Radiation-Resistant LVDTs

Radiation Resistant LVDTs for Nuclear Power, Defense, and Space

NewTek designs and manufactures position sensors for the most demanding environments in the presence of radiation. Able to withstand up to 100 MRad total integrated flux, NewTek LVDTs are ideal to make critical position measurements in autoclaves, particle accelerators, nuclear plants, defense applications, submarines, and space.  These LVDTs are made of special radiation-tolerant materials that will operate continuously without failure or decay.

The most common applications for radiation resistant LVDTs include measuring position of nuclear fuel and control rods in power generation, missile fins, nuclear plant steam and control valves, particle accelerator components, submarine valves and fins, and actuators and components of objects in space.

NewTek offers radiation resistant options on most standard and semi-custom AC LVDTs and on LVDTs with temperature ratings from cryogenic to 500°C.   Radiation resist LVDTs can be mounted in irradiated areas while the associated signal conditioning electronics can be mounted in a shielded location – sometimes hundreds of feet away from the sensor.

Radiation Certifications

Radiation Certificate 50 MRad
NewTek radiation resistant LVDTs have been tested and approved for exposure to 50 MRad gamma by India’s Board of Radiation and Isotope Technology, a member of the International Atomic Energy Agency (IAEA).  Tests are ongoing for higher exposure levels.

For more NewTek sensors, see our product selector.  Most AC LVDTs can be offered with radiation resistance to 30 MRad or 100 MRad.
