Working Principle

When measuring the surface roughness of the workpiece, the instrument first puts the sensor on the workpiece to be measured.On the surface, then the starting instrument is measured, and the sensor is driven by the precision driving mechanism inside the instrument.The device glides along the measured surface for a straight line, and the sensor is measured by a built-in sharp touch needle.The roughness of the surface, when the roughness of the surface of the workpiece is measured, causes the needle to produce the displacement.The displacement changes the inductance of the inductance coil of the sensor, thus the output of the phase sensitive detector.The end produces an analog signal proportional to the measured surface roughness, which is amplified and level.After the conversion, the data acquisition system is entered, and the DSP chip is digital filtering for the collected data.

Description

KS100 Standard Pickup

KS100 Standard Pickup, to measure most of the plane, inclined plane, cone surface, inner hole, groove and other   surface roughness, in addition to the standard sensor, other special sensors   are needed to measure the measuring platform.

KS110 pickup for curved surface

KS110 pickup for curved surface, to measure smooth cylindrical surface which radius is larger than 3mm, for the large radius smooth spherical surface and other surface also can obtain good approximation, need to work with platform KA520 or KA620.

KS120 pickup for small holes

KS120 pickup for small holes, to measure the inner surfaces of holes with radius more than 2mm, better to work with platform KA520 or KA620.

KS131 pickup for deep grooves

KS131 pickup for deep grooves, measure groove with width wider than 3mm and depth deeper than 10mm, or the surface roughness of step with height less than 10mm, also can used to measure the   planar, cylindrical used with platform,better to work with platform KA520 or   KA620.

 KA520 Surface Roughness Measuring Platform

KA520 Surface Roughness Measuring Platform, adjustable height 200mm.

With flexible and stable operation and wider application range. Roughness of complex shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.

Surface Roughness Measuring Platform

KA620 Surface Roughness Measuring Platform, adjustable height 300mm.

With flexible and stable operation and wider application range. Roughness of complex shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.

Surface roughness standard template

Surface roughness standard template,Made by optical glass, with high hardness, high accuracy standard roughness value, anti-scratch, has longer life than   metal roughness block.

Meet standard GB/T19067.1-2003 and   ISO5436-1:2000

Approximation: Ra=0.1um, 0.2um,   0.4um,  0.8um, 1.6um, 3.2um, 6.4um

Customized Value and Sine Wave available,   welcome to inquire.
