Quick Overview

SAMSON 3730-3 HART Positioner 

Special features

•Simple attachment to common linear and rotary actuators with SAMSON direct attachment interface (Fig. 1), NAMUR rib (Fig. 2), valves with rod-type yokes acc. to IEC 60534-6-1 or rotary actuators acc. to VDI/VDE 3845.
•Any desired mounting position.
•Simple one-knob, menu-driven operation.
•LCD easy to read in any mounting position due to selectable reading direction.
•Configurable with a PC over the SSP interface using the TROVIS-VIEW software.
•Variable, automatic start-up with four different initialization modes.
•Preset parameters – only values deviating from the standard 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.
•All parameters saved in EEPROM (protection against power failure).
•Two-wire system with a small electrical load between 300  and 410  depending on the version (see Table 1on datasheets).
•Adjustable output pressure limitation.
•Tight-closing function can be activated.
•Continuous monitoring of zero point.
•Integrated temperature sensor and operating hours counter.
•Two standard configurable 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 (see T 8389 EN), suitable for valves for throttling and on/off service with additional partial stroke test for valves in safety-related applications.
•Certified according to IEC 61508 / SIL.


•Type 3730-3 · Electropneumatic positioner with LCD, operable on site, local communication using SSP interface, EXPERTplus diagnostics with HART® communication
