Control Air | I/P Transducer | View PDF

A series of compact electronic pressure regulators that utilize unique control and feedback circuitry to provide precise, stable output. Immunity to the effects of vibration or mounting position, high tolerance to impure air, and low air consumption make this unit ideal for use in demanding applications.

Type 900X Miniature I/P, E/P Transducer for Electronic Air Pressure Control

Self -correcting to maintain precise control

The Type-9OOX l/P, E/P transducers are a series of compact electronic pressure regulators that convert an electrical signal (current or voltage) to a proportional pneumatic output. Utilizing internal solid-state feedback circuitry, the Type-9OOX provides precise, stable pressure outputs to final control elements. Immunity to the effects of vibration or mounting position, high tolerance to impure air, and low air consumption make this unit ideal for use in demanding applications.

The heart of this unique technology is a bimorph piezo actuator that is encapsulated in a protective skin. This protective skin provides defense against the humidity and contaminants often found in process operating environments.
