Description

SAMSON 3725 Electropneumatic Positioner

SAMSON Type 3725 Positioner

Application

Single-acting positioner for attachment to pneumatic globe and rotary valves. Self-calibrating, automatic adaptation to valve and actuator. Reference variable 4 to 20 mA Travel 5 to 50 mm Opening angle 24 to 100°

The positioner ensures a predetermined assignment of the valve position (controlled variable x) to the input signal (reference variable w). It compares the input signal received from a control system to the travel or rotational angle of the valve and issues a corresponding output signal pressure (output variable y).

Special features

• Electropneumatic positioner
• Housing of polyphthalamide
• Attachment to linear actuators according to IEC 60534-6 or SAMSON integral attachment
• Attachment to rotary actuators according to VDI/VDE 3845
•  Attachment to double-acting actuators with Type 3710 Reversing Amplifier
• Easy operation with intuitive navigation menu using three capacitive keys
• Easy-to-read display in any mounting position thanks to rotatable reading direction
• Variable automatic start-up
• Preset parameters
• All parameters saved in non-volatile EEPROM
• Tight-closing function can be activated
• Automatic zero monitoring
• Non-contact position sensing
• Unaffected by environmental effects and steam hammering

Accessories
