: For wet or corrosive environments, look for IP67 or hermetically sealed models to protect internal windings from moisture and contaminants.
: Since LVDTs operate on electromagnetic principles rather than mechanical steps, they can detect infinitesimally small changes in position, limited only by the quality of your signal conditioning electronics.
: Most industrial LVDTs offer linearity of ±0.25% or better over their full sensing range, ensuring a highly accurate proportional output. buy lvdt
: Ability to follow rapid movements without lag from friction.
: 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). : For wet or corrosive environments, look for
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. Linear Variable Differential Transformers - Analog Devices
: No parts to wear out during operation. : Ability to follow rapid movements without lag
: 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
