LVDT20 rebound displacement sensor manual
Differential transformer displacement sensor (LVDT) can be widely used in aerospace,
machinery, construction, textile, railway, coal, metallurgy, plastics, chemical and
scientific research institutions, etc., to measure elongation, vibration, High-tech
products such as object thickness and expansion.
DC LVDT has excellent performance, convenient single power supply +12~24V DC power supply,
electronic circuit sealed in 304 stainless steel metal tube, can work in harsh environment
such as humidity and dust, output signal is standard and can be used by computer or PLC
