High Temperature

HATR-750 Series

The NewTek HATR Series sensors are rugged hermetically sealed AC LVDTs suitable for operation at 400°F (204°C) with excellent linearity, high sensitivity and infinite resolution. These sensors are constructed of 0.750 inch diameter stainless steel and manufactured for 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 HATR Series windings are potted inside the hermetically sealed housing with epoxy, providing excellent protection against hostile environments.
