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.
