3730-3 Electropneumatic positioner

Electropneumatic positioner with HART® communication

SAM DIGITAL 

Die-cast aluminum or stainless steel housing

Attachment to linear actuators according to IEC 60534-6, VDI/VDE 3847, or SAMSON integral attachment

Attachment to rotary actuators according to VDI/VDE 3845

Attachment to double-acting actuators with Type 3710 Reversing Amplifier

Integrated EXPERTplus diagnostics for control valves

Any desired mounting position of the positioner (but not suspended)

Simple one-knob, menu-driven operation

Easy-to-read display in any mounting position thanks to rotatable reading direction

Configurable with a computer over the SSP interface using the TROVIS-VIEW software

Variable automatic start-up thanks to 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 (substitution) initialization mode allows the positioner to be started up in case of emergency whilst the plant is running without having to change the valve position.

All parameters saved in non-volatile EEPROM

Two-wire system with small electrical load of 410 Ω

Adjustable output pressure limitation

Adjustable tight-closing function

Automatic zero monitoring

Integrated temperature sensor and operating hours counter

Two standard programmable position alarms

Self-diagnostics

Messages as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter

DTM file available for integration into FDT frame applications according to specification 1.2
