A pressure transmitter includes a housing and a pressure sensor having an electrical characteristic that varies with applied pressure. The pressure sensor is configured to generate a sensor signal indicative of process fluid pressure. A transmitter isolation diaphragm is configured to couple to a process barrier seal to convey pressure to the pressure sensor. A flange is coupled to the transmitter isolation diaphragm. The flange includes at least one gas pathway extending inwardly from an outer diameter of the transmitter isolation diaphragm. Electronics are coupled to the pressure sensor to receive the sensor signal and to generate an output indicative of the pressure.

The differential pressure gauge includes a base, a first part disposed on an upper surface of the base, a second part disposed on the first part, and a diaphragm layer disposed between the first part and the second part. A wall is formed in a second pressure chamber formed in the second part between a first region on a side including a pressure-receiving portion and a second region on a side including a first through-hole, with a gap defined with respect to inner walls of the second pressure chamber.

A fuel assembly inspection system that utilizes a pressure transducer mounted to a utility's spent fuel handling tool to detect a relative change in depth of a fuel assembly during fuel inspections. The system then wirelessly transmits the signal to a fuel inspection recording system, which converts the signal to a relative height along the fuel assembly being viewed by a camera, and displays the relative height along with the applicable fuel assembly feature being viewed by the camera (e.g., nozzle, grid, span) via a text overlay on the video image of the inspection.

A mobile electronic device comprises a communication unit obtaining a first atmospheric pressure value from a roadside unit associated with a pedestrian bridge, an atmospheric pressure sensor obtaining a second atmospheric pressure value of the mobile electronic device, and a controller.

The disclosed technology includes an oil-filled pressure transducer assembly and an oil-filled compensating sensing element disposed near one another and attached to a common housing. The oil-filled pressure transducer assembly may receive and measure pressure media via a first oil-filled cavity and a protective diagram in communication with the pressure media.

In certain example implementations, the compensating sensing element is configured to measure certain common error phenomena that are also measured by the oil-filled pressure transducer assembly, for example, due to acceleration, temperature, and/or vibration. In certain implementations, the signal measured by the compensating sensing element may be subtracted from the signal measured by the oil-filled pressure transducer assembly to provide a compensated output signal.

Disclosed herein are advantageous measuring devices, and systems of the present disclosure and adjustment methods/techniques thereof. The present disclosure provides improved measuring devices (e.g., pressure/temperature measuring devices), and improved systems/methods for adjusting one or more features (e.g., offset and/or span) associated with measuring devices. More particularly, the present disclosure provides sealed measuring devices (e.g., sealed signal conditioning devices, such as sealed pressure transducers or transmitters) having adjustment members (e.g., magnet members) that allow a user to adjust the offset and/or span of the sealed measuring devices. The measuring devices include an adjustment member that allows a user to make adjustments to one or more features of the measuring devices. For example, a sealed pressure transducer can include an magnet member that allows a user to make fine (precision) adjustments of output offset and/or span (e.g., in the field), without breaching the enclosure or housing of the measuring device.
