Digital Positioners - Logix 3800
Compatible with linear and rotary valves and actuators, Logix 3800 digital positioner delivers high reliability in tough environments. It provides unparalleled modularity and versatility within a single unit. Its ability to handle double- or single-acting, linear and rotary applications reduces inventory and operating costs. Installation is simplified with an innovative, one-button quick calibration feature.... Read more Read less
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.
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.
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
Intrinsically safe, non-incendive and explosion-proof design from -52°C to 185°C (-62°F to 365°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.
