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.

Uniquely designed by Fairchild, the T6100 "Lock in Last Place" I/P 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.
