What is the working principle of a rail profilometer?
Rail profilometer with a stylus instrument and the measured surface slip measurement, direct measurement of the rail surface, such as surface roughness, hole slot, according to certain standard readings or directly depict the surface contour shape, measuring speed, reliable and convenient operation. The tested surface is easy to be scratched by the contact pin, and the measuring pressure is minimized as long as the reliable contact is ensured, and the accuracy is ensured by the high precision device, such as hydraulic pressure or air floating guide rail.
Two dimensional scanning sensor ZLDS200 series is a small range, high speed and high precision two-dimensional sensor, with digital, integrated structure. The two-dimensional laser sensor ZLDS200 series with high precision can reach Z per second, 0.1% 1200 axis scanning contour data of high response and high degree of protection IP67, and synchronization characteristics of high performance, and in addition to the standard series of products, can also be customized according to the user's special needs.
The rail profilometer is an instrument for testing and checking the profile, two-dimensional dimension and two-dimensional displacement of the rail. According to the principle of the sensor, the rail profilometer is divided into inductance, induction and piezoelectric type.
