隔爆型,本安型带热电偶电阻温度变速器,SBWR-4180/440D,
主要特点:
● 采用硅橡胶或环氧树脂密封结构,因此耐震、耐湿,适合在现场环境中安装使用;
● 现场安装在热电偶,热电阻的接线盒内使用,直接输出4-20mA、0-10mA的输出信号。这样既节约了昂贵的补偿导线费用,又提高了信号远距离传输过程中的抗干扰能力;
● 热电偶变送器具有冷端自动补偿功能;精度高、功耗低,使用环境温度范围宽,工作稳定可靠;
● 适用范围广,即可以与热电偶,热电阻形成一体化现场安装结构,也可以作为功能模块安装在检测设备中和仪表盘上使用:
工作原理:
热电偶或热电阻传感器被温度转换成电信号,再将信号送入变送器的输入网络,该网络包含调零和热电偶补偿等相关电路。经调零后的信号输入到运算放大器进行信号放大,放大的信号一经V/I转换器运算处理后以DC4-20mA电流输出;另一路经A/D转换器处理后到表头显示。变送器的线性化电路有两种,均采用反馈方式。对热电阻传感器,用正反方式校正,对热电偶传感器,用多段折线逼近法进行校正。一体化数字显示温度变送器LCD显示的采用两线制方式输出。
