Flowserve Logix 3800 Digital Positioner

Logix

Logix positioners are synonymous with innovation, quality and performance, whether mounted on world-renowned heritage brand valves from Flowserve or any other OEM’s valve, actuator or positioner.

Key Features & Benefits:

• Reliable, trouble-free performance
• Design provides protection from dirt and water egress, impact, and vibration
• Easy configuration and calibration
• Predictive diagnostics powered by VavleSight DTM
• Application versatility
• Safe, non-incendive, and explosion-proof design
• Up to 80% more air capacity with minimal air consumption

Logix 3800 Digital Positioners are compatible with linear and rotary valves and actuators and provides high reliability in tough environments.  The Logix 3800 Digital Positioners offer broad application versatility with communication technologies, including analog, HART, Foundation Fieldbus, 4-20, or discrete I/O signals.  These digital positioners are more reliable than ever, featuring trouble-free performance ensured by the shielded, dual-element, non-contact, magneto-resistive position sensor and temperature-compensated, dual-poppet pneumatic relay.  Enjoy quick calibration and one-button setup for easy use, and get ahead of any problems with the five on-board pressure sensors that enable operators to identify any developing issues.  

Robust and reliable
Trouble-free performance in demanding applications is ensured by the shielded, dual-element, non-contact, magneto-resistive position sensor and temperature- compensated, dual-poppet pneumatic relay. The rugged, modular design provides protection from dirt and water ingress (IP-66), impact and vibration.

Easy configuration and calibration
Innovative quick calibration feature greatly simplifies commissioning. One-button setup automatically configures the zero, span and gain of the positioner for most valves in less than 60 seconds.

Predictive diagnostics
Powered by ValveSight DTM, the Logix 3800 has five on-board pressure sensors that enable operators to identify and assess the severity of developing problems so action can be taken before a critical event.

Application versatility
Broad application versatility with industry-leading communication technologies, including analog, HART, Foundation Fieldbus, 4-20 or discrete I/O signals. Optional module to remotely locate the positioner from the control valve. Compatible with a variety of valve and actuation configurations

Increased safety
Intrinsically safe, non-incendive and explosion-proof design from -52°C to 85°C (-62°F to 185°F) ensures safe, reliable operation in hazardous conditions. Certified for use in explosion-proof Exd IIC hazardous locations.

Greater air capacity
Up to 80% more air capacity with minimal air consumption is made possible by the double-poppet technology.
