ABSTRACT:
A transducer which provides a regulated pneumatic output as a function of an electric control input includes a housing, a gas regulator, and a particle trap. The housing has a passage therein, the passage including an inlet for receiving a pressurized gas supply and an outlet. The particle trap is disposed in the passage and includes a trap plate and a trap nozzle which directs gas against the trap plate so as to remove undesired entrained particles from the gas before it reaches the gas regulator.

Selected pages from a manual entitled "Product Manual for the Model 3311", bearing a date of Sep., 1991.
Eight (8) color photographs showing views of parts of a Model 3311 Current-to-Pressure Transducer. The parts are believed to be substantially the same as parts offered for sale by Rosemount Inc. prior to one year before the filing date of the present patent application, except that potions of some of the parts have been cut away to reveal details such as the placement of passageways. Connecting screws, and a gasket made to fit between the two main halves of the metal housing, are not shown in the photographs.
