Linear variable differential transformers (LVDTs) from RDP Electrosense are electromechanical transducers used to monitor railway tracks. Continuous welded railway tracks can be subjected to stress or compression as temperatures change or can misalign as movement takes place. Engineering companies use RDP LVDTs to conduct tests for expansion, movement, and alignment. The LVDTs are designed to be installed in carriers, resisting damage when bolted directly to the side of the rail. Stainless steel LVDTs also offer improved accuracy, high cycle life, and infinite resolution. The transformers are suitable for shock and vibration exposure applications and feature resistance to extreme temperatures, water, and corrosive fluids. RDP offers both standard and custom models to accommodate mechanical/mounting requirements and various environmental conditions.
