Germany original Samson control valve positioner 3730-3 Electropneumatic positioner with HART® communication
single-acting or double-acting positioner for attachment to pneumatic control valves. Self-calibrating, automatic adaptation to valve and actuator.
The positioner ensures a predetermined assignment of the valve position (controlled variable x) to the input signal (set point w). It compares the input signal received from a control system to the travel or rotational angle of the control valve and issues a corresponding output signal pressure (output variable y).
• Any desired mounting position of the positioner (but not suspended) • Simple single-knob, menu-driven operation
• LCD easy to read in any mounted position due to selectable reading direction
• Confi gurable with a PC over the SSP interface using the TROVIS-VIEW software
• Variable, automatic start-up with four different initializati on modes
• Preset parameters - only values deviating from the stan dard need to be adjusted
• Calibrated travel sensor without gears susceptible to wear
• Sub initialization mode (substitution) allows the positioner to be started up in case of emergency whilst the plant is running without the valve moving through the whole travel range.
• Permanent storage of all parameters in EEPROM (protected against power failure)
• Two-wire system with a small electrical load of 410 Ω
• Adjustable output pressure limitation.
• Activatable tight-closing function
• Continuous monitoring of zero point
• Integrated temperature sensor and operating hours counter
• Two standard programmable position alarms
• Self-diagnostics; alarms as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter
• Integrated EXPERTplus diagnostics for control valves

Principle of operation
The positioner is mounted on pneumatic control valves and is used to assign the valve position (controlled variable x) to the control signal (set point w). The positioner compares the elec-tric control signal of a control system to the travel or rotationalangle of the control valve and issues a signal pressure (output variable y) for the pneumatic actuator.
