The Series 2700 Current to Pressure Transducer combines economical startup cost, low air consumption, and reliable performance to make the 2700 a great investment. The unit converts a variable current signal to a proportional pneumatic output. It has input and output ports on both the front and back which allows for versatile plumbing. The NEMA 4X enclosure enables the unit to be installed indoors or outdoors, however, the unit is not vibration resistant. It is FM and CSA approved for intrinsically safe operation. The 2700 is designed for remote or panel mounting. An integral volume

booster provides high ow capacity, increasing control speed in critical applications.

Other features include external zero and span adjustments which are convenient for

eld calibration.

The Series 2800 Current to Pressure Transducer 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 eld 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 eld reversible.

Transducers

It is FM and CSA approved intrinsically safe, as well. For ease of installation, this

Current to Pressure

model has input and output ports on both the front and back and can be easily panel mounted.
