applications: steam turbine control systems, process control systems, pulp/paper industry, petrochemical process control, roller gap position
industries: general industry
description: the iem-422 is a line-powered lvdt/rvdt compatible current transmitter, designed for industrial process control applications. the iem-422 consists of a din rail mount power supply and an lvdt signal conditioner module, pre-configured to supply a 4 to 20 ma output from a 115 or 230 volt ac supply. the iem-422 supplies an ac sine wave excitation to the lvdt and then demodulates and amplifies the lvdt output. a full-wave synchronous demodulator eliminates quadrature and harmonics to maximize external noise rejection.
features:
rugged nema-13 rated enclosure
conduit ports for easy connection
pre-configured 4-20ma output signal
bolt holes for easy mounting
multiple lvdt master/slave capability
典型应用: 汽轮机节流阀阀位反馈,纸浆工业,石化工业过程控制,辊筒间隙过程控制
行业: 工业控制
产品描述:
iem 422是一款电流变送器,由电源和lvdt信号处理模块组成,115v或230vac供电,输出为4-20ma。iem 422提供正弦交流电压以驱动lvdt,然后调制解调并放大lvdt的输出。全波同步解调可最大限度的消除方波输出和噪音。iem 422采用坚固的nema 13外壳,以防止在工业或过程控制环境中通常遇到的灰尘、污物、水和其它污染物。可以通过外壳留出端口方便连接供电和输出,与lvdt的连接通过配套卡口连接器完成。
特点:
坚固的nema-13外壳
管道端口,连接简单
4~20ma输出
螺栓孔设计,安装简单
与多种lvdt兼容
