The HD-190-AC Series general‑purpose AC LVDTs are designed for industrial displacement and position feedback applications. Available in stroke ranges from 20mm to 500mm (customizable). 19mm diameter stainless steel housing with separate core and coil assembly for easy installation. Typical linearity <0.3% FS, repeatability <0.1%. Operating temperature from -50℃ to +155℃ (high‑temp option to +240℃). Dual shielding provides EMI/ESD immunity; compact winding design. Ideal for steam turbines, hydraulic cylinders, oil presses, machine tools, material testing, metallurgical and mining machinery.
