Dwyer 2800 - Manual

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. SPECIFICATIONS
