R-812 Series LVDT Position Sensor

The NewTek R-812 Series AC LVDTs satisfy numerous applications in which LVDT performance and reliability are required. The R-812 Series can be designed with a number of standard options including mild radiation resistance, Teflon bore, metric threaded core, and high temperature (400°F).

Description

These linear displacement sensors, from NewTek Sensor Solutions, are available in ranges of ±0.50 inch (±1.27mm) to ±10 inches. The R-812 Series sensor construction consists of a coil assembly potted and mechanically swaged into a 0.812 inch (20.6mm) diameter housing with a separate moving core. The 1/4 inch (6.35mm) diameter core allows a radial clearance of 1/16 inch (1.58mm) between the movable core and the bore of the coil assembly. The large core-to- bore radial clearance provides for ample installation misalignments.
