a female connector in a connecting socket, comprising a guide body, a spring and a cable fixing element, with the spring being able to act on the cable fixing element.

A lower capacitive electrode and a capacitive electrode of an opposite substrate are provided to mutually facing surfaces of a TFT substrate and the opposite substrate, respectively; and a seal member is provided to the peripheral part of both substrates. The seal member creates a predetermined gap between the substrates, and the surrounded space is sealed by the seal member. A pressure sensor measures pressure applied to the substrates based on variations in capacitance between the lower capaci...

A pressure sensor has a case having a first side and a second side, and a sensing portion mounted to the case. A first diaphragm is disposed on the first side of the case such that a first chamber is defined. A second diaphragm is disposed on the second side of the case such that a second chamber is defined. The first chamber and the second chamber are filled with a pressure medium such as an oil. The case forms an introduction passage for introducing the pressure medium into the first chamber a...
