spring-loaded LVDT displacement sensor
LVDT is a hightech product used to measure the elongation, vibration, thickness, expansion and so on, it is intended for widely application in Aerospace, Machinery, Construction, Textile, Railway, Coal mine, Metallurgy, Plastic, Chemical industry and Academic research.
DC LVDT performs excellently from 9-28 voltage DC power supply, suitable for high precision and high repeatability measurement, output standard signal of 0-5v or 4-20mA to be identified by computer or PLC. The integrated circuit is hermetically sealed in SUS 304 stainless steel sleeve, ensure that the transducers keep working accurately and reliably in hostile.
