LVDT8 Snap-mounted Displacement Sensor Overview:
Differential transformer displacement sensor (LVDT) can be widely used in crack measurement and monitoring, bridge measurement and monitoring, aerospace, machinery, construction, textile, railway, coal, metallurgy, plastics, chemical industry and scientific research colleges and other national economy all walks of life, used to measure elongation, vibration, object thickness, expansion and other high-tech products.
LVDT8 snap-mounted displacement sensor has excellent performance and is suitable for high precision, high repeatability measurements in quality control and metrological applications. The probe is made of high hardness wear-resistant silicon nitride ceramic, and the moving part of the measuring shaft is made of precision guide rail. Pen displacement sensor external transmitter can output standard DC signal, using a 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.
