The miniature LS-LVDT provides fast response and rugged packaging and is ideal for linear control and precision measurement applications. Configuration options provide cutting-edge features, including sub-micron resolution, linear analog output, flat dynamic response to kHz levels, and very low temperature coefficients. The free sliding transducer core is lightweight, strong, and corrosion-resistant. Cores are precision ground to ensure a close sliding fit within the open bore of the stainless steel lined LS-LVDT body. This precision allows the LS-LVDT to achieve extremely high repeatability. The sensing head is capable of total submersion in aqueous environments.
