A fluid monitoring assembly includes a conduit having a wall defining a lumen for carrying fluid. A sensor mount is integrally formed with the wall of the conduit and extends generally transverse with respect to a longitudinal axis of the conduit, the sensor mount including an aperture defining an inner surface extending to the lumen. The assembly includes a sensor configured to be removably secured within the sensor mount, the sensor having an elongate body terminating at one end thereof in a sensing portion, the elongate body having a male projection on a portion thereof and configured to rest within the inner surface of the sensor mount. The assembly further includes a housing having first and second portions connected to one another, the housing defining an interior portion configured to encapsulate the conduit, at least a portion of the elongate body of the sensor, and the sensor mount.

Systems and methods for sensing pressure, and protecting a sensor within a sensor assembly. A sensor assembly may comprise a sensor having at least one pressure input port; a first housing configured to encapsulate the sensor; a second housing configured to attach to the first housing to encapsulate the sensor; a first O-ring located between the first housing and the sensor; a second O-ring located between the second housing and the sensor; and a printed circuit board configured to receive detected pressure information from the sensor.

A measuring transducer for metrological registering of a pressure to be measured as relative pressure referenced to a reference pressure reigning in the environment of the measuring transducer, comprising: a housing; a relative pressure sensor arranged in the housing; a pressure supply, via which the pressure to be measured is fed to the relative pressure sensor, and a reference pressure supply, via which the reference pressure is fed to the relative pressure sensor. An entrance of and to the reference pressure supply communicates with an opening in a housing outer wall, on whose exterior the reference pressure acts, characterized in that a pressure equalizing element is applied in the entrance of the reference pressure supply, and the pressure equalizing element has a securement element, a filter element and a protective cap.

A drying module for a relative pressure measuring transducer, which has in the interior of a housing of the measuring transducer a reference pressure supply leading from a relative pressure sensor to an opening in a housing wall of the housing, and which has a connection element, whose inner space is connected via the opening with the reference pressure supply extending in the measuring transducer. The drying module comprises a module housing, which has an inner space, in which a drying means is located, and, extending through the module housing (23), a reference pressure supply, whose first end is contactable with the reference pressure via an opening of the module housing, whose second end is connectable to the reference pressure supply of the measuring transducer via a connection element of the drying module connectable with the connection element of the measuring transducer, and whose inner space in the module housing is in humidity permeable connection with the inner space containing the drying means.

A measuring rake, configured to be arranged on a link rod, includes a sheath including a front face and two side walls delimiting between them a recess configured to receive the link rod, an electronic circuit arranged on the front face of the sheath and including at least one sensor, a patched leading edge fixed removably to the sheath, and a seal arranged between the patched leading edge and the electronic circuit, the patched leading edge including a plurality of air intakes, each forming a fluidic passage between an outer face and an inner face of the patched leading edge opening out facing at least one sensor of the electronic circuit, the measuring rake making it possible to obtain a measuring tool which can be assembled simply and quickly, with easy access to the electronic circuit, and making it possible to avoid problems of orifice blockages or air leaks.

A pressure sensor module for a process pressure transmitter is provided. The pressure sensor module includes a first member formed of a metal suitable for exposure to seawater. The first member has a passageway extending therethrough. An isolation diaphragm is coupled to the first member and has a first side configured to contact a process fluid and an opposite side in fluidic communication with the passageway of the first member. A second member is formed of a different metal than the first member and is mechanically coupled to the first member to define a chamber that is fluidically coupled to the passageway. A pressure sensor is disposed to sense a pressure within the chamber. A seal is coupled to the first and second members to seal an interface between the first and second members.

A physical quantity measuring device includes: a sensor module provided with a diaphragm; a joint to which the sensor module is attached, the joint including a pressure inlet for delivering fluid to be measured to the sensor module. The joint is made of a synthetic resin and includes a joint body and an elastically deformable claw provided to the joint body and configured to lock the sensor module. Since the claw keeps the sensor module to be held by virtue of the elastic force of the claw, a further attachment process such as welding for attaching the sensor module to the joint is unnecessary. Since the joint body and the claw are integrally made of synthetic resin, it is not necessary to separately manufacture the joint body and the claw.

A pressure indicator: a body having a pressure chamber which has an inlet for communication with a fluid; a resilient diaphragm having a periphery sealed against the body and having one side thereof exposed to the fluid within the chamber; an indicating arm having an inner end which is integrally formed with the other side of the diaphragm and an outer end arm which is adjacent to a scale, the arrangement being such that pressure of the fluid within the chamber causes resilient deformation of the diaphragm which in turn causes the outer end of the arm to move relative to the scale thereby indicating the pressure of the fluid in the chamber.

In an oil-pressure-sensor attachment structure according to an aspect of the invention, an oil channel body includes a lower body and an upper body arranged at an upper side of the lower body in a superposed manner. The attachment structure includes the upper body, a sensor case, and a connection member including an electrical connection portion that electrically connects an external power supply with a sensor main body. The connection member contacts the upper body from the upper side. The upper body has a through hole in an up-down direction. The sensor case includes a columnar portion that extends in the up-down direction and is inserted into the through hole, a flange portion that protrudes outward in the radial direction from the columnar portion and is arranged to face the lower side of the upper body, and a first hook portion that is hooked to the connection member.

The invention relates to a sensor device particularly for maritime applications, comprising a housing (1) that has a pressure connection (7) leading to a pressure sensor (9) that transmits measurement data using a transmission device (17, 19), and at least one closeable passage opening (31) for connecting the surroundings to at least parts (33) of the housing interior in which the pressure sensor (9) is arranged, characterised in that said pressure sensor (9) is surrounded by an incompressible medium that is separated from the surroundings by an elastically-yielding, media-tight separating arrangement (49).
