深圳湾边贸易代理美国Altek 334A毫安回路校准仪
产品说明:
可从任意预定位置来凋节输出值
•采用数字电位器调值简化操作
•具有校验所有回路4 -20毫安的功能
•产生0.00-24.00毫安或4-20毫安量程的-25.0 ~125.0%信号
•可测量到52.00毫安
•提供两线制回路电源至27V
•连接回路电源为3~45 V直流电压
•测量回路电源直流电压
•快速输出三个任意设定的中间值
Altek334A毫安回路校准仪专门用来测量和校验回路。具有4-20毫安信号所有的回路校准功能，可作为mA表及两线制24mA直流模拟信号器并且能测量回路电源电压，是一个多功能回路校准仪，可以直接输出毫安值，也可以以4-20mA的百分比形式输出。
Altek334A毫安回路校准仪为两线制变送器供电的同时可显示电流。当作为过程控制用的变送器拆去修理时，可简便地用Altek334A毫安回路校准仪代替控制器，用手动调节进行控制。
334A毫安回路校准仪出厂标配﹕安装固定的测试笔、9V电池及说明书
