A pressure measuring unit includes a pressure measuring cell; a rotationally symmetrical sensor bushing into which the pressure measuring cell is inserted; a rotationally symmetrical process connection having, at one end, an inwardly extending encircling stop surface intended for the sensor bushing and, at another end, an opening for receiving the sensor bushing; a ring-like process seal between the sensor bushing and the stop surface of the process connection in order to thus prevent an ingress of the process medium into the pressure measuring unit; wherein the stop surface of the process connection and/or a counterpart stop surface, which in the installed state is directed toward the stop surface, of the sensor bushing have multiple individually formed webs configured such that the process seal is not extruded into the openings.

A field device adapter for wireless data transfer, comprises at least: an adapter housing; an adapter electronics unit arranged in the adapter housing, the adapter electronics unit comprising a first supply circuit, which is introduced into the first connection line, for providing a first supply voltage from a loop current flowing in the first connection line, and a second supply circuit, which is introduced into the second connection line, for providing a second supply voltage from the loop current flowing in the second connection line, wherein the adapter electronics unit further comprises a HART modem and a wireless module with an antenna for transmitting and/or receiving, and the adapter electronics unit is configured such that the first supply circuit supplies the HART modem with the first supply voltage, and the second supply circuit supplies the wireless module with the second supply voltage.

Field device adapter for wireless data transfer

A device for transferring signals using electromagnetic waves of a certain wavelength and based on a housing formed at least partially of metal for use in an explosion endangered area includes the housing; a transmitting/receiving unit for producing and/or receiving the electromagnetic waves; at least one primary antenna for out-coupling and/or in-coupling of the electromagnetic waves; at least one slot-shaped housing opening; and a formed part, which is made of a material having a dielectric number significantly greater than one and which extends to a predetermined maximum depth into the housing opening.

Disclosed is a field device adapter for HART communication with a field device. The field device adapter includes an adapter housing with an adapter chamber; arranged in the adapter chamber, an adapter electronics, which is adapted wirelessly to receive a second radio signal and by means of the second radio signal to control a circuit for shunting the communication resistor in such a manner that at least one communication resistor is selectively switchable in and out per radio, so that in a shunted condition a first radio signal received by the adapter electronics can be converted into a, preferably HART based, two conductor signal and modulated via the tapping point onto the loop current.
