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.
