8-Channel LVDT Input Module for SCXI—The SCXI-1540 is a linear variable differential transformer (LVDT) module that provides the necessary conditioning to measure signals from transformer-based ratiometric position sensors, including LVDTs, rotary variable differential transformers (RVDTs), and resolvers. The SCXI-1540 offers both 4- and 5-wire connections for LVDTs and RVDTs. In addition, this module provides autocalibration without external hardware using NI-DAQmx software. With random scanning capabilities, you acquire data from only the channels you select.
