(S/HART)
• Position sensor
Very high resolution conductive plastic potentiometer
• Microprocessor controlled electronics
for signal processing, control and driving the piezoelectric positioning system; setpoint entry and
power supply are via a 4 ... 20 mA standard signal.
• Operating elements
The device can be set (configuration and parametrization) locally via three inside keys. An inside, 8-
digit, 16-segment LC display is provided, which can also show the setpoint or actual value.
• Positioning system
A piezoelectric positioning system serves to drive the valve actuator.
• Position repeater (option)
via 2 inductive proximity switches (initiators)
• Electrical interfaces
Cable bushing (M20x1.5) with screw terminals
• Pneumatic interfaces
G1/4’’ interior thread
• Housing
Aluminium housing (hard anodized and plastic-coated) with swing-up cover and captive screws.
• Attachment
to linear actuators to NAMUR recommendation (DIN IEC 534 T6) or to part-turn actuators to
VDI/VDE 3845.
Option: integral attachment to Bürkert continuous valves
