Description
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.
