• High Precision I/P Pressure Transducers (TXI7800)

  
  Designed for use in hazardous environments, the Fairchild TXI7800 series product is an explosion proof I/P pressure transducer. It operates under the same principles as the T7800 product; however the TXI series includes NEMA 4X explosion proof construction. Our design isolates the electronics chamber from the pneumatic section, thereby creating a safer and longer service life product, especially for applications handling natural gas. In the Extended Range units, the TXI7800 series will also deliver up to 0-120 psi [0-8.0 BAR], (0-800 kPa) output. The TXI7800 series is approved for hazardous use and carries FM. CSA, ATEX and IECEx approvals.

• Moisture Resistant I/P Pressure Transducers (TXI7850)

  
  Fairchild's TXI7850 I/P Pressure Transducer operates under the same basic principles as the TXI7800, yet improves upon the design. By encapsulating and otherwise protecting the critical components, Fairchild designed the Explosion proof TXI7850 I/P Pressure Transducer to be highly resistant to moisture within the supply air lines. Available in both standard and extended range configurations, the TXI7850 delivers vibration, shock and moisture resistance in output pressures up to 0-120 psi [0-8.0 BAR], (0-800 kPa). It carries full Agency Approvals, including FM, CSA and ATEX certifications.

• Compact E/P, I/P Low Pressure Transducers (T7500)

  

  The T7500 series low pressure transducer converts DC electronic input signal to a proportional low pressure pneumatic output. The transducer employs electronic closed loop feedback in conjunction with a piezoceramic actuator flapper nozzle system in the pilot stage to control the signal pressure of an integral pneumatic volume booster. The volume booster employs a highly sensitive control diaphragm and main valve to accurately control the flow of air to the downstream system in response to the pressure received from the pilot stage. The electronic closed loop feedback senses the output pressure of the volume booster directly to affect the ultimate in accurate pressure control.

• 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.

• Electro-Pneumatic Pressure Controller (T9000)

  
  The Fairchild T9000 Series Electro-Pneumatic Pressure Controller has a closed-loop, integrated, microprocessor control system that regulates outlet pressure. The Model T9000 controls pressure in proportion to an analog electrical input signal. An internal feedback sensor monitors output pressure to achieve high accuracy. You can control the output from the Model T9000 using the keypad or from an analog control signal. You can control the output from the Model T9000D using the keypad and through DeviceNet™ Communication network. With its integral booster sections, the T9000 series of I/P pressure controllers delivers high accuracy at flow capacities of 1 SCFM in the T9000, 90 SCFM in the T9020, 110 SCFM in the T9040, 220 SCFM in the T9060, and 700 SCFM in the T9080.

• Fast Response E/P, I/P Pressure Transducers (T5200)

  
  Rotork Fairchild's T5200 Transducer is a Fast Response I/P, E/P Transducer controlled by a 4-20 mA current in a control loop. With its reliable signal conversion and pneumatic circuit sections, the T5200 I/P Transducer provides fast response to input signal changes, resulting in faster loop control and savings in process materials. The Signal Conversion Section (PC Board) accepts a 4-20 mA current from the control loop. This signal current 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 of the Flexure Arm. Its minimal air consumption allows you to use the T5200 in systems where operating gas is expensive. Five available input signal ranges deliver the versatility to meet most process and machine requirements. These available inputs are 1-5 mA, 4-20 mA, 10-50 mA, 1-5 VDC and 1-9 VDC, each with the corresponding output range of 3-15 psig, [0.2-1.0 BAR], (20-100 kPa).

• 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.
