Linear displacement transducer SXL

non-contactinductiveLVDT

Product Overview
LVDT displacement transducers from eddylab GmbH are inductive full bridges that operate wear-free and offer a theoretically unlimited mechanical service life. The differential measuring principle of these LVDTs ensures minimal temperature and EMC effects on measurement results. Despite their high resolution and repeatability, these sensors are known for their exceptional ruggedness and reliability under harsh conditions. The sensors cover measuring ranges from 10 to 400 mm.

Applications

• 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
• Position and diameter measurement of nuclear fuel rods

Key Features

• Exceptional durability with innovative, fully inorganic construction for excellent radiation resistance
• Robust design provides high resistance to vibration, shock, and seismic loads
• Reliable operation at temperatures up to 400 °C
• Hermetic sealing, including a patented connector system for maximum safety and long-term performance in demanding nuclear environments
• Differential measuring principle allows cable lengths of more than 200 m between sensor and signal conditioner without loss of precision or reliability
• Electronics are installed separately in a protected area outside the containment (e.g., K3 environment)
