The NewTek HAR Series sensors are rugged hermetically sealed AC LVDTs with excellent linearity, high sensitivity and infinite resolution. These sensors are constructed of ¾ inch diameter stainless steel and manufactured for general industrial use. Electrical connection is made through a radially mounted connector, resulting in a reduced housing length. Designed for a wide range of position measurement applications, they are available in ranges of ±0.05 inch (1.27mm) to ±10 inches (250mm). The HAR Series windings are potted inside the housing with a 2 component epoxy, providing excellent protection against hostile environments.
