Principle
When measuring the surface roughness of the workpiece, the instrument first places the Sensor on the surface of the workpiece to be measured, and then starts the instrument for measurement. The sensor is driven by the precision drive mechanism inside the instrument to slide along the measured surface in a straight line with constant velocity. The Sensor feels the asperity of the measured surface through the built-in sharp stylus. At this time, the roughness of the measured surface of the workpiece will cause the stylus to be displaced, which changes the inductance of the Sensor inductance coil, thereby generating an analog signal proportional to the measured surface roughness at the output end of the phase sensitive detector. After the signal is amplified and level converted into the data collection system, the DSP chip performs digital filtering and parameter calculation on the collected data, the measurement results are given on the display, can also be output on the printer, and can also communicate with the PC.
Applications
Processing industry, manufacturing, testing, commodity inspection and other departments, mainly suitable for on-site inspection of large workpieces and production lines, as well as verification of inspection, Measurement, commodity inspection and other departments
Steps
1. Place the Sensor on the measured surface of the workpiece;
2. Start the instrument for measurement;
3. The instrument automatically drives the Sensor to slide along the measured surface and collect data;
4. The DSP chip processes data and calculates parameters.
5. The measurement results are displayed on the monitor or output to the printer.
Notice
• Make sure the Sensor stylus is in good condition before use to avoid damage;
• Keep the surface of the workpiece clean during measurement to avoid affecting the accuracy;
• Charge in time and pay attention to the remaining power indicator;
• Avoid use in extreme environments to prevent instrument failure;
• Pay attention to capacity limitations when storing data and back up in time;
When connecting external devices such as printers, ensure compatibility.
