Fig. 3304 Double-Acting Rotary Smart Positioner Order Information Econ series 3300 Smart Positioner for quarterturn actuators in double acting version. This positioner regulates and checks accurately the stroke of the valve, according to an input signal of 420mA, and optimizes by means of the built in microprocessor the performances of the positioner. The positioner offers unique functions such as automatic calibration, PID regulation and adaptation of the control characteristics. Optionally the positioner can be supplied with pressure gauges or extra modules, which can provide 420 mA feedback signal and HART protocol communication. Assembly on actuators according to (NAMUR) VDI/VDE 3845. The positioner is supplied complete with the required mounting set. Features Model: Quarter turn Display: Yes Stroke: 0 to 90 degrees Communication: None Feed pressure: 1.4 to 7 bar Temperature range: 30 to +85 grC Material housing: Aluminium Operation actuator: Doubleacting Actuation: Electro/pneumatic Input signal: 420mA Feedback: None Supply voltage (reported): Via loop Mounting kit: Yes Material shackle: Steel Pressure and Temp Range Supply pressure Ambient temperature Ambient humidity Protection class Additional information The Econ® series 3300 Smart Positioner functions on the basis of an electronic flap/nozzle system. Via the local LCD display the user can simple check the status of the positioner. The autocalibration makes a fast and simple commissioning possible. The low air consumption and low voltage requirement (8,5V) help to lower operational costs of an installation. The positioner functions with most common process controllers. The accuracy and fast reaction time of the Econ® series 3300 Smart Positioner strongly improves the control characteristics of the control valve and the valve system feedback. The positioner will function normally even during sudden changes in air supply pressure and/or an environment with strong vibrations. Properties/Advantages Fast commissioning due to autocalibration Optimization by PID algorithm Clearly readable LCD display Low air and power consumption Less sensitive to varying air quality “Tight shut”
