　　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

　　典型應(yīng)用: 汽輪機(jī)節(jié)流閥閥位反饋，紙漿工業(yè)，石化工業(yè)過(guò)程控制，輥筒間隙過(guò)程控制

　　行業(yè): 工業(yè)控制

　　產(chǎn)品描述:

　　IEM 422是一款電流變送器，由電源和LVDT信號(hào)處理模塊組成，115V或230VAC供電，輸出為4-20mA。IEM 422提供正弦交流電壓以驅(qū)動(dòng)LVDT，然后調(diào)制解調(diào)并放大LVDT的輸出。全波同步解調(diào)可最大限度的消除方波輸出和噪音。IEM 422采用堅(jiān)固的NEMA 13外殼，以防止在工業(yè)或過(guò)程控制環(huán)境中通常遇到的灰塵、污物、水和其它污染物。可以通過(guò)外殼留出端口方便連接供電和輸出，與LVDT的連接通過(guò)配套卡口連接器完成。

　　特點(diǎn):

　　堅(jiān)固的NEMA-13外殼
　　管道端口，連接簡(jiǎn)單
　　4~20mA輸出
　　螺栓孔設(shè)計(jì)，安裝簡(jiǎn)單
　　與多種LVDT兼容
