Model T7800 Electro-Pneumatic I/P, E/P Transducer

Brand: Fairchild Industrial Products
High performance at economical process is available from the Rotork Fairchild T7800 series of piezo-ceramic actuated I/P transducer. These units offer state of the art accuracy up to 0.15% FS. 

The disc actuation mechanism provides a product that is totally impervious to shock, vibration and positional orientation. In the Extended Range units, an additional Relay Section amplifies the output pressure to obtain up to 0-120 psi [0-8.0 BAR], (0-800 kPa) output. 

The T7800 series is approved for Intrinsic Safety and Non-Incendive use carries FM, CSA, ATEX and IECEx approvals.
Features
  • 18 available output ranges
  • Accuracy as low as 0.15%
  • Field Reversible Feature
  • RFI/EMI Protection
  • Internal Electronic Feedback and Piezoelectric Actuator
  • Damping Adjustment
  • Split range operation
  • NEMA 4X, Type 4 Enclosure and IP65 rated
  • FM, CSA, ATEX and IECEx approvals
