NewTek - Model HAR Series -Sensor Selector
The NewTek HAR Series sensors are rugged hermetically sealed AC LVDTs with excellent linearity, high sensitivity and infinite resolution. These sensors are constructed of 0.750 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.
