Provided is a pressure detection device that can suppress variation in the pressure detection characteristics of a pressure detection unit from occurring due to individual differences in the shape of flow passage units, variation in work in mounting the flow passage unit on the pressure detection unit, or the like. The pressure detection device including: a pressure detection unit; a flow passage unit; and a mounting unit configured to removably mount the flow passage unit on the pressure detection unit. The pressure detection unit has a pressure detecting diaphragm and a sensor rod arranged at the center part of a first surface of the pressure detecting diaphragm. The flow passage unit has a flow passage diaphragm, and a displacement of the flow passage diaphragm in contact with the top surface is transmitted to the pressure detecting diaphragm via the sensor rod.

A method for preserving wine or other oxygen sensitive items is disclosed. In some embodiments, the method involves injecting 0.15 gram to 0.5 gram of an inert gas into a container comprising wine and oxygen, without raising a pressure within the container above 10 psig, to form a barrier layer of the inert gas between the wine and the oxygen in the container without displacing all of the oxygen from the container.

An overpressure indicator is defined by a housing sized and configured for attachment within a compartment interior, such as an aircraft nacelle. A pressure sensing element disposed within the housing is coupled to an indicator element and is configured to detect a pressure differential between the interior and exterior of the compartment. The indicator element is caused to move in response to a predetermined change in pressure exceeding a threshold pressure differential. The indicator element includes a distal end that is moved to a position exterior of the housing and the compartment, providing a visual indication of an overpressure condition. A reset feature provided on the indicator can only be accessed by first opening the compartment in which the indicator has been mounted. A spring can be provided to assist in the triggering of the indicator member after the threshold pressure differential has been detected.

A method of preserving an oxygen sensitive item is disclosed. The method involves injecting at least 0.15 gram of an inert gas into a container comprising the oxygen sensitive item and oxygen, without raising a pressure within the container above 10 psig, to form a barrier layer of the inert gas between the oxygen sensitive item and the oxygen in the container without displacing all of the oxygen from the container.

A gauge for a hybrid pressure and flowgauge regulator includes first indicia and second indicia. The first indicia provides an indication of a flow rate of a gas exiting an outlet of the hybrid pressure and flowgauge regulator when the gas exits with a pressure below a gauge threshold pressure. The second indicia provides an indication of the pressure of the gas exiting the outlet of the hybrid pressure and flowgauge regulator when the pressure of the gas exiting the outlet is above the gauge threshold pressure.

An infusion arrangement for administering a medical fluid includes a pump apparatus with an elastomeric membrane which forms a pump volume. The elastomeric membrane is elastically extended in a fill state, filled at least partially with medical fluid, of the pump volume and produces a delivery pressure on the pump volume. An infusion line is connected to the pump volume and provided with a patient access for fluid-conducting connection. A main fluid channel transfers medical fluid from the pump volume to the patient access. A monitoring device is connected to the infusion line and configured for monitoring the pump apparatus. The monitoring device has a differential pressure-measuring element connected to the main fluid channel and designed such that differential pressure formed along a channel portion of the main fluid channel can be detected by the differential pressure-measuring element and a delivery rate of the medical fluid can be indicated.

A measuring system for detecting pressure and/or density, having at least one process connector, a diaphragm, a measuring unit, a housing and a display, wherein a process pressure acts via the process connector on the diaphragm and the measuring unit converts a stroke of the diaphragm caused thereby into a rotational movement of a pointer when the process pressure is changed via the measuring unit, and the pointer on the display shows the pressure applied on the diaphragm on a scale. The measuring system includes a connecting piece which includes the process connector, a meter base and a tubular extension.

A method and device for preserving wine or other oxygen sensitive items is disclosed. In some embodiments, the method involves injecting at least 0.15 gram of an inert gas to a closed container comprising wine and oxygen. In some embodiments, the device has a housing, a pressure indicator, a pressure sensor, and a one-way valve. The housing is configured to seal an opening of a wine bottle. The housing has a closure side configured to be in communication with an interior of the wine bottle. The housing has an input channel extending through the housing. The pressure sensor is within the housing and is in communication with the closure side. The one-way valve is in the input channel. The pressure sensor is configured to move the pressure indicator to an indicating position when a predetermined amount of pressure is reached at the sensor.

An electronic device includes a package substrate, a circuit assembly, and a housing. The circuit assembly is mounted on the package substrate. The circuit assembly includes a first sealed cavity formed in a device substrate. The housing is mounted on the package substrate to form a second sealed cavity about the circuit assembly.
