➢ LCD display enables users to monitor the positioner status.

➢ User will easily understand the method of using 4 buttons because it work same in all versions of firmware interfaces.

➢ When unexpected situation like momentary blackout happens, our positioner boot-time only take 0.5 second and this can minimize the travel of valve which consequentially increase the safety of system.

➢ Positioner operates normally even there are sudden changes in supply pressure and / or high vibration environment.

➢ YT-3301 remote positioner is stronger on high temperature and vibration environment because it is separated into remote sensor and positioner.

➢ The method of Auto Calibration is very simple.

➢ As an advantage of having very low air consumption, It could greatly reduce operating costs in large-scale plants.

➢ It is compatible with most of controllers.

➢ Orifices can be installed even in the field to minimize the hunting occurrence and optimize operating conditions.

➢ Various information about positioner can be processed by HART communication (HART option)

➢ Valve system becomes more stable by outputting analog feedback signal. ➢ Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and User Set which user can make 5 or 18 points characterizations.

➢ Tight Shut – Close and Shut - Open can be set.

➢ PID parameters can be adjusted in the field without any additional communicator.

➢ A/M switch can be used to direct supply air to the actuator or to manually operate the positioner or valve without any signal.

➢ Split range 4~12mA or 12~20mA can be set.

➢ Operating temperature for remote sensor of YT-3301 is -40 ~ 120℃. Operating temperature for positioners is -30 ~ 85℃ or -40 ~ 85℃ (Please check certified explosion proof temperature)

➢ Hand calibration function can set Zero point or End point manually.

➢ It has IP66, Type 4X(FM) protection grade.

➢ Polyester powder coating resists the corrosion process. (except YT-3350).
