Signal Conditioning and Displays

The IEM/421 is a power line operated current transmitter expressly designed for industrial and process control applications utilizing LVDTs and RVDTs. Its output is 4-20 mA current into a loop resistance up to 500 Ohms. It also features 100% zero suppression, which permits the entire displacement range of an LVDT-type transducer to be used. Excellent linearity 100% zero suppression Wide range demodulator phase adjustment NEMA 13 enclosure 4-20 mA current output Transducer Excitation: 3.5 V rms (nominal); internally adjustable from 2-5 V rms, 25 mA (maximum) Excitation Frequency: 2.5 kHz nominal Input Impedance: 100 Kohms
