Series 3730

Electropneumatic Positioner Type 3730-6

with HART

communication and pressure sensors

Application

Single-acting or double-acting positioner for attachment to

pneumatic control valves. Self-calibrating, automatic adapta

tion to valve and actuator.

Reference variable 4 to 20 mA

Travels 3.6 to 200 mm

Opening angles 24° to 100°

The positioner ensures a predetermined assignment of the valve

stem position (controlled variable x) to the electric input signal

(reference variable w). It compares the control signal received

from a controller to the travel or opening angle of the control

valve and issues a corresponding output signal pressure (output

variable y).

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 (Fig. 3)

• 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 various 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

•

Permanent storage of all parameters in non-volatile EEPROM

(protection against power failure)

•

Two-wire system with a small electrical load of 460

•

Adjustable output pressure limitation

•

Activatable tight-closing function

•

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 (T 8389-1 EN), suitable

for valves for throttling and on/off service with additional

partial stroke test for valves in safety-instrumented systems

•

Certified according to IEC 61508/SIL

•

Pressure sensors to monitor the supply air and signal pressure
