ABSTRACT:
A sheltered-type protection means for process instrumentation/automation, particularly quality measuring equipment for industrial processes with a hazardous environment and materials is described, which has a self-supporting housing with an extractable support member, on which is arranged at least one analyzer, a sample preparation means, an auxiliary material system and a unidirectional or bidirectional communications means for electrical signals. This arrangement permits a very compact construction and ensures that after extracting the support member unimpeded access to the individual components is possible. The invention also has the advantage that as a result of the small dimensions of the housing, it can be constructed in an extremely tight manner, so that the interior thereof is scavenged e.g. with an inert gas and can be kept under overpressure without leakage losses occurring. Thus, as the entire inner area is protected against explosions, there is no need to provide the individual components of the system in explosionproof and therefore expensive construction forms. The invention satisfies the requirement of being able to install the analyzer system in the immediate vicinity of the particular process and this covers both explosion protection and the necessary protection against the weather.
