Dual RVDT-213, for most applications where angle is measured, has output linearly proportional to angular position of shaft. Its rugged construction not only provides high performance and reliability, but also enhanced resistance to shocks / vibrations typical of industrial / defense environments. Mechanically able to rotate continually, Dual RVDT-213 offers linear measurement up to 13 deg, with linearity better than ±0.5% of Full Scale. Magnetically shielded, it offers essentially infinite resolution, limited only by signal condition. Requires AC voltage excitation to primary coil, produces AC voltage from secondary coil, proportional to shaft position. All materials and test methods are according to MIL-STD.
