• P/I Pressure Transducer (T8000)

  Our T8000 P/I Transducer Series is a miniature two wire pressure device that converts a pneumatic input signal to a linearly proportional output current. It is field reversible and offers output choices of 4-20 mA or 10-50 mA. The T8000 Series is designed for precision applications providing maximum versatility. The modular construction permits any basic unit to be used in the explosion-proof, rack, wall, pipe, panel, DIN rail or 3, 5, 10, or 15 unit manifold configurations. Servicing or calibration is quick and easy. The Zero and Span adjustments are easily accessible from the front of the unit. The T8000 Series may be configured as a Single or Dual Channel Unit. The Dual Channel Unit consists of two PC Boards that are enclosed within the same housing and function independently of each other. This unit may be offered in any one of the seven standard input pressure signals or in any combination.

• Adjustable Ratio, E/P, I/P Pressure Transducer (T5221)

  When your application requires a very specific control system, look to the 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.

• Rack Kits for T6000, T7800 and T8000 Transducers

  All T6000, T7800 and T8000 Rack Kits utilize a 10 unit manifold described in the above manifold kits. The rack kit includes additional hardware to permit installation in a standard 19" Rack. It is suggested that transducers used with rack kits include the "R" option. This option faces the electrical terminal block connector to the rear of the transducer permitting connections to the transducer to be made from the rear of the rack.

• High Flow E/P, I/P Pressure Transducers (T5700)

  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 (.05 SCFM) dramatically reduces air consumption.

• Fast Response High Flow E/P, I/P Pressure Transducers (T5220)

  As a Fast Response High Flow I/P, E/P Transducer, the Fairchild T5220 has all the performance you want in a voice coil I/P transducer product, but it also includes a built in booster section to deliver high flow capacity, up to 45 SCFM (76.5 m3/HR) with six available rations to allow pressure multiplication to the output. This feature, along with the adjustable positive and negative bias allows you to custom design your control system for exactly the desired performance. The Signal Conversion Section (PC Board) accepts a DC current or voltage. This signal is applied to a coil which creates a magnetic force that moves a Flexure Arm. The Pneumatic Section operates as a force balance system. A Sapphire Ball floats inside a Nozzle and controls the output pressure by exhausting air supplied through an Orifice. This Sapphire Ball acts as a piston exerting a force which is balanced against the force transferred to the Flexure Arm by the Coil. The Booster Section amplifies the output pressure of the transducer.

• Lock in Place I/P Pressure Transducers (T6100)

  Uniquely designed by Fairchild, the T6100 "Lock in Last Place" I/P pressure transducer provides flexibility, reliability and safety in applications requiring protection from signal failures to critical control system instruments. Its simple yet effective voice coil actuation now Locks in "Last Position" to accurately capture the setpoint with extremely low drift after a power loss permits the T6100 to maintain set point. The unit's IP65 rating allows you to handle moist applications with ease. Design of the T6100 relies on a proprietary integrated solenoid valve module interposed between the flapper-nozzle pilot and the booster section. Upon signal failure, an electrical charge stored within the active electronic circuit controlling the integrated solenoid valve module maintains the current to the voice coil at its last setpoint. Simultaneously, a high energy pulse closes the solenoid valve, trapping the signal pressure within the signal chamber at the last setpoint. The booster continues to provide its normal forward and exhaust flow, with the constant signal pressure now captured and maintained within the signal chamber. Advanced valve orifice design of the T6100 increases its forward flow capacity to a minimum of 5-scfm at 21-psig supply pressure.
