一、产品简介    Product introduction

        SBWR热电偶温度变送器是DDZ-S系列仪表中的现场安装式温度变送单元。它采用二线传送方式（两根导线作为电源输入，信号输出的公用传输线）。将热电偶信号变换成与输入电信号或被测温度成线性的4~20mA的输出信号，变送器模块可以安装于热电偶的接线盒内与之形成一体化结构。导轨式可以安装在控制柜内C45导轨上。它作为新一代测温仪表可广泛应用于冶金、石油化工、电力、轻工、纺织、食品、国防以及科研等工业部门。

       SBWRthermocouple temperature transmitter is a field mounted temperature transmitterunit in the DDZ-S series instruments. It adopts a two wire transmission method(two wires serve as power inputs and a common transmission line for signaloutput). Transform the thermocouple signal into a 4-20mA output signal that islinear with the input electrical signal or the measured temperature. Thetransmitter module can be installed in the junction box of the thermocouple toform an integrated structure. The rail type can be installed on the C45 railinside the control cabinet. As a new generation of temperature measuringinstruments, it can be widely used in industrial sectors such as metallurgy,petrochemicals, electricity, light industry, textiles, food, national defense,and scientific research.
