Rotork Positioners YT-3300 & YT-3400

Back to Latest News Page

Norman Equipment is excited to introduce Rotork’s YT-3300 and YT-3400 Smart Positioner product featuring torque motor technology with communications. Smart Positioners use a microprocessor to position the valve actuator while monitoring and recording data. They function similarly to an electro-pneumatic analogue-type positioners, except the electronic signal conversion is digital rather than analogue. Smart positioners are extremely accurate, use less air, and allow for online digital diagnostics.

Rotork Positioners

 

Smart Positioners YT-3300 Design Features:

  • Auto calibration: Simple menu structure with options to auto calibrate all parameters or zero and end points only.
  • LCD Display: Alphanumeric digital display for process values and calibration.
  • Partial Stroke Test (PST): Fully adjustable Partial Stroke Test. All functionality can be performed and selected locally, through push buttons, or remotely with communication protocol.
  • Feedback signal: Analogue and Digital feedback signals with 4 to 20 mA, mechanical and proximity switch options (Limit switch options for YT-3300 and YT-3500 models).
  • PID control: Pre-calibrated and user configurable variables via front panel pushbutton menu.
  • Auto / Manual switch: Enables closed-loop automatic valve position control or manual positioning via the A/M switch. The manual mode is useful for troubleshooting, calibration, system testing, or as a manual bypass.
  • HART communication: Allows commands, position feedback, and diagnostics to be sent digitally over the current loop.
  • Front panel pushbuttons for configuration: 4 robust and positive acting pushbuttons for field configuration.
  • Remote Mounting Options (YT-3301 model): Remote sensor via cable to enable the positioner to be mounted away from extreme temperature.  

Smart Positioners YT-3400 Design Features:

  • Explosion / Flameproof Housing: Global certification for Zone 1 and Division 1 installations.
  • Auto calibration: Simple menu structure with options to auto calibrate all parameters or zero and end points only.
  • LCD display: Alphanumeric digital display for process values and calibration.
  • Partial Stroke Test (PST): Fully adjustable Partial Stroke Test, with single or double set positions, all functionality can be performed and selected locally, through push buttons, or remotely with communication protocol.
  • Feedback signal: Analogue feedback signals with 4 to 20 mA, mechanical and transistor switch options.
  • Auto / Manual switch: Enables closed-loop automatic valve position control or manual mode is useful for troubleshooting, calibration, system testing, or as a manual bypass.
  • PID control: Pre-calibrated and user configurable variables via front panel pushbutton menu.
  • HART communication: Allows commands, position feedback and diagnostics to be sent digitally over the current loop.
  • Front panel pushbuttons for configuration: 4 robust and positive acting pushbuttons for field configuration.
