Embodiment Construction
[0017] The drawing shows a section through a process transmitter 1 in a housing. The housing is divided into two chambers 2,3. The first chamber 2 is called electronics compartment and the second chamber 3 is called connector space. In the first chamber 2 are only electronic components such as input / output units 4 , 5 , fieldbus 6 and power supply 7 . Arranged below these electronic components 4 , 5 , 6 , 7 is a measuring unit 8 .
[0018] Arranged in the second chamber 3 is a support element in the form of a circuit board 9 on which are positioned various connection elements 10, 11 for accommodating external cables and, moreover, a service interface 14 in the form of an RJ45 interface and a display and keyboard15. A plurality of microswitches 16 and LEDs 12 are also present on the circuit board 9 . Likewise, switching logic 18 is located on circuit board 9 in the form of a microprocessor. Since switching logic 18 only forwards digital signals, it requires only a small am...

Abstract
The invention relates to an electronic device comprising a housing for receiving electronic components, preferably a process transmitter, wherein the housing has two chambers (2, 3) in which electronic components (4, 5, 6, 7, 8) and user interfaces (14,15) and / or connecting elements (10, 11, 12, 13) for cables are arranged, the electronic components (4, 5, 6, 7) being arranged in a first chamber (2). In order to provide a process transmitter which is easily maintained, electronic components (4, 5, 6, 7, 8) are arranged exclusively in the first chamber (2) while the user interfaces (14, 15) of the electronic components (4, 5, 6, 7, 8) and / or connecting elements (10, 11, 12, 13) for cables are positioned exclusively in the second chamber (2).
Description
technical field [0001] The invention relates to an electronic device with a housing for accommodating electronic components, preferably forming electronic components of a process transmitter, wherein the housing comprises two chambers in which the electronic components and A user interface and / or a connection element for a cable, wherein the electronic component is arranged in the first chamber. Background technique [0002] Process transmitters, which are used, for example, in process control technology, especially in the chemical industry, comprise various electronic components, for example, modules such as fieldbuses, measuring units or analogue electrical signal inputs and outputs, as well as power supplies. In order to be able to program or maintain these electronic components for the respective application, a user interface is provided. These electronic parts are connected with external devices through connection terminals. In this case, the housing of the process tr...
