Hermetically Sealed

HIR-750 Series 4-20 mA LVDT

The NewTek HIR Series sensors are rugged hermetically sealed 4-20 mA LVDTs with excellent linearity, high resolution, and superior repeatability.? These sensors are constructed of 3/4 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 0.1 inches (2.54mm) to 20 inches (500mm).  In addition to being sealed to IP-68, the HIR Series windings are potted inside the housing with a 2 component epoxy, providing excellent protection against hostile environments.
