Model T5700 High Flow E/P, I/P Pressure Transducer

Brand: Fairchild Industrial Products
Rotork Fairchild's Model T5700 is an electro-pneumatic transducer that converts a current signal to a linear pneumatic output, using a force balance system with a flapper and the nozzle to control the pressure in the intermediate housing.

Its low droop under flow conditions allows improved control of downstream pressure. Additionally, the T5700 has high flow and is virtually immune to supply pressure change, which permits use of normal plant air.

The T5700's minimal air use in dead end service (0.05 SCFM) dramatically reduces air consumption.
Features
  • Low Droop under flow conditions
  • Immune to Supply Pressure Change
  • Minimal Air Use in dead end service (0.05 SCFM)
  • High Forward and Exhaust Capacity
  • Output may be directly or inversely proportional to the input
  • Split Range Operation
  • Built in Supply Pressure Regulator
  • Wall or Panel Mounting
