This disclosure provides example systems and methods for high pressure flat plate transducer assemblies. A first example embodiment of the transducer assembly is provided, which includes a transducer, a housing, and a transducer header. The transducer header can be configured for accepting the transducer and for mating with the housing at an interface between the header back side and the housing. The first embodiment of the transducer assembly is configured such that a pressure exerted on the transducer compresses the interface between the header back side and the housing. A second example embodiment is provided that includes a one-piece housing having a built-in header portion configured for accepting the transducer. In this second embodiment, the interface adapter is configured for attaching to a mating surface and to the housing. In the second example embodiment, the transducer assembly is configured such that the pressure presses the transducer against the housing.

Pressure measurement system (e.g., for an extracorporeal treatment system), method and pressure pod apparatus including a position sensor for use in repositioning a diaphragm that separates a liquid side cavity from a transducer side cavity (e.g., operatively connected to a pressure transducer); the liquid side cavity being in fluid communication with an inlet and an outlet.

A corrosion protection element is described, with which in simple and cost effective manner a reliable corrosion protection of field devices can be provided, which field devices comprise at least one component of stainless steel in contact with an environment of the field device. Corrosion protection elements of the invention are distinguished by features including that they are embodied as sacrificial anodes comprising iron or rustable steel and have a form, which is embodied in such a manner that they can be applied to the component of the field device in such a manner that the sacrificial anode is in electrically conducting contact with the component.

A pressure sensing device comprising a body assembly, a connector assembly, an electronic circuit, and a pressure sensor is provided. The pressure sensing device is a compact device allowing for improved assembly. Moreover, the pressure sensing device allows for a leakage test and an electronic circuit control test to be performed before the assembly of the device thereby improving reliability and precision.

A pressure sensor is described and shown for determining the pressure of a fluid medium in a volume limited by a wall. The pressure sensor includes at least one sensor element, a sensor housing, at least one first pressure compensation channel and a protective cap. The sensor element is arranged in the sensor housing. The protective cap is connected to the sensor housing on the medium side. The sensor element is connected to the medium via the at least one first pressure compensation channel during operation. The at least one first pressure compensation channel is at least partially introduced as a recess in the protective cap. The at least one first pressure compensation channel is geometrically designed in such a way that, in order to relieve the sensor element, pressure peaks are damped by deflection and/or by increased wall friction of the medium.

A differential pressure sensor includes a containment body including internally a wall creating first and second cavities, a piston slidingly housed in the first cavity and including a magnet mounted on a first axial end thereof, proximal to the wall and a magnetic sensor housed in the second cavity, near the wall for measuring the axial distance of the magnet from the wall and generating a signal representing such distance. The pressure sensor further includes a lighting element for emitting light radiation, a control circuit operatively interposed between the magnetic sensor and the lighting element and configured for varying the light radiation emitted by the lighting element as a function of a variation in the representative signal generated by the magnetic sensor. An interface element includes a radiant surface facing outwards from the body and an optical guide, extending between the lighting element and the radiant surface.

A modular field device kit with interchangeable components allowing for customization and a method of assembly of a field device using such kit.

A protective housing for protecting an electronic device includes a plurality of walls defining a casing, a plurality of partitions, and at least one flow groove. One of the walls of the housing, referred to as the main wall, has an opening covered with a membrane for exposing a part of a measuring device to atmospheric pressure. The plurality of partitions are arranged on the outer surface of the main wall and separated from each other by passages. The plurality of partitions are arranged around the opening to completely surround the opening and protect the membrane. The at least one flow groove is arranged next to the opening, in order to allow liquid that may accumulate around the opening and/or against the partitions to be discharged. The present disclosure also concerns a pressure sensor, in particular, for a tank of a motor vehicle, using such a protective housing.

A physical quantity measuring device includes: a metallic cylindrical case; a sensor module configured to detect a physical quantity; a synthetic-resin joint provided near a first open end of the cylindrical case, the joint being attached with the sensor module and provided with an introduction port for introducing a measurement target fluid; and a cover provided near a second open end of the cylindrical case. The cover includes a locking portion for locking the sensor module. The cylindrical case includes an engagement portion provided near the first open end and engaged with the joint and a crimp portion provided near the second open end, the crimp portion configured to be plastically deformed by crimping. The cover is attached to the cylindrical case by crimping the crimp portion.

A protective housing for protecting an electronic device includes a housing having walls. One of the walls of the housing, referred to as the main wall, has an opening for exposing a part of a measuring device to atmospheric pressure. The housing comprises, arranged on the outer surface of the main wall, a plurality of partitions separated from each other by passages and arranged around the opening to completely surround it and at least one flow groove arranged next to the opening, in order to allow liquid that may be likely to accumulate around the opening and/or against the partitions to be discharged. The present disclosure also concerns a pressure sensor, in particular, for a tank of a motor vehicle, using such a protective housing.
