Patent attributes
A measuring arrangement, including: a measuring transmitter with a sensor for registering a property of a medium and for issuing a primary signal dependent on the property; a transmitter housing, with at least one chamber and a first opening on the side facing the medium as well as a second opening, with a first contamination path section extending between the openings through the chamber; a first seal, which interrupts the first contamination path section; a circuit in the chamber, for processing the primary signal and producing an output signal, which is issued over a first signal path section through the second opening; a safety module, which includes: a module housing with at least one module chamber, having a first module opening on the side facing the transmitter and a second module opening, wherein a second contamination path section reaches from the first module opening at least as far as into the module chamber; at least a second seal, which interrupts the second contamination path section; and a second signal path section; wherein the safety module is connectable with the transmitter, such that the contamination path sections and signal path sections connect each to one another; and a leak detector, which monitors a contamination path section between the two seals.
