一、产品简介    Product introduction   

        SBWZ热电阻温度变送器是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）。将热电阻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阻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。   

        SBWZ thermistor temperature transmitter isa field mounted temperature transmitter unit in the DDZ-S series instruments. Itadopts a two wire transmission method (two wires serve as power inputs and acommon transmission line for signal output). Transforming the thermistor signalinto a 4-20mA output signal that is linear with the input electrical signal orthe measured temperature, the transmitter module can be installed in thejunction box of the thermistor to form an integrated structure. The rail typecan be installed on the C45 rail inside the control cabinet. As a newgeneration of temperature measuring instruments, it can be widely used inindustrial sectors such as metallurgy, petrochemicals, electricity, lightindustry, textiles, food, national defense, and scientific research.
