横河川仪EJA120A智能微差压变送器
横河川仪智能微差压变送器EJA120A用于测量液体、气体和蒸汽的液位、密度和压力，然后将其转变成4-20mADC的电流信号输出。EJA120A也可与BRAIN TM 手操器、HART ® 手操器(YHC5150X等)、CENTUMCSTM 、FieldMate互相通讯，通过它们进行设定、监控等。
主要技术参数
一、输出：2 线制,4～20mA DC 输出,数字通讯,可编程设定线性或平方根输出方式,BRAIN 或HART FSK协议加载在 4～20mADC信号上。
二、电源电压
a、10.5～42V DC(普通型和隔爆型)；b、10.5～30V DC(本安型、n型或非易燃型)；c、10.5～32V DC(带避雷保护时)；d、BRAIN和HART协议通讯时至少16.4V DC。
三、环境温度：- 25～85℃( - 13～176°F )
四、接液温度：- 25～85℃( - 13～176°F )
五、密封等级：IP67
