Product Name:LVDT8 Micro Transmitter Type Displacement Sensor
Product Summary:

Differential transformer displacement sensor (LVDT) can be widely used in aerospace, machinery, construction, textile, railway, coal, metallurgy, plastics, chemical industry and scientific research institutions and other national economy in all walks of life, used to measure elongation, vibration, object thickness, expansion and other high-tech products.

LVDT8 pen displacement sensor has excellent performance, suitable for high precision, high repeatability measurement in quality control and metrology applications. The probe adopts wear-resistant material silicon nitride ceramic with high hardness, and the moving part of the measuring shaft adopts precision guide rail. The pen displacement sensor with transmitter can output standard DC signal, using convenient single power supply +12 ~ 30V DC power supply, electronic circuit sealed in 304 stainless steel metal tube, can work in damp and dust and other harsh environment. The output signal is standard 0-5V,0-10V, 4-20mA or RS485 output that can be used by a computer or PLC.
