Introduction
LVDT is a high-tech 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 environment of damp and dust, corrosion, etc.

Features
Outer diameterΦ20mm ,304 stainless steel shell, separate-core.
DC single power supply, built-in excellent signal demodulator.
Three wires voltage output 0-5V or 0-10V, two wires current output 4-20mA.
Measuring range from 1mm-250mm, high resolution, excellent repeatability
Contactless operation, long life.

Applications
Machine tools and instrument positioning.
Hydraulic cylinder positioning.
Cement industry, bridge deck shift detection.
The valve position detection and control.
The subway tunnel engineering protection.
