Principle
When the AR-132B surface roughness instrument measures the surface roughness of the workpiece, the Sensor is placed on the measured surface of the workpiece, and the driving mechanism inside the instrument drives the Sensor to slide along the measured surface at a constant speed. The Sensor senses the asperity of the measured surface through the built-in sharp stylus. At this time, the asperity of the measured surface of the workpiece causes the stylus to shift, which changes the Inductance of the Sensor Inductance coil, thereby generating an analog signal proportional to the measured surface roughness at the output of the phase sensitive rectifier. The signal after amplification and level conversion into the data collection system, the DSP chip will collect data for digital filtering and parameter calculation, measurement results displayed on the liquid crystal display, while communicating with the PC.
Applications
Production site, machined parts surface roughness measurement, inclined surface, outer cylindrical surface, inner hole surface, deep groove surface, arc surface, spherical surface
Standards
GB-T6062、ISO、DIN、ANSI、JIS
Steps
1. Place the Sensor on the measured surface of the workpiece
2. Select the sampling length
3. Measurement parameter selection
4. Press the measurement button to start measurement
5. View the measurement results displayed on the LCD display

Notice
* It needs to be used with the bracket when measuring the surface of various parts such as inclined surface, outer cylindrical surface, inner hole surface, deep groove surface, arc surface and spherical surface
* Pay attention to the protection of the Sensor stylus to avoid damage
Regularly calibrate the instrument
* Pay attention to the battery level and charge it in time.
* Sensor should be kept in good contact with the measured surface during measurement
