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%/℃ 铂电阻元件WZPK2-165SA,WZPK2-166SA,WZPK-263S,WZPK-264S,WZPK-265S,WZPK-266S,.WZPK2-265SA,WZPK2-266SA,WZPK-363S,WZPK-364S,WZPK-365S,WZPK-366S,WZPK2-365SA,WZPK2366SA,WZPK-463S,WZPK-464S,WZPK-465S,WZPK-466S,WZPK2-465SA,WZPK2466SA,WZPK-563S,WZPK-564S,WZPK-565S,WZPK-566S,WZPK2-565SA,WZPK2566SA,WZPK-173S,WZPK-174S,WZPK-175S,WZPK-176S,WZPK2-175SA,WZPK2-176SA,WZPK-273S,WZPK-274S,WZPK-275S,WZPK-276S,WZPK2-275SA,WZPK2-276SA,WZPK-373S,WZPK-374S,WZPK-375S,WZPK-376S,WZPK2-375SA,WZPK2376SA,WZPK-473S,WZPK-474S,WZPK-475S,WZPK-476S,WZPK2-475SA,WZPK2476SA,WZPK-573S,.WZPK-574S,WZPK-575S,WZPK-576S,WZPK2-575SA,WZPK2576SA,WZPM-101U,WZPM-201U,WZPM—002U,WZPM-102U,WZPM-202U,WZPM—001,WZPM-101S,WZPM-201S,WZPM-002,WZPM-102,WZPM-202,WZPM—301,WZP-011S,WZP-012S,WZP-013S,WZP-014S,WZP-015S,WZP-203S,WZP-205S,WZP-018,WZP-0110,WZP-2012,装配式铂电阻(采用引进铂电阻元件)WZP-106S,.WZP2-0110,WZP-1212U,WZP-1312U,WZP-2212U,WZP-2312U,WZP-3212U,WZP-3312U,WZP-4212U,WZP-4312U,WZP-6212U,WZP-6312U,WZP-270U,WZP-270S,WZP-26S,WZP-236S,WZP2-236S,WZP-1212A,WZP2-1212A,WZP-1312A,WZP2-1312A,WZP-2212A,WZP2-2212A,WZP-2312A,WZP2-2312A,WZP-3212A,WZP2-3212A,WZP-3312A,WZP2-3312A,.WZP-4212A,WZP2-4212A,WZP-4312A,WZP2-4312A,.WZP-6212A,WZP2-6212A,WZP-6312A,WZP2-6312A,WZPT-31,WZP-74S,WZP2-74S,WZPK-133S WZPK-134S WZPK-135S WZPK-136S,WZPK-233S,WZPK-234S,装配式热电阻WZPK-235S,WZPK-236S ,WPK-333S WZPK-334S,WZPK-335S,WZPK-336S,WZPK-433S WZPK-434S WZPK-435S WZPK-436S WZPK-533S WZPK-534S WZPK-535S WZPK-536S WZP-621 WZP-6312A WZP2-631 WZP2-6212A WZPK2-135SA WZPK2-136SA WZPK2-235SA WZPK2-236SA WZPK2-335SA WZPK2-336SA WZPK2-435SA WZPK2-436SA WZPK2-535SA WZPK2-536SA, WZPK-163S WZPK-164S WZPK-165S WZPK-166S WZPK-263S WZPK264S WZPK-265S WZPK266S WZPK363S WZPK363S WZPK364S WZPK365S WZPK-366S WZPK-463S WZPK-464S WZPK-465S WZPK-466S .WZPK563S WZPK-564S WZPK-565S WZPK-566S WZPK2-165SA WZPK2-166SA WZPK2-265SA WZPK2-266SA WZPK2-365SA WZPK2-366SA WZPK2-465SA WZPK2466SA WZPK-565SA WZPK2-566SA, WZP-235T, WZP2-235TWZP-130-F, WZP-230-F, WZP-330-F, WZP-430-F, WZP 2-130-F, WZP 2-230-F, WZP 2-330-F, WZP 2-430-F, WZP-131-F, WZP-231-F, 套管式热电阻 WZP-331-F, WZP-431-F, WZP 2-131-F, WZP 2-231-F, WZP 2-331-F, .WZP 2-431-F, WZC-130-F, WZC-230-F, WZC-330-F, WZC-430-F, WZPN-130, WZPN-230, WZPN-330, WZPN-430, WZPN 2-130, WZPN 2-230, WZPN 2-330, WZPN 2-430, WZPN -131, WZPN-231, WZPN-331, WZPN-431, WZPN 2-131, WZPN 2-231, .WZPN 2-331, WZPN 2-431, WZPM-631, WZPM2-631, WZCN-130, WZCN-230, WZCN-330, WZCN-430, WZP-2328, WZP2-2328, WZP-93C1, WZP2-93C1, WZP-93C2, WZP2-93C2, WZP-633, WZP2-633, WZP-634, WZP2-634, WZP-4318, WZP2-4318, WZP-731, WZP2-731, WZP-120, WZP-121, 耐腐型、耐磨型热电阻 WZP-130, WZP-131, WZP2-120, WZP2-121, WZP2-130, WZP2-131, WZC-120,WZC-130, WZP-220, WZP-221, WZP-230, .WZP-231, WZP2-220, WZP2-221, WZP2-230,WZP2-231, WZP-221A, WZP2-221A, WZC-220, WZC-230, WZC-220A, WZP-220, WZP-221WZP-230, WZP-231, WZP2-220, WZP2-221, WZP2-230, WZP2-231, WZP-220A, WZP2-220A, WZC-220, WZC-230, WZC-220A, WZP-320, WZP-321, WZP-330, WZP-331, WZP2-320, WZP2-321, WZP2-330, WZP2-331, 可动式热电阻WZC-320, WZC-330, WZP-420, .WZP-421, WZP-430, WZP-431, WZP2-420, WZP2-421, WZP2-430, WZP2-431, WZP-420A, WZP2-420A, WZP-420, WZC-430, WZP-420, WZP-421, WZP-430, WZP-431, WZP2-420, WZP2-421, WZP2-430, WZP2-431, WZP-420A, WZP2-420A, WZC-420.
