summary

This instrument is a new intelligent instrument used to measure the surface roughness of processed parts. This instrument integrates current microprocessor technology and sensing technology, and is designed with microprocessors and integrated circuits to form an ultra small architecture that adapts to the current trend of instrument development. It can complete the collection, processing, and display of roughness parameters.

By adopting optimized circuit design and sensor structure design, the electrical box, driver, and display parts are integrated to achieve integration; Randomly select Ra and Rz measurement parameters; Not only can it measure outer circles, planes, and conical surfaces, but it can also measure grooves with a length and width greater than 80 x 30mm.

Applicable materials

Suitable for departments such as processing industry, manufacturing industry, testing, and commercial inspection, it is mainly suitable for on-site inspection of large workpieces and production lines, as well as external inspection by departments such as testing, measurement, and commercial inspection.

Basic Principles

When the sensor moves uniformly in a straight line along the measured surface under the drive of the driving mechanism, the internal contact pins perpendicular to the working surface produce vertical displacement with the micro uneven contour of the working surface. The displacement change is then converted into a change in electrical quantity through the sensor, and the electrical signal is amplified, filtered, converted into a digital signal through A/D, and then processed by DSP to calculate the values of Ra, Rz, Rq, and Rt and displayed.
