: Common ranges span from ±0.1 mm to ±25 cm . Choosing a stroke length that closely matches your application ensures maximum sensitivity. Technical Selection Checklist AC-Operated LVDT DC-Operated LVDT Electronics Requires external signal conditioning Built-in conditioning electronics Complexity Higher; needs separate excitation/demodulation Lower; simple "plug and play" Size Generally more compact Slightly larger to house internal circuitry Stability More stable at extreme temperatures Susceptible to temperature-induced drift
: Often housed in stainless steel, LVDTs are resistant to shock, vibration, and extreme temperatures (standard ranges often cover -30°C to +85°C , with high-temp versions reaching +150°C or more). buy lvdt
If you are integrating into a modern PLC or digital system, a DC LVDT with a 4-20mA or 0-10V output is typically the easiest to implement. For extreme aerospace or vacuum environments where electronics cannot reside near the sensor, an AC LVDT is the standard choice.
