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.

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 sensor assembly comprising a housing defining a cavity, and a pressure sensor package arranged within the cavity. The pressure sensor package includes a substrate having an aperture defined therethrough, a semiconductor die including a sensing diaphragm attached to the substrate such that the diaphragm is exposed via the aperture, and at least one electrically conductive element in electrical communication with the semiconductor die arranged on the substrate. A sealing element, such as an elastomeric o-ring, provides a seal between the housing and the substrate. A connector is secured to the housing via a crimped connection for establishing electrical connections between the pressure sensor package and an external system.

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.

A pressure gauge structure contains: a body having a bow-shaped frame and a holder mounted under the bow-shaped frame, and a contact film defined between the bow-shaped frame and the holder. A connector is connected on a bottom of the holder, and a test conduit passes through the holder and the connector and accommodates a tested object. The contact film contacts with a separation washer corresponding to the contact film.
