LVDT displacement transducers from eddylab GmbH are inductive full bridges that work wear-free and have a theoretically unlimited mechanical service life. The differential measuring principle of our LVDTs ensures minimum temperature and EMC effects on the measurement results. The LVDTs are characterized by their exceptional ruggedness and reliability under harsh conditions, despite their high resolution and repeatability. The sensors cover measuring ranges from 10 to 400 mm.
Most common nuclear applications are steam pipe monitoring of the primary and secondary circuit, structural health monitoring SHM, measuring positions of actuators, valves, hydraulic cylinders, shock absorbers of steam generators and pumps as well as position and diameter of nuclear fuel rods.
Our nuclear-grade sensors combine exceptional durability with innovative design. Their fully inorganic construction ensures excellent radiation resistance, while the robust design provides high resistance to vibration, shock, and seismic loads. Operation is highly reliably at temperatures up to 400 °C and feature hermetic sealing, including our patented connector system for maximum safety and long-term performance in the most demanding nuclear environments. The differential measuring principle of LVDT sensors allows cable lengths of more than 200 m between sensor and signal conditioner without any loss of precision or reliability. The electronics are installed separately and in a protected area outside the containment e.g., K3 environment.
