The measuring element is a waveguide, and the sensitive element inside the waveguide is made of special magnetostrictive material. In the measurement process, a current pulse is generated in the electronic room of the sensor, and the current pulse is transmitted in the waveguide, thereby generating a circumferential magnetic field outside the waveguide. When the magnetic field and the magnetic field generated on the waveguide acts as a moving magnetic ring with a position change In the waveguide, the magnetostriction phenomenon is generated in the waveguide, and a strain pulse is generated. The position of the movable magnetic ring is determined according to the strain pulse.
The shell surface is anodized to prevent corrosion; the built-in imported waveguide wire is used as a measurement unit and processed by DSP digital signals with high accuracy, no temperature drift, no contact, and a life of up to 20 years; the slider ball head has an automatic centering function. Easy to install, allow extreme speed of 10m / s.
The linear digital displacement sensor drives the samarium-cobalt alloy material to move in the fixed Hall chip when the measured object moves through the retractable measuring rod, and uses the Hall effect to output a voltage signal. The signal directly enters a 16-bit single-chip microcomputer for sampling, and after being converted into a digital signal, its position is non-linearly encoded, and finally the displacement digital quantity is directly output according to the RS485 standard.
Product application: Widely used in position measurement fields such as civil engineering, geotechnical engineering, machinery, water conservancy and hydropower.
Product advantages: non-contact measurement, avoid the impact of contact measurement product life
