LVDT sensor WLU
Special design displacement transducer for safety and hydraulic valves in the power plant sector. The LVDT sensor with a Case diameter of 16 mm has a coil unit with a fully symmetrical coil design according to the LVIT differential choke principle in a half-bridge circuit. The design guarantees high temperature stability with very low temperature drift.
