Rotork YT-3700 and YT-3750 pneumatic smart positioners

Tuesday, 16 June, 2020 | Supplied by: Rotork Australia


The Rotork YT-3700 and YT-3750 pneumatic smart positioners employ continuous monitoring and graphic display of valve position, setpoint target over time and internal circuit board temperature over time. With single- and double-acting configurations available, they are said to provide reliable control of pneumatic valve systems for linear and rotary applications.

Valve diagnostic information to NE107 standard is provided, with Hart 7 communication protocol included as standard and a display for all settings and local device interaction.

The enhanced diagnostic package offers position-over-time continuous monitoring, and graphical visualisation trough Device Description (DD) and Device Type Manager (DTM) files. Additionally, valve signature, advanced step tests and partial stroke testing (PST) can be operated from local or remote positions. Auto-tuning functionality and non-contact sensor are included for high-frequency operating valves and an enhanced lifetime.

The steady state deviation analysis that they provide can detect friction in the valve or actuator, leakage in pneumatics and instances where there is insufficient supply pressure. A deviation timeout alarm occurs when the difference between the target position and the actual position exceeds the pre-set deviation alarm point.

To match Emergency Shutdown (ESD) systems for on-off applications, the YT-3700 range offers a full package of offline diagnostic tests that include both valve signature and partial stroke test. All information can be stored on the device or downloaded.

The YT-3700 and YT-3750 are certified to ATEX/LEXIEX standards and can operate in temperatures as low as -55°C.
