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。 技术参数 1.输入信号:热电偶:K、E、J、B、S、T、N;热电阻:Pt100、Cu50、 Cu100、(三线制、四线制),智能型温度变送器的输入信号可通过PC机或手操器任意设置; 2.输出信号:在量程范围内输出DC4-20mA电流信号,与热电偶、热电阻的输入信号成线性或与温度成线性。智能型温度变送器输出DC4-20mA电流信号同时叠加符合HART标准协议通信信号; 3.基本误差:0.5%FS;0.2%FS;智能型0.2%FS; 4.接线方式:二线制;三线制; 5.显示方式:四位LCD显示温度,智能型四位LCD可通过PC机或手操器设定使之显示现场温度,传感器值,输出电流和百分比例中的任一种参数; 6.工作电压:普通型12∽35V DC;智能型12V∽45V DC;额定工作电压为24V DC; 7.允许负载电阻:500Ω(24VDC供电);极限负载电阻R(max)=50(Vmin-12),例如在额定工作电压24V DC时,负载电阻可0-600Ω范围内选择使用。 8.工作环境: a:环境温度 -25∽80℃(常规型) -25∽70℃(数显型) b:相对温度 5%∽95% c:机械振动f≤50HZ,振幅≤0.15mm d:无腐蚀气体或类似的环境; 9.温度影响系数:δ≤0.05%/℃ 装配式热电偶WRE2-12B, WRN-13B, WRE-13B, WRN2-13B, WRE2-13B, WRN-14B, WRE-14B, WRN2-14B, WRE2-14B, WRN-15B, WRE-15B, WRN2-15B, WRE2-15B, WRN-15AB,.
