ABEK SENSORS provides highly reliable position feedback solutions for diverse nuclear radiation environments, covering both nuclear-grade and non-nuclear-grade applications. Typical scenarios include nuclear fuel element elongation measurement, collimator positioning for scattered neutron sources, safety valve position monitoring in nuclear power plants, reactor vessel deformation detection, and pool-side inspection of nuclear fuel assemblies.

In nuclear power plant, valve position monitoring is critical to operational safety. Our LVDT sensors provide operators with precise, real-time feedback on valve opening, ensuring accurate and reliable control. Additionally, these sensors can monitor thermal expansion of turbine casings during startup, shutdown, and operation. By continuously measuring casing deformation, they help determine whether thermal growth remains within expected limits, safeguarding stable unit operation.

For turbine bearing condition monitoring, our FHTA19 series sealed position sensors can be installed at critical measurement points to continuously monitor bearing vibration and clearance changes. This enables early warning of wear trends, preventing unplanned shutdowns.

The radiation dose accumulated in certain areas of the nuclear power plant can reach 1000 kGy, which far exceeds the endurance limit of normal electronic devices. ABEK SENSORS' radiation-resistant LVDT position sensor features an AC design, and the signal conditioner is mounted in an environment away from nuclear radiation. Only sensors are placed in harsh environments, ensuring long-term stability and accurate measurements even under strong radiation conditions.
