Series 2800 Current to Pressure Transducer

Specifications - Installation and Operating Instructions

Bulletin V-4

The Series 2800 Current to Pressure Transducer converts a current

input to a linearly proportional pneumatic output pressure. This unit

utilizes a closed loop pressure feedback system that closely controls

output and compensates for vibration, mounting angle, temperature, and

supply pressure variations. These characteristics make this unit ideal for

field mounting on a valve. The control mechanism is a piezoceramic

actuator encapsulated in a protective skin, which provides a constant

defense against humidity and contaminants. These features make this

unit ideal for use in demanding applications. The 2800 also comes in a

NEMA 4X enclosure and is field reversible. It is FM and CSA approved

intrinsically safe, as well. For ease of installation, this model has input

and output ports on both the front and back and can be easily panel

mounted.
