Radiation resistant linear position sensors

10 October 2015

Macro Sensors radiation resistant LVDT linear position sensors provide accurate feedback of control valve position within nuclear power generation plants.

Constructed from stainless steel, the HSTAR 750 Series of Hermetically Sealed LVDT linear position sensors can be specified to withstand exposure to radiation at 3x107 Rads for 40 years.

Available in ranges of ±1.25mm to ±250mm, the LVDT sensors feature high resolution, excellent repeatability, and low hysteresis, as well as the highest sensitivity consistent with good linearity.

Electrical termination of the HSTAR 750 Series LVDTs is made through a sealed radial connector located near one end. The radial connector results in a through-bore design that permits access to either or both ends of the unit’s core for better mechanical support and core guidance, and easier clean-out in dusty or dirty locations.

The radial connector also has a shorter installed length, making the length of these sensors shorter than comparable units with an axially mounted connector for easier installation in tight spaces.
