LVDT for Valves Product Introduction

Designed for proportional/servo valve spool feedback, the HD‑270 DC Series LVDT features a 27 mm diameter with M14×1.5 threaded pressure tube for direct valve mounting — no extra bracket needed. One‑piece pressure tube with ED‑seal withstands 50 MPa with zero leakage, while 400 Hz mechanical response ensures accurate dynamic sensing. Split‑core design simplifies installation, and built‑in shielding ensures reliable operation. Available in 8 strokes from 6 mm to 50 mm, with M12 connector and multiple analog outputs (0‑5V, 0‑10V, ±5V, ±10V, 4‑20mA) for seamless system integration. Ideal for proportional valves, servo valves, directional control valves, die‑casting machines, injection molding machines, CNC machine tools, and construction machinery.
