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.

Compact E/P, I/P Low Pressure Transducers (T7500)
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.
Compact E/P, I/P Pressure Transducers (T6000)The T6000 compact size E/P, I/P pressure transducer is a field reversible unit that provides an output directly or inversely proportional to the input signal. Its six available output pressure ranges and six available input signal ranges meet most process and machine requirements. The T6000 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 and servicing or calibration is quick and easy. An extended range T6000 I/P Transducer is also available, which provides output pressure capability up to 0-120 psi [0-8.0 BAR], (0-800 kPa). The Extended Unit is made up of three sections, the Primary Control Section, the Pneumatic Relay Section, and an additional Pneumatic Relay Section. The additional Relay Section is used to amplify the output pressure.
Explosion Proof 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.
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).
PAX1 Electric Linear ActuatorRotork Fairchild's all new PAX1 Series Linear Actuator can be used alone or it can be paired with a variety of Fairchild time proven pressure regulators, enabling remote control of the pneumatic pressure. Power is provided by 11-26 VDC and position is controlled by a 4-20mA signal or pulse clockwise or counterclockwise. The actuator is designed to lock in last place if power or signal are lost. The PAX1 is ideal when precise position control is required, and it has an optional analog feedback that transmits current position to the operator through an 4 to 20 mA Analog Feedback Signal. Adjustable motor speeds, customer set position limits and alarms are standard features.
- The PAX 1is available in a variety of configurations and NAMUR mounting interface allow it to be flexible for use as an industrial actuator, featuring a 1" (25 mm) maximum thrust rod stroke moving at speeds up to 60 mm/min and a maximum thrust of 650 lbf (2,890 N), all in a flameproof enclosure. The unit in inherently lock in last place (fail freeze) as the thrust rod maintains its position upon loss of signal or electrical power.
- The PAX1 can be actuated open loop using two optically isolated switch closure inputs (UP and Down) to move the actuator's thrust rod. The actuator will continue the move of the thrust rod in response to the inputs until either either of the adjustable stroke limits are reached.
- The PAX 1 also has an isolated 4-20 mA analog input to proportionally position the thrust rod anywhere within its 1" (25 mm) stroke. Optionally, a 1-5 VDC non-isolated analog input can be selected by an internal DIP switch.
- The actuator also includes two fully adjustable SPDT alarm relays (one High and one Low), providing critical positions within its stroke. The relays are latched so the alarm switch states are maintained when the power is disconnected.
- The actuator also features UP and DOWN buttons and a 5/16" (8 mm) female HEX socket to allow manual actuator movement, in order to facilitate commissioning.
Manifold Kits for T6000, T7800 and T7950 Transducers Current to Pneumatic (I/P or E/P)The Manifold Kits for the T6000, T7800 and T7950 Series Transducers are available for mounting 3, 5, 10 or 15 transducer units. These manifolds have a common supply port to all the transducers. Internal check valves in the inlet and outlet ports permit the installation and removal of individual transducers without affecting other units on the manifold. Supply port connections are provided on the end and rear of the manifold. Outlet ports are located on the rear and bottom of the manifold. Mounting brackets for flush or extended mounting from the back wall are available. These options allow the user to select the combination of supply ports, outlet ports and mounting configurations to maximize usage of available space.
Voice Coil EP, E/P, I/P Pressure Transducers (TXPD6000)The TXPD6000 I/P transducer is a field reversible unit that provides an output directly or inversely proportional to the input signal. Its six available output pressure ranges and six available input signal ranges meet most process and machine requirements. The TXPD6000 Series is designed for precision applications providing maximum versatility. In this explosion proof NEMA 4X configuration, the TXPD6000 is approved by FM, CSA and ATEX and ready for your installation in hazardous duty.
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.
