Utilizing differential sensing technology, inductive displacement Inelta IZAL series sensors ensure precise path length measurements in confined-space applications. Housing of these LVDT sensors has 4 mm dia, and interior provides complete differential transformer measuring system with core and coils. With contactless and wear-free design, displacement and position sensors achieve linearity tolerance of ± 0.5% (0.25% optional) and are designed for measuring ranges of 1, 2.5, and 5 mm.
