The Fairchild T5200 Transducer is an electro-pneumatic device that is controlled by a 4-20 mA current in a control loop. It featuers a fast response to input signal changes, resulting in faster loop control and savings in process materials.
The Fairchild T5200 Transducer is an electropneumatic device that is controlled by a 4-20 mA current in a control loop. This device is made up of two sections, the Signal Conversion Section and the Pneumatic Section.
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.
