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 institutions 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 sensors offer excellent performance and are suitable for high precision, high repeatability measurements in quality control and metrology applications. The probe is made of silicon nitride ceramic with high hardness and wear-resistant material, 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 tube, can work in wet and dust and other harsh environment. The output signal is a standard 0-5V,0-10V, 4-20mA or RS485 output that can be used by a computer or PLC.

LVDT8 snap-mounted displacement sensor selection guide:
Wiring method:
Attention!!! The sensor pen and transmitter must be used together (with the same pen number as the transmitter number), and it is prohibited to exchange them randomly, otherwise the linear accuracy of the sensor will be severely distorted

Mechanical dimensions of LVDT8 snap-mounted displacement sensor:
PS: 1. LVDT8 measuring pen without dust cover has a shorter length and added shielding function, solving the problem of mutual interference between measuring pens. More suitable for matrix installation scenarios, with a minimum installation spacing of 5-10mm for measuring pens. The vulnerable parts of the measuring pen, such as the iron core and spring, can be easily replaced.
2. LVDT8 measuring pen with dust cover is more suitable for environments with dust. If matrix installation is required, the installation distance of each measuring pen should not be less than 40mm. If a smaller installation distance is required, additional shielding function needs to be customized.
