I.Product Overview
Brand and Series:
YOKOGAWA(Yokogawa Electric,a leading global provider of industrial automation and process control solutions,with core businesses including DCS systems,analytical instruments,flow meters,and pressure transmitters).
Product Type:Intelligent temperature transmitter(or temperature signal converter;the MAC series is typically used for collecting,converting,and transmitting temperature signals in industrial fields).
Model Positioning:
The MAC2-B may be an upgraded model of Yokogawa’s YTA series temperature transmitter(the”B”may represent the second generation or a version with specific features),or a customized temperature measurement module(such as one that supports multiple inputs or special communication protocols).
It may also be a dedicated transmitter designed for use with specific systems(such as DCSs and PLCs).This should be determined based on the specific application scenario.
