A remote seal system includes a remote diaphragm having a first side configured to be exposed to a process fluid. A conduit is coupled to the remote diaphragm and includes a fill fluid in fluidic communication with a second side of the remote diaphragm. A temperature sensor is thermally coupled to the conduit and configured to sense a temperature of the fill fluid. In one alternative example, a remote sensing assembly includes a flexible elongate conduit having a first end coupled to a remote diaphragm in fluidic communication with a process fluid and a second end extending a length from the first end to a process fluid pressure transmitter. A substantially incompressible fill fluid is disposed within the flexible elongate conduit. The process fluid pressure transmitter is configured to generate an output value indicative of pressure in the process fluid based on a corresponding pressure in the fill fluid. A temperature detector is coupled to the flexible elongate conduit and is configured to provide a signal indicative of an average temperature of the fill fluid along the flexible elongate conduit. A compensation system calculates a thermal expansion value based on the average temperature and adjusts the pressure signal based on the thermal expansion value.

A pressure gauge flange assembly for connection to pressure equipment and a pressure gauge. The pressure gauge flange assembly has a flange housing with a flange at a lower portion that connects to pressure equipment such as a BOP. Within the flange housing a chamber is provided that is separated into two chambers by a piston. The piston is moveable to balance pressure in the two chambers. Fluid from the pressure equipment may be dirty. On the other side of the piston, clean fluid is provided so that any dirty hydraulic fluid from the pressure equipment does not impair operation of the pressure gauge.

A single-use adapter for coupling a single-use container to a reusable sensor transducer includes an attachment region. The single-use adapter includes a deflectable diaphragm sealingly coupling to the attachment region and configured to contact a media sample. The single-use adapter also includes a radio-frequency identification (RFID) tag coupled to the single-use adapter and configured to store and transmit data.

An in-cylinder pressure sensor system and a pressure sensor adaptor that allows for the inclusion of a pressure sensor to monitor the pressure of an engine cylinder is provided. The pressure sensor adaptor includes a first end, a second end, a threaded section, a cylindrical midsection, and an annular section; and a pressure sensor channel that comprises an opening in the first end and an opening in a second end and spans from the first end to the second end through the threaded section, the cylindrical midsection, and the annular section. The pressure sensor may be housed in the pressure sensor channel of the pressure sensor adaptor.

An apparatus includes a base assembly, a gasket and a housing assembly. The base assembly may have a locking feature and a bearing feature. The locking feature may have a first passage in communication with an exterior of the apparatus. The gasket may be disposed on the base assembly and may have (i) a base portion, (ii) a column portion and (iii) a second passage in communication with the first passage. The housing assembly may have a sealing feature and may be configured to hold a sensor. The sealing feature (a) may mate with the bearing feature and (b) may compress the base portion of the gasket. The sensor (a) may seal to the column portion of the gasket and (b) may be in communication with the exterior of the apparatus through the first passage and the second passage.

The present disclosure discloses process seals having a form retaining core and a coating of a thermoplastic sealing material for pressure sensors. The process seals can be replaced in simple manner, especially essentially without loss of measurement accuracy. The process seals are characterized by features including that they are pre-aged in a pre-aging method performable in a reproducible manner and insertable in the pressure sensor as replaceable components, wherein the process seals were clamped during the pre-aging method in a clamping apparatus exerting a clamping force thereon, wherein the clamping apparatus has a clamping geometry surrounding the process seal clamped therein, which is essentially identical to the clamping geometry surrounding the process seal in the pressure sensor.

The invention refers to a pressure-measuring device for converting a mechanical or hydraulic pressurization in a measuring signal and for forwarding the measuring signal to a remote evaluation unit. The invention distinguishes by a fastening device (1) for fastening the pressure-measuring device to a machine housing of a motor or a pump, a transmitter head (4) which is arranged on a measuring device head (3) of the pressure measuring device and which is to be connected to a light source via a first optical fiber (25), a receiver head (5) which is arranged on the measuring device head (3) of the pressure measuring device and which is arranged opposite to the transmitter head (4) to receive the light emitted by the transmitter head (4) via a light path in the measuring device head (3) and to be connected to the evaluation unit via a second optical fiber (26), and a measuring element (14), which in case of a mechanical or hydraulic pressure is displaceable on the measuring device head (3) into the light path between the transmitter head (4) and the receiver head (5).

Various embodiments described herein relate to apparatuses and methods associated with fluid pressure sensor systems and sealing members for the same. The sensing apparatus can include a sensor disposed on a substrate and an engagement member including a generally columnar sealing member configured to engage an inner cylindrical surface of a receiving tube within the housing connected to the substrate about the sensor. The sealing member can define an axial bore extending from a proximal end to a distal end, and one or more media can be disposed in the axial bore such that the sensor can detect a force applied to the media. The sealing member can include an outer sealing surface defining one or more engaging elements extending circumferentially about the sealing member, the one or more engaging elements configured to non-adhesively engage the inner cylindrical surface of the receiving tube to resist removal of the sensor assembly.

A pressure gauge broadly comprising a conduit, a pressure indicator, and a tip assembly. The tip assembly extends from the distal end of the conduit and includes an inner shaft, an annular seat, and an outer tip. The inner shaft engages a valve stem core of a valve. The annular seat cradles and provides support to the outer tip. The outer tip forms a seal against a valve stem tube of the valve and has an outer surface having a semi-spherical, dome, or frusto-conical shape for ensuring that the seal is formed regardless of the angle at which the tip engages the valve.

The present invention relates to a component for measuring a pressure change in a pouch-type battery, and a method for measuring a pressure change in a pouch-type battery by using the same and, particularly, to: a component connectable to pressure gauge by being mounted in a pouch-type battery for measuring a pressure change in the pouch-type battery; and a method for measuring a pressure change in a pouch-type battery by using the same.
