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.
This video walks you through the quick and easy steps to calibrate the Logix 3800 positioner. One-button setup automatically configures the zero, span and gain of the positioner for most valves in less than 60 seconds.
This video reviews the settings for the 8 DIP switches on the Logix 3800 positioner.
This video shows you how easy it is to mount a Logix 3800 digital positioner to a Valtek Mark One linear control valve. It also shows how easy it is to retrofit valves fitted with older Logix 3000-model positioners with the new Logix 3800 positioner by using an adapter bracket that enables use of the existing mounting bracket.
In this video, you will learn how to mount a Logix 3800 digital positioner to a Valtek rotary valve that is configured with a Valtek VR actuator.
This video shows you how easy it is to mount a Logix 3800 digital positioner to an Automax rotary actuator using the Namur standard mounting configuration.
This video shows you how easy it is to mount a Logix 3800 digital positioner to a Flowserve Flowact single-acting, pneumatic diaphragm actuator. It explains the mounting differences between air-to-open and air-to-close configurations using a direct mount block.
