Principle
When the sensor moves in a uniform linear motion along the measured surface under the drive of the driving mechanism, the stylus perpendicular to the working surface inside produces a vertical displacement with the microscopic uneven contour of the working surface, and then converts the displacement change into the change of electricity through the sensor, amplifies and filters the electrical signal, converts it into a digital signal through A/D, and then processes it by DSP to calculate and display the values of Ra, Rz, Rq and Rt.
Introduction
The pocket surface roughness Tester is a new intelligent instrument dedicated to measuring the surface roughness of the machined parts. The instrument integrates today's microprocessor technology and sensing technology, with advanced microprocessor and preferably highly integrated circuit design, it constitutes an ultra-small architecture that adapts to the development trend of today's instrument, and can complete the acquisition, processing and display of roughness parameters. It is suitable for processing industry, manufacturing, testing, commodity inspection and other departments, especially for the on-site inspection of large workpieces and production lines, as well as the out-of-office verification of testing, measurement, commodity inspection and other departments. It can not only measure the outer circle, plane, and conical surface, but also measure the groove with a length × width greater than 8030mm.
Functions & Features
The shape is made of ABS engineering injection molding, which is durable and durable, and has remarkable anti-electromagnetic interference ability, which is in line with today's new design trends. Compared with the previous metal shell painting process, ABS engineering plastics will not peel off the paint, and the appearance is better preserved.
The high-speed DSP processor is used for data processing and calculation, and the measurement and calculation degree are greatly improved.
The display LCD adopts the popular OLED display, high brightness, no Viewing Angle, wide temperature, suitable for various occasions.
Using lithium-ion rechargeable battery, it can work for a long time, no memory effect, can work while charging, short charging time, and long battery life.
Dot matrix LCD display, the interface prompts rich information.
Real-time monitoring of lithium battery power and display, timely reminder of the user for charging and charging progress prompt.
The automatic shutdown function and low-power hardware and software design make the instrument work for a long time, suitable for a variety of field use.
The sensor probe has a protective door, which effectively protects the sensor probe and ensures the accuracy of measurement.
Applicable Materials
It is suitable for processing industry, manufacturing, testing, commodity inspection and other departments, mainly suitable for on-site inspection of large workpieces and production lines, as well as out-of-office verification of testing, measurement, commodity inspection and other departments.
