ABEK Sensors has launched the TRAD19 series of strong nuclear radiation resistant LVDT position sensors, which are suitable for position measurement applications in the presence of high-flux nuclear radiation irradiation, such as nuclear fuel assembly pool side inspection, nuclear valve position feedback, superconducting proton accelerator, particle accelerator collimator, etc.
The TRAD19 series is produced with special materials and processes, which can work normally at a total irradiation dose of 1000kGy, and the series can also work continuously and stably at a high temperature of 200°C.
This series of LVDT sensors has the technical advantages of high resolution, good repeatability, low impedance, high sensitivity, good linearity, environmental adaptability and high reliability. The maximum linearity error is not more than ±0.25%.
TRAD19 series has a variety of technical indicators for customers to choose, in addition to the options already provided in the selection table, it can also be customized according to customer requirements in many aspects, including thread specifications, outlet methods, joint types and many other mechanical structure needs; As well as the adaptation of many special application environments such as high pressure resistance and high temperature resistance.
In order to facilitate the actual application of the customer, we also supply a variety of accessories to match the sensor, the series of related mounting fixtures, signal processing equipment, cables and other accessories, please contact us for information.
