Field device of measuring- and automation technology

A field device of measuring- and automation technology, comprising:

• a modular housing having at least a first housing module having at least a first housing chamber and a second housing module having at least a second housing chamber, wherein said first housing module is connectable with said second housing module via at least one pluggable connector coupling, wherein said at least one pluggable connector coupling has a first coupling element and a second coupling element;
• a sensor system for registering a measured variable dependent effect;
• an excitation unit for producing the measured variable dependent effect registrable by said sensor system;
• and
• an electronic operating circuit electrically coupled with said sensor system and with said excitation unit, wherein:
• said electronic operating circuit is arranged in said first housing module;
• said sensor system and said excitation unit are arranged at least partially in said second housing module;
• an electrical coupling of said excitation unit and said sensor system with said operating electronics is assured by said at least one pluggable connector coupling;
• said first coupling element and said second coupling element each have at least one contacting element for establishing an electrical coupling by bringing together said at least one contacting element of said first coupling element with said at least one contacting element of said second coupling element;
• a free volume remaining between said first coupling elements and said second coupling element after the bringing together of said first coupling element with said second coupling element is at least partially filled by a sealing element, said sealing element seals at least one pair of contacting elements for establishing an electrical connection completely from said remaining volume;
• wherein said excitation unit is a magnet system for producing a measuring tube vibration in a Coriolis flow measuring device;
• and said sensor system is a magnet system for registering a measuring tube vibration in a Coriolis flow measuring device;
• or
• wherein said excitation unit is a magnet system for producing an induced voltage in a medium in a magneto-inductive flow measuring device and wherein said sensor system is arranged for registering said induced voltage.
