Samson 3730 Electro-pneumatic Valve Positioner Introduction

Samson 3730 Electropneumatic Valve 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)


Samson 3730 Electro-pneumatic Valve Positioner Feature

Simple attachment to all common linear and rotary actuators with interface for SAMSON direct attachment,

NAMUR rib or valves with rod-type yokes according to

IEC 60534-6-1, or to rotary actuators according to VDI/

VDE 3845

• Any desired mounting position of the positioner

• Simple single-knob, menu-driven operation

• LCD easy to read in any mounted position due to selectable reading direction

• Variable, automatic start-up

• Preset parameters - only values deviating from the standard need to be adjusted

• Calibrated travel sensor without gears susceptible to wear

• Permanent storage of all parameters in EEPROM (protected

against power failure)

• Two-wire system with a small electrical load of 300 Ω

• Tight-closing function can be activated

• Continuous monitoring of zero point

• Two standard programmable position alarms
