Product Description

Product Overview

The Flowserve Model 3821 - 28EA - D43R - 0110 - 00 Logix 3800 Series Digital Positioner is a state - of - the - art device designed to revolutionize valve control and monitoring in industrial settings. As part of Flowserve's renowned Logix 3800 series, it combines advanced technology, high - end performance, and user - friendly features to meet the diverse needs of various industries.

Specification

Product Overview
One of the standout features of the Model 3821 - 28EA - D43R - 0110 - 00 is its innovative quick calibration feature. Commissioning the positioner is a breeze, thanks to the one - button set - up function. In less than 60 seconds, this feature automatically configures the zero, span, and gain of the positioner for most valves. This significantly reduces the time and effort required for installation and start - up, minimizing downtime during system commissioning or when replacing existing positioners. The user - friendly interface, which is independent of the control system, further simplifies configuration, operation, and system diagnostics. Operators can easily access and adjust settings, view diagnostic information, and monitor the positioner's performance with a single view.

Supply Pressure

Powered by the ValveSight DTM, the Logix 3800 series digital positioner is equipped with five on - board pressure sensors. These sensors enable operators to identify and assess the severity of developing problems in the valve and actuation system. By continuously monitoring pressure levels and other critical parameters, the positioner can detect early signs of issues such as leaks, blockages, or component wear. This predictive diagnostic capability allows plant operators to take proactive measures before a critical event occurs, reducing the risk of unexpected equipment failures and costly production interruptions. It also helps in optimizing maintenance schedules, as maintenance activities can be planned based on the actual condition of the equipment rather than on a fixed - interval basis.
