The invention relates to an assembly for use in automation and process measurement technology, comprising an at least two-part compact housing having a sleeve-shaped housing bottom part and housing top part. According to the invention the housing top part and the housing bottom part are each made integrally from a creep-resistant material and have an overlapping region extending in an axial direction, wherein the cross-sectional shape of the housing top part and the housing bottom part is complementary at least in the overlapping region and the housing parts have an oversize relative to one another. The housing top and bottom parts are connected to each other by axial pressing forces with oversize loss in a media-tight manner.

Two-part housing for receiving electronic components and process connection means for use in process measurement technology

A flow sensor for flowing media with a cylindrical housing () and with a sensor element located in the housing (), the housing () preferably having an outside thread () and being screwable into a union () of a pipe () or into an opening of a connecting piece (). The flow sensor () has very high measurement accuracy while still being economically producible. There is a lifting body () which projects into the flowing medium, the lifting body () being movably guided on the housing () and depending on the flow () of the medium to be monitored, can be moved against the reset force of a reset element which is located between the housing () and the lifting body (), and the sensor element is made as a noncontact proximity switch () which produces a signal that is dependent on the position of the lifting body ().

Flow sensor

A heat transfer monitoring and/or measuring device, especially a flow indicator for media flowing through a pipe ( ), tank or fitting, with a sensor housing ( ) and with two sensor elements ( ), the sensor elements ( ) each having a metallic sensor surface ( ) which comes into contact with the flowing medium. In the flow indicator, the problem &ldquo;deposition or formation&rdquo; of disruptive layers on the sensor surfaces ( ) of the sensor elements ( ) is solved by the element ( ) which is made as a heating element having an electrically conductive protective lead ( ) and by the protective lead ( ) forming a closed protective circuit which includes the pipe ( ), tank, or the fitting, the flowing medium and the sensor element ( ).

Heat transfer monitoring/measuring device

Heat transmission monitoring and/or measuring apparatus

A process for monitoring the flow of flowing media, especially for acquiring the heat transport capacity of the flowing medium, in which a measurement signal of a temperature measurement element influenced by at least one heating element and the medium flowing past it is monitored and in which an output signal is generated when the measurement signal of the temperature measurement element exceeds or falls below a switching point. A reduction of the reaction time of the process for monitoring the flow of flowing media is guaranteed by the heat output of the heating element and/or the location of the switching point changing as a function of the output signal.
