差动远传压力表既可对所测压力做现场指示又能转换为0—10mA或4—20mA的标准
电流信号输出。可以与Ⅱ型或Ⅲ型电动单元组合仪表中的二次仪表、调节器、计算单元及巡
回检测装置组成自动记录、调节、控制等系统。差动远传压力表按输入电压及输出电信号的
不同分为3 种型号:831 (220V AC 50Hz 0— 10mA)、832 (24V DC 4 — 20mA)、833
(220V AC 50Hz 4— 20mA)。
仪表适用于石油、化工、冶金、电路、轻工业等行业测量对铜合金无腐蚀作用的气体及
液体的压力。与此类隔离器连接后,可在各种腐蚀性的环境中使用。
8.30 series Pressure Gauge with differential transmitter is not only able to indicate the
pressure value, but also transform it into 0-10mA or 4-20mA, the standard current output
signals, with the secondary meter, regular, calculating unit and cyclic detector, the gauges
will become an system with automatic record, regulate and control.
It is used in petrochemical, metallurgy, electronic and light industry, suitable for the
gaseous or liquid medium that will not corrode the copper alloy and iron. Connected with
insulations, it could be used in corrosion environments.
