Himmelstein LVDT's (Linear Variable Differential Transformer) will provide an extremely precise measurement of displacement for most gaging applications. They combine the rugged construction required for industrial applications with the precision normally associated with laboratory devices. These models are ideally suited for electronic gaging systems, automatic inspection systems and position feedback control.
