Positioner attachment

The Type 3730 Electropneumatic Positioner can be attached di

rectly to the Type 3277 Actuator (240 to 700 cm²) over a con

nection block.

In actuators with fail-safe action “Actuator stem extends", the

signal pressure is routed over an internal bore in the actuator

yoke to the actuator. In actuators with fail-safe action “Actuator

stem retracts”, the signal pressure is routed to the actuator over

ready-made external piping.

Using a bracket, the positioner can also be attached according

to IEC 60534-6-1 (NAMUR recommendation). The positioner

can be mounted on any side of the control valve.

A pair of universal brackets is used for the attachment to

Type 3278 Rotary Actuators or other rotary actuators accord

ing to VDI/VDE 3845. The rotary motion of the actuator is

transferred to the positioner over a coupling wheel with position

reading.
