NewTek core rod kits mate seamlessly to standard LVDTs for simple installation and linking between the LVDT core and measured object.  Made of non-magnetic 300-series stainless steel, these rods provide a rugged connection without interfering with the magnetic coupling between the core and the LVDTs internal coils.

Each core rod kit includes the core rod, Loctite packet, and two (2) jam nuts.  One end of the core rod has male threads to connect to standard cores.  Using Loctite on this joint ensures a sturdy connection. the other end of the core rod has external threads that can mate directly to the measured object, or linked to a moving plate with use of the included jam nuts.

Upon request, NewTek engineering can offer assistance and suggest the appropriate core rod kit for any application or LVDT.  In addition to the standard lengths above, custom core rod kits are also available.
