Model T5221 Adjustable Ratio E/P, I/P Pressure Transducer

Brand: Fairchild Industrial Products
When your application requires a very specific control system, look to the Rotork Fairchild T5221 Adjustable Ratio I/P, E/P Transducer.

The T5221 Transducer is an electro-pneumatic device that converts a DC current or voltage input signal to a proportional output pressure. This device is made up of four sections, the Signal Conversion Section, the Pneumatic Section, the Ratio Section, and the Booster Section.

The Fairchild T5221 I/P transducer has all the response and flow performance features of the T5200 series, with the addition of an Adjustable Gain from the ratio section, which allows this single device to cover most industrial and process control requirements.

The output pressure is a function of signal pressure times the ratio of lever arm lengths on either side of the Pivot.
Features
  • Shock and Vibration resistant
  • Temperature Compensation
  • Adjustable Positive and Negative Bias
  • High Output Flow
  • Adjustable Gain
