Hermetically Sealed

HE-750 Series 0-10V DC LVDT

The NewTek HE Series sensors are rugged hermetically sealed 0 – 10V DC LVDTs with excellent linearity, high resolution, and superior repeatability.  These sensors are constructed of ¾ inch diameter stainless steel and manufactured for general industrial use.  Electrical connection is made through an axial mounted connector.  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 HE Series windings are potted inside the housing with a 2 component epoxy, providing excellent protection against hostile environments.
