Product Description

Product Overview

In the realm of industrial process control and monitoring, accurate and reliable analytical measurements are of paramount importance. Emerson, a global leader in automation solutions, presents the Rosemount Two-Wire Analytical Transmitters 5081, a state-of-the-art product designed to meet the diverse needs of various industries. This transmitter is engineered to provide precise measurements of multiple parameters in a wide range of process liquids, ensuring optimal process control and enhanced operational efficiency.

Specification

Conductivity and Resistivity
When it comes to conductivity and resistivity measurements, the 5081 transmitter offers great versatility. It can work with both contacting and toroidal sensors for conductivity measurement. Conductivity is a measure of a solution's ability to conduct an electric current, while resistivity is its inverse. In industries like semiconductor manufacturing, where ultrapure water is used, accurate resistivity measurement is vital to ensure the quality of the final product. In chemical processing plants, conductivity measurements can help in monitoring the concentration of certain chemicals in a solution. 

Digital Communication Protocols

The 5081 transmitter offers two digital communication protocol options: HART (Highway Addressable Remote Transducer) and Foundation Fieldbus. HART communication allows for two-way communication between the transmitter and a host system, such as a PLC (Programmable Logic Controller) or a DCS (Distributed Control System). It enables users to access advanced features like remote configuration, calibration, and troubleshooting. Foundation Fieldbus, on the other hand, is a digital, serial, two-way communication system that provides a high-speed, reliable connection for more complex process control applications. These communication protocols facilitate seamless integration of the transmitter into modern industrial automation systems.
