The Easy Way to Interface an LVDT to Digital

Hybrid ICs Provide Direct Transducer-to-Digital Conversion; Tracking Converters are Amplitude-Insensitive—Have Resolutions to 16 Bits

LVDTs (linear variable differential transformers) have been used for many years in the measurement of position—and quantities that can be represented by a linear displacement, such as pressure and force. A number of features make them nearly ideal as transducers: ruggedness, frictionless operation, long mechanical life, excellent repeatability, essentially infinite resolution, and input/output isolation. Read full article
